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.
Dibromo neopentyl glycol diglycidyl ether is a brominated version of neopentyl glycol diglycidyl ether. It is an aliphatic organic chemical in the glycidyl ether family that is used in epoxy resin formulations. It has the molecular formula C 11 H 18 Br 2 O 4
TMP is produced via a two step process, starting with the condensation of butyraldehyde with formaldehyde: CH 3 CH 2 CH 2 CHO + 2 CH 2 O → CH 3 CH 2 C(CH 2 OH) 2 CHO. The second step entails a Cannizaro reaction: CH 3 CH 2 C(CH 2 OH) 2 CHO + CH 2 O + NaOH → CH 3 CH 2 C(CH 2 OH) 3 + NaO 2 CH. Approximately 200,000,000 kg are produced ...
Paraformaldehyde reacts with boric acid to form methyl formate. [9] The key step in the reaction mechanism for this reaction is a 1,3-hydride shift in the hemiacetal intermediate formed from two successive nucleophilic addition reactions, the first one from the catalyst. The hydride shift regenerates the alkoxide catalyst.
Trimethylolethane (TME) is the organic compound with the formula CH 3 C(CH 2 OH) 3.This colorless solid is a triol, as it contains three hydroxy functional groups.More specifically, it features three primary alcohol groups in a compact neopentyl structure.
Neopentyl alcohol can be prepared from the hydroperoxide of diisobutylene. [3] It can also be prepared by the reduction of trimethylacetic acid with lithium aluminium hydride . Neopentyl alcohol was the first described in 1891 by L. Tissier, who prepared it by reduction of a mixture of trimethyl acetic acid and trimethylacetyl chloride with ...
Neopentyl glycol and epichlorohydrin are reacted in the presence of a Lewis acid catalyst to form a halohydrin. This is followed by washing with sodium hydroxide in dehydrochlorination step. This forms Neopentyl glycol diglycidyl ether. [7] The waste products are water and sodium chloride and excess caustic soda.
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
