Steps:

7 Preparation of Low Residual Granular Potassium Butoxide

This embodiment presents a method for preparing a low residual particulate-butoxide, the method comprising the steps of: 1000ml band to microwave heating, a reflux condenser, a thermometer, a stirrer, a four-necked flask 600ml butanol (6.56mol), 200ml of anhydrous xylene under nitrogen was added 78.0 g of potassium m etal (a 2 mol), microwave heating, a frequency of 2450 ± 50MHz, the reaction temperature is controlled at 100 ° C, hydrogen gas generated by the reaction leads to no gas generating far, change distillation reflux, the excess alcohol distilled off slowly, and then xylene was distilled off, and then evaporated in vacuo the residue in xylene (degree of vacuum lOOmmHg), granular solid obtained butoxide, alcohol, and solvent residue lower than 0.01%, greater than 20 mesh size greater than 96 percent.
