- Example 1 tetrabutyl was used instead of using benzyl bromide. The same operation as in Example 1 was performed, except that 0.04 mol of tilammonium bromide was used. Table 3 shows the yield and HPLC purity of the obtained pentaerythritol dibenzylphosphonate.
- Example 2 The same operation as in Example 1 was carried out except that, in (C) of Example 1, phenyl bromide was used in an amount of 0.12 mol instead of using benzyl bromide.
- Table 3 shows the yield and HPLC purity of the obtained Penri-erythri 1 ⁇ -l-dibenzylphosphonate.
- Example 1 In (C) of Example 1, the same operation as in Example 1 was performed except that the reaction temperature was adjusted to 40 ° C. No erythritol dibenzylphosphonate was obtained.
- Example 1 In (C) of Example 1, the same operation as in Example 1 was performed except that benzyl bromide was not used. Almost no erythritol dibenzylphosphonate was obtained.
- specific phenol erythritol diphosphonate that can be used as a flame retardant or the like can be provided in a highly pure, high yield, and industrially advantageous method with excellent productivity.
