Neopentyl Glycol
CAS No.:126-30-7
Min. Order: 1MT
Packaging: 25KG/BAG

Overview:
Neopentyl Glycol (NPG) is a white crystalline solid, odorless and hygroscopic. Neopentyl Glycol is mainly used as a plasticizer in the production of unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers, and as an additive to lubricating oils, etc. Neopentyl Glycol is also an excellent solvent for selective separation of aromatic hydrocarbons and cycloalkyl hydrocarbons, and it can be used as a raw material for the production of stabilizers and insecticides.

Functions and Applications
Neopentyl Glycol (NPG), white crystalline solid, odorless, hygroscopic. Low toxicity. Low irritation to skin. However, large amount of drinking will stimulate the central nervous system, causing vomiting, fatigue, lethargy, dyspnea, tremor, renal congestion and hemorrhage, hepatic steatosis, shutting up of urine, bronchitis and pneumonia, and even lead to death in serious cases.
Synthesis method of neopentyl glycol 1. Sodium formate method Isobutyraldehyde and formaldehyde are condensed to produce hydroxy tert-butyraldehyde in the presence of 30-35 ℃, pH 9-11, alkali catalyst, and reduced to neopentyl glycol with excess formaldehyde under the condition of strong alkali, and formaldehyde is oxidized, and sodium formate is produced by alkali action. The reaction solution is neutralized with formic acid, distilled and dehydrated under reduced pressure, and the concentrated solution is extracted by layered extraction to remove sodium formate, then cooled, crystallized and separated to obtain the finished product.2. Hydrogenation method It is obtained from isobutyraldehyde and formaldehyde by condensation to obtain hydroxyneopentylaldehyde, and then reduced by hydrogenation.
Neopentyl Glycol has a wide range of uses, mainly as a plasticizer in the production of unsaturated polyester resins, oil-free alkyd resins, polyurethane foams and elastomers, as an additive in high-grade lubricants and in other fine chemicals. Neopentyl Glycol is an excellent solvent for the selective separation of aromatic and cycloalkyl hydrocarbons. Neopentyl Glycol is resistant to water, chemicals and weathering. Its amino baking paints have good light retention and do not yellow. It is also used as a raw material for the production of polymerization inhibitors, stabilizers and pesticides.
