| titleOfInvention | PROCESS FOR THE PRODUCTION OF GLYCIDYLAETHERS FROM POLYPHENOLS |
| abstract | Polyphenols are reacted with epichlorhydrin in the presence of phosphonium salts of formula: (in which R1 to R4 are 1-12C alkyl, cycloalkyl, aralkyl or aryl, opt. substd. e. g. with halogen, NO2, OH, CN, epoxide etc. and X is an anion). The chlorohydrin ether is treated with alkali, or org. base to remove HCI and give the glycidyl ether. The polyphenol glycidyl ethers, wit hardeners e. g. amines, polycarboxylic acids or their anhydrides, can be used as low viscosity casting resins, paints, adhesives, moulding matls. moulds etc. The glycidyl ethers are obtd. in higher quality, increased yield and shorter time than with known catalysts, e. g. alkalis, quat. ammonium salts or sulphonium salts. No decompsn. of epichlorhydrin or formation of chlorine-contg. polymers occurs. |
