Steps:

6 Example 6

In a nitrogen-protected 3L round bottom three-necked flask, 110 g of dimethyl phosphite, 260 g of tert-butanol, and 3.3 g of Ca (OH)_{2 were added}; the temperature was raised to reflux with stirring, and a fraction (methanol) of 60 to 65 ° C. was collected, and then a kettle was set. The bottom temperature is 130 ° C, and the temperature is further increased to reflux under normal pressure, and the two-stage fraction (excessive t-butanol) is distilled off. The crude di-tert-butyl phosphite is obtained at the bottom of the kettle; Further distillation under reduced pressure at a pressure of 1 kPa yielded 181.3 g of di-tert-butyl phosphite with a purity of 98% and a yield of 91.5%.
