Embodiment 1
[0012] Add 115.6g (1.7mol) of sodium formate and 115.0g (1.55mol) of butanol to a 500mL four-necked flask equipped with a mechanical stirrer, a thermometer, a condenser and a dropping funnel, stir to dissolve them, and keep warm in an ice-water bath to 10 ℃, dropwise add 76.5g (0.5mol) phosphorus oxychloride from the dropping funnel, control the feeding rate to keep the temperature stable at about 10℃, after the dropwise addition, continue to insulate and stir for 20 minutes. Then it was changed into a distillation device, and first atmospheric distillation was carried out, and the fraction at about 101°C was collected as formic acid; then decompressed to -0.98Mpa (gauge pressure), and the fraction at about 170°C was collected as tributyl phosphate, and 125.0g was obtained. The yield was 94.0%, and the gas chromatography purity was 97.1%.
Embodiment 2
[0014] By the method of embodiment 1, the charging capacity of sodium formate is 105.4g (1.55mol), other steps are unchanged, obtains tributyl phosphate 122.8g, yield 92.3%, gas chromatography purity is 97.9%.
Embodiment 3
[0016] By the method of embodiment 1, the charging amount of butanol is 118.6g (1.6mol), other steps are unchanged, obtains tributyl phosphate 124.1g, yield 93.3%, gas chromatography purity is 98.2%.
