Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water. By esterification reaction with fatty or carboxylic acids, synthetic lubricating esters with reduced potential for oxidation or hydrolysis, compared to natural esters, can be produced.
Resistance to Weathering
Coatings that contain neopentyl glycol have excellent resistance to weathering, which helps to protect the surface from degradation caused by exposure to sunlight, rain, and wind. This makes neopentyl glycol ideal for use in outdoor coatings, such as those used on cars, buildings, and boats.
Chemical Resistance
Neopentyl glycol is also highly resistant to chemicals, which makes it an ideal additive for coatings used in harsh chemical environments. Coatings that contain neopentyl glycol can withstand exposure to a wide range of chemicals, including acids, alkalis, and solvents.
UV Stability
Neopentyl glycol provides excellent UV stability to coatings, preventing them from yellowing or fading over time. This makes neopentyl glycol ideal for use in coatings used on outdoor surfaces that are exposed to sunlight.
Scratch Resistance
Coatings that contain neopentyl glycol have excellent scratch resistance, which helps to protect the surface from damage caused by everyday wear and tear. This makes neopentyl glycol ideal for use in coatings used on high-traffic surfaces, such as floors, countertops, and tabletops.
Improved Adhesion
Neopentyl glycol can also improve the adhesion of coatings to the surface, which helps to prevent peeling or flaking. This makes neopentyl glycol ideal for use in coatings used on surfaces that are difficult to adhere to, such as metal or plastic.
Production of neopentyl glycol, by a process wherein isobutyraldehyde and formaldehyde are condensed in the presence of an alkali catalyst to produce hydroxypivaldehyde which is subsequently hydrogenated to produce neopentyl glycol, is improved by the following steps which serve to reduce the sodium content in the hydrogenation reactor and thus prevent premature loss of activity of the hydrogenation catalyst. The effluent from the aldol condensation reactor is filtered to remove solid particles.
This filtered stream is decanted to separate it into an organic and an aqueous stream. The organic stream is diluted with water and then passed through a filter type coalescer to further reduce the sodium content. The organic stream issuing from the coalescer will typically contain less than about 15 parts per million sodium and is suitable for further processing and hydrogenation to form neopentyl glycol. As a final step to control the sodium load in the hydrogenation reactor a portion of the hydrogenation catalyst is periodically removed. This catalyst may be washed to remove sodium and subsequently reintroduced into the hydrogenation reactor.
Neopentyl Glycol as Active Supporting Media in Shape-Stabilized PCMs
The present work explores the feasibility of using polyalcohols with solid-solid phase transition as active supporting matrix of n-alkanes in shape-stabilized phase change materials (SSPCMs). It is well-established that the use of SSPCM avoids leakage and increases stability and easy handling of solid-liquid PCMs. Nevertheless, the resulting composite exhibits a loss of heat storage capacity due to the volume occupied by the supporting material, which does not contribute to latent heat storage.
Therefore, the objective of this work is to combine solid-liquid PCMs (alkanes) with solid-solid PCMs (polyalcohols), both exhibiting a phase transition in the same range of temperature, to obtain high energy density SSPCMs. Towards that goal, the performance of Neopentyl Glycol (NPG) and Docosane as a new energetic SSPCM has been proved. The NPG-Docosane chemical compatibility and its outstanding wettability facilitate the propitious association of both materials.
The higher capillary forces obtained by decreasing the NPG crystal size together with the addition of expanded graphite (EG) allowed to obtain a maximum Docosane content of 60 wt%. The addition of EG improves the shape stability at the time that increases the heat transfer properties of the composites. The analysis showed that the components of the obtained SSPCMs are able to combine their latent heats, achieving a maximum value of 210.74 J/g for the highest Docosane content. This value is much higher than those latent heats exhibited by existing SSPCMs in the same working temperature range.

Monopentaerythritol is another form of pentaerythritol, and its characteristics and application fields are different from those of tripentaerythritol and dipentaerythritol.
Dipentaerythritol is the mainstream product in the pentaerythritol market, referring to pentaerythritol with a mass fraction greater than 85%. It is an important fine chemical intermediate with advantages such as safety and non-toxicity, and is widely used in advanced lubricants, high-end coatings, synthetic resins and other fields.
