| titleOfInvention | Preparation of carbonate type flame-retardant |
| abstract | PURPOSE: To obtain the title flame-retardant with a low MW and suitable for flame-retarding of a thermoplastic resin with a low molding temp. by reacting a halogenated dihydric phenol and a non-halogenated dihydric phenol with phosgene under a specified condition. n CONSTITUTION: When the title flame-retardant is prepd. by reacting a mixture of 1mol of a halogenated dihydric phenol (e.g. tetrabromobisphenol A) with 0.1-0.5mol of a non-halogenated dihydric phenol with phosgene in the presence of a solvent (e.g. methylene chloride), the amt. of phosgene used is 2.2 to 3.0-fold mol based on the total amt. of the dihydric phenol, and phosgene is reacted at a pH of 11-12 and a temp. of 20-27°C in the reaction system. Then, 0.5 to 1.5-fold mol of a monohydric phenol (e.g. t-butylphenol) base on the total amt. of the dihydric phenol and a catalyst (e.g. triethylamine) are added thereto and the reaction is completed at a pH of 12.5 or higher and a temp. of 30-36°C. n COPYRIGHT: (C)1990,JPO&Japio |
