Production method
It is obtained by the reaction of diethanolamine and thionyl chloride. Dissolve thionyl chloride in chloroform, and drop a mixture of diethanolamine and chloroform below 0°C. Control the droplet acceleration to maintain the temperature at -4-6 ℃. After adding, keep the temperature and stir for 30min. Stir at room temperature for 1h, heat to 60-65 ℃, after all crystallization is precipitated, add anhydrous ethanol, heat and reflux to dissolve all. Pour out while hot, cool naturally, and precipitate crystals. Filter the next day and wash twice with chloroform or absolute ethanol. Dry to obtain a finished product with a 76% yield.