Tripentaerythritol is a type of pentaerythritol, and its composition ratio and mass fraction are different from other types of pentaerythritol.
A process for the preparation of pentaerythritol, comprising reacting formaldehyde, acetaldehyde and sodium hydroxide and acidification with formic acid. These steps take place in a reactor with supplies of formaldehyde, sodium hydroxide, acetaldehyde and formic acid and at the end the solution formed is evacuated to a buffer tank of larger capacity than the reactor. In the reactor new reactions and acidifications are successively reinitiated by new supplies.
In the first place a formaldehyde solution is added, followed by simultaneous but separate additions of sodium hydroxide solution and acetaldehyde, forming a reaction mixture in such a way that the flowrates of the solutions vary with the time and that the temperature at which the reactions are conducted also varies with the time. The outflow from the buffer tank is constant and continuous.
What are the Main Applications of Pentaerythritol
Alkyd Resins
Alkyds are used in paints and in moulds for casting. They are the dominant resin or "binder" in most commercial "oil-based" coatings. Approximately 200,000 tons of alkyd resins are produced each year.
Rosin and Tall Oil Esters
Rosin is an ingredient in printing inks, photocopying and laser printing paper, varnishes, adhesives (glues), soap, paper sizing, soda, soldering fluxes, and sealing wax. The tall oil rosin finds use as a component of adhesives, rubbers, and inks, and as an emulsifier.
Special Varnishes
Varnish is a transparent, hard, protective finish or film primarily used in wood finishing but also for other materials. Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent.
Plasticizers
Plasticizers or dispersants are additives that increase the plasticity or fluidity of the material to which they are added; these include plastics, cement, concrete, wallboard, and clay.
Insecticides
An insecticide is a pesticide used against insects. They include ovicides and larvicides used against the eggs and larvae of insects respectively. Insecticides are used in agriculture, medicine, industry and the household. The use of insecticides is believed to be one of the major factors behind the increase in agricultural productivity in the 20th century
Synthetic Lubricants
Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials. Synthetic lubricant is used as a substitute for lubricant refined from petroleum when operating in extremes of temperature, because it generally provides superior mechanical and chemical properties than those found in traditional mineral oils. Aircraft turbines, for example, require the use of synthetic oils, whereas aircraft piston engines don't.
Explosives
Explosive is a substance that contains a great amount of stored energy that can produce an explosion, a sudden expansion of the material after initiation, usually accompanied by the production of light, heat, sound, and pressure.
Antioxidants
An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions.
Ink
Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescers, and other materials. Ink is a liquid that contains pigments and/or dyes and is used to colour a surface to produce an image, text, or design.
PVC Stabilizers
Polyvinyl chloride is the third most widely produced plastic, after polyethylene and polypropylene. PVC is widely used in construction because it is cheap, durable, and easy to assemble.
Paint Swelling Agents
Penta and its esters are used as ingredients in paint stripping formulations that also contains solvents, wetting agents, and swelling agents. The swelling agents help to separate the paint from substrate. The polyol portion of the Penta ester can also act as a redistribution compound via transesterification.
Radiation Curing Monomers
End-capping of isocyanate terminated polyurethane prepolymer with a monofunctional acrylate like pentaerythritol triacrylate renders the polyurethane radiation curable. Other UV-curable penta-based acrylates are pentaerythritol tetraacrylate and ethoxylated pentaerythritol tetraacrylate. Urethane acrylates have very good flexibility and very good adhesion. Acrylatyed dipentaerythritol exhibits increased crosslinking and high reactivity and offers very good hardness, scratch resistance and chemical resistance.
Pentaerythritol should be stored in a ventilated, dry, cool place, away from fire and high temperature environment.
The packaging barrel of pentaerythritol should be sealed to prevent it from being contaminated by external air, moisture and impurities.
Before using pentaerythritol, wear appropriate protective equipment, such as gloves, goggles and masks.
When using pentaerythritol, keep away from fire and high temperature environment to prevent explosion accidents.
During operation, avoid pentaerythritol from contacting vulnerable parts such as skin, eyes and mouth. Stop operation immediately if abnormal symptoms are found.
