METHOD FOR PRODUCING AROMATIC DIPHOSPHATES |
摘要 |
A method for producing an aromatic diphosphate comprising: Step 1 which is a step where a specific aromatic monohydroxy compound having a steric hindrance group at ortho-positions is made to react with phosphorus oxyhalide in the presence of a Lewis acid catalyst and then the unreacted phosphorus oxyhalide is removed under a reduced pressure to give a specific; and Step 2 which is a step where the reaction product obtained in the above step is made to react with a specific aromatic dihydroxy compound in an amount of 0.5 mol to 1 mol of halogen contained in the reaction product in the presence of a Lewis acid catalyst to give a specific aromatic diphosphate. |
