| 摘要 |
Hydrocarbyl bisphosphate compounds containing hindered aryl substituents in the phosphate groups can be formed by: (a) reacting a hindered phenol, e.g., xylenol, with a phosphorus oxytrihalide, e.g., phosphorus oxytrichloride, to form a reaction product mixture; and (b) combining the reaction product, without distillation of the product from the reaction product mixture, from (a) mixture with a hydrocarbyl diol, e.g., one containing a phenyl ring such as hydroquinone or resorcinol.
