Inquiry History

Description

Name	Neopentyl glycol
CAS number	126-30-7
Description	Neopentyl glycol contains two symmetrical primary hydroxyl groups. It can readily participate in various chemical reactions such as esterification, condensation and oxidation. Due to the presence of gem-dimethyl structure and the absence of hydrogen atoms at the β-position, it has high chemical stability and thermal stability.
Molecular Formula	C₅H₁₂O₂
Molecular Weight	104.15
Appearance	Solid powder
Quality Standard	Enterprise standard
Shipping Condition	Shipped under ambient temperature as non-hazardous chemical. This product is stable enough for a few weeks during ordinary shipping and time spent in Customs.
Storage Condition	Dry, dark and at 0~4 ℃ for short term (days to weeks) or -20 ℃ for long term (months to years).
Shelf Life	>2 years if stored properly
Sample package	Aluminium foil bag
Commercial package	Aluminium Tin, Fiber drum
Origin	China

Neopentyl glycol More Info

Synthesis Methods

Formate Method: Isobutyraldehyde and formaldehyde undergo condensation in the presence of an alkali catalyst at 30 - 35°C and pH 9 - 11 to form hydroxypivalaldehyde. Then, it is reduced to neopentyl glycol in the presence of excess formaldehyde and strong alkali, while formaldehyde is oxidized and reacts with the alkali to form sodium formate.

Hydrogenation Method: It is synthesized by condensation of isobutyraldehyde and formaldehyde to form hydroxypivalaldehyde, followed by hydrogenation and reduction.

Applications

Resin Industry: Mainly used in the production of unsaturated polyesters and saturated polyesters for the preparation of powder coatings, polyurethane resins, glass fiber reinforced unsaturated resins, etc.

Coating Industry: Utilized in the production of oil-free alkyd resins, which are widely used in coatings, insulating materials, printing inks and other industries. Coatings made from NPG have excellent fluidity, flexibility, chemical stability, hydrolysis resistance, weather resistance, etc.

Polyurethane Field: Used to produce polyester polyols, which are mainly used in non-foam polyurethanes. Polyurethanes based on neopentyl glycol have excellent hydrolysis stability, low glass transition temperature, low melting point, and good heat and UV stability.

Plasticizer: It is used to synthesize plasticizers, which give PVC excellent low-temperature resistance, low volatility and migration resistance.

Lubricant: Neopentyl glycol diester resins are used in the production of high-grade synthetic lubricants, which have excellent thermal stability in addition to low pour point, high viscosity index and high flash point.

Solvent: It is an excellent solvent and can be used for the selective separation of aromatic and cycloalkyl hydrocarbons.

Toxicity

It is of low toxicity. The oral LD₅₀ for rats is ≥6400 mg/kg, and for mice it is 3200 - 6400 mg/kg.
