Process for the preparation of isocyanates and their use for the preparation of polyisocyanates containing ester

This invention relates to a novel process for the preparation of isocyanates containing silylated alcoholic or phenolic hydroxyl groups as substituents and to the use of the compounds obtained by this process as reactants for isocyanatocarboxylic acid halides in the preparation of polyisocyanates containing ester groups.

Synthesis of Hydroxy-Substituted 4-Phenyl-1,2,4-triazoline-3,5-diones

Starting from 4-aminophenol, 4-(4-hydroxyphenyl)-1,2,4-triazoline-3,5-dione (4) and 4-(4-hydroxy-3-nitrophenyl)-1,2,4-triazoline-3,5-dione (11) are synthesized.Contrary to the base-catalyzed formation of the unsubstiuted phenyl derivative 1, the heterocycle 9 is formed by heating of 1-(ethoxycarbonyl)-4-semicarbazide (8).By treatment of 4-(4-hydroxyphenyl)urazole (9) with NO2 nitration of the aromatic ring and oxidation occur simultaneously with formation of 11.Oxidation by tert-butyl hypochlorite gives 4.First investigations on polybutadienes modified with 1, 4, 11 show the influence of the additional hydroxy group to the mechanical properties.
