| titleOfInvention | Method for production 2-phenylbenzoxazole |
| abstract | Usage: as a phyto-protective drug. SUMMARY OF THE INVENTION: The product is 2-phenylbenzoxazole. BF SiNeMO, yield 77.9%, etc. 101.5-102 ° C. Reagent 1: o-aminophenol. Reagent 2: benzoic acid. Reaction conditions: in the presence of boric acid in xylene medium with the addition of montmorillonite type colloidal clays with a mass ratio of o-aminophenol-clay 1: 0.1-0.5. The resulting mass is filtered, xylene is distilled off, the crude product is crystallized in isopropyl alcohol. And treated with activated carbon in isopropyl alcohol at boiling. 1 tab. 1 ill. (In order to utilize production waste. The goal is achieved in that the condensation of o-amino phenol with benzoic acid in the presence of boric acid in xylene is carried out with the addition of montmorillonite-type colloidal clays with a mass ratio of o-aminophenol-clay 1: 0,1-10, 5, the resulting mass is filtered, xylene is distilled off, the crude product is isolated by crystallization in isopropyl alcohol and it is treated activated00 § CO 00 with |
