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.
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 ...
TME is an intermediate in the production of alkyd and polyester resins, powder coating resins, synthetic lubricants based on polyol esters, stabilizers for plastics, plasticizers, and pigment coatings based on titanium dioxide. Trimethylolethane based resins have superior weatherability and resistance to alkali and heat.
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.
Hydroxypivalic acid neopentyl glycol ester is produced by a Tishchenko reaction from hydroxypivaldehyde in the presence of a basic catalyst (e.g., aluminium oxide). [ 7 ] The Tishchenko reaction of paraformaldehyde in the presence of aluminum methylate or magnesium methylate forms methyl formate .
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 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 ...
