Process for preparing ester compounds |
| abstract |
A process for preparing an ester compound comprising reacting a halogen-substituted aliphatic hydroxy compound or aromatic hydroxy compound with a phosphorus oxyhalide or phosphorus pentahalide in the presence of 0.005 to 10 mol % of a phosphorus trihalide with respect to the hydroxy compound to obtain a phosphoric ester compound.Phosphoric ester compounds of high purity containing less coloring components can be prepared without using an antioxidant. |
