| titleOfInvention | Preparation of n-(hydroxyphenyl)maleimides |
| abstract | PURPOSE: To prepare the title compound useful as a raw material of high performance rsins, and adhesives, in high yield and purity and in a short time, by hydrolyzing an ester of the title compound with an oxy-acid of sulfur or phosphorus, under specific temperature conditions. n CONSTITUTION: N-(hydroxyphenyl)maleimides of formula II are prepared by (1) dissolving N-(hydroxyphenyl)maleimide ester of formula I(R is 1-7C alkyl, phenyl; R' is H, CH 3 , C 2 H 5 , F, C1, Br, I; n is an integer of 1-5) in an oxyacid of sulfur or phosphorus (sulfuric acid, thiosulfuric acid, sulfurous acid, orthophosphoric acid, orthophosphorous acid, and/or pyrophosphoric acid), and (2) pouring the solution into water therby hydrolyzing the esters. n USE: Raw material of thermosetting resin, photo-snsitive resin, impregnating varnish, paint, and copper-clad laminate, etc. n COPYRIGHT: (C)1979,JPO&Japio |
