Process for producing phosphorohalidate |
摘要 |
The present invention provides a process for producing phosphorohalidate characterized in that a crude reaction product obtained by reacting a phosphorus oxyhalide with an aromatic hydroxy compound in the presence of a Lewis acid catalyst is purified by distillation in the presence of an alkali metal salt. The process of the invention produces a high-purity phosphorohalidate in high yield which contains no impurities such as the phosphorus oxihalidate and aromatic hydroxy compound used as starting materials and the catalyst.
