| titleOfInvention | Method for production of triarylphosphates |
| abstract | FIELD: production of triarylphosphates. SUBSTANCE: product: mixture P(O)(OR) 3 , where R is aryl. Reagent 1: POCl 3 . Reagent 2: phenol-xylenol mixture at ratio of (30-40):(70-60) in terms of mass.%, with use of phenol-xylenol mixture in form of 3.5-xylenol of the synthetic and coal kinds in ratio of 2: 1. Reaction conditions: at 170 C with return of nonreacted phenol mixture to zone of reaction in the amount of 6-10 mas.% instead of fresh phenol-xylenol mixture. EFFECT: higher efficiency. 2 cl, 1 tbl |
