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
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.
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 ...
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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Another example is propane-1,2-diol, or alpha propylene glycol, HO−CH 2 −CH(OH)−CH 3, used in the food and medicine industry, as well as a relatively non-poisonous antifreeze product. On commercial scales, the main route to vicinal diols is the hydrolysis of epoxides .
