A condensation reaction of neopentyl glycol with 2,6-di-tert-butylphenol gives CGP-7930. Neopentyl glycol is a precursor to Neopentyl glycol diglycidyl ether. The sequence begins with alkylation with epichlorohydrin using a Lewis acid catalyst. Dehydrochlorination of the resulting halohydrin with sodium hydroxide affords the desired ether. [5]
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 diglycidyl ether (NPGDGE) is an organic chemical in the glycidyl ether family. It is aliphatic and a colorless liquid. It has the formula C 11 H 20 O 4 and the CAS registry number of 17557-23-2. [2] It has two oxirane groups per molecule. [3] Its principle use is in modifying epoxy resins. [4] It is REACH registered.

Diglycidyl ethers are chemical compounds used as a reactive diluents for epoxy resin.Other uses include treating textiles and stabilizing chlorinated organic compounds. ...
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 ...
Nonbiological degradation is negligible. [6] Nonylphenol is partially removed during municipal wastewater treatment due to sorption to suspended solids and biotransformation. [ 19 ] [ 20 ] Many products that contain nonylphenol have "down-the-drain" applications, such as laundry and dish soap, so the contaminants are frequently introduced into ...
This is followed by a caustic dehydrochlorination, to form C12-C14 alcohol glycidyl ether. [6] The waste products are water and sodium chloride and excess caustic soda. [ 7 ] One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight.
