Uses

Mainly used in the manufacture of resins, plasticizers and surfactants Neopentyl glycol has a wide range of uses, mainly used for the production of unsaturated polyester resins, oil-free alkyd resins, plasticizers for polyurethane foams and elastomers, additives for advanced lubricating oils and other fine chemicals. Neopentyl glycol is an excellent solvent and can be used for selective separation of aromatic hydrocarbons and cycloalkyl hydrocarbons. Neopentyl glycol has water resistance, chemical resistance and weather resistance. Its amino baking paint has good gloss retention and does not turn yellow. It can also be used as a raw material for the production of polymerization inhibitors, stabilizers, and pesticides. Plasticizer. Organic synthesis. Polyester synthetic raw materials.

production method

1. sodium formate isobutyraldehyde and formaldehyde are condensed in the presence of 30-35 ℃, pH 9-11, and alkali catalyst to generate hydroxyl tert-butyraldehyde, and excess formaldehyde is reduced to neopentyl glycol under strong alkali conditions, formaldehyde is oxidized and reacts with alkali to generate sodium formate. The reaction liquid is neutralized with formic acid, distilled and dehydrated under reduced pressure, and the concentrated liquid is extracted in layers. After removing sodium formate, it is cooled, crystallized and separated to obtain the finished product. 2. Hydrogenation method is obtained by condensation of isobutyraldehyde and formaldehyde to obtain hydroxyneopental, which is then obtained by hydrogenation reduction.
