Yield:126-73-8 98%

Reaction Conditions:

with trichlorophosphate in butan-1-ol at 10 - 30; for 1.83333 h;

Steps:

4 Example 4

This example is a comparative example (Conventional Method 2) that directly utilizes sodium alkoxide as an acid scavenger. In a 2L three-necked flask containing 153.6g sodium butoxide solution 960.Og, stirring cooling to 10 ° C below, stirring drop 245.33g, 1.6mol phosphorus oxychloride, control the mixture temperature is not higher than 10 ° C. 50 minutes or so drop is completed. Heating to 30 degrees, anti-lh, the reaction is completed, add water after cooling, dissolved sodium chloride generated, liquid, collecting organic phase, organic phase washed to neutral, vacuum distillation to remove water and low boiling point butanol, Less than 96% of the crude product of tributyl phosphate 435.00g, coupled with the distillation column, vacuum distillation to get 417.6g tributyl phosphate, the yield of 98.0%, purity 99.5%
