| titleOfInvention | Method for preparation of phosphoric ester |
| abstract | A phosphoric ester is made through the following steps. Step 1: reacting a naphthol with a phosphorous oxychloride at a mole ratio of 1:1.3 under the presence of halogenized metal, and removing the unreacted phosphorous oxychloride, and then: Step 2: reacting the reactant produced by step 1 with a phenol at a mole ratio of 1:1-1.5 (mole ratio of phenol to the chlorine atom of the reactant product), and removing the by-produced hydrogen chloride, the phosphoric ester thus produced being represented by the following formula (1), wherein n is 1 or 2. |
