Sodium Tert-Butoxide Production process

Oct 22,2024

Sodium tert-butoxide, white crystal,  at normal temperatures and pressures property stablize, have micro- evil to water, be used as organic synthesis intermediate, Medicine intermediate;Or it is widely used in condensation, rearrangement and open loop in chemical industry, medicine, pesticide and organic synthesis as highly basic Deng in reaction.

Traditional sodium tert-butoxide synthetic method is the gold that then will be cut into pieces in advance with the tert-butyl alcohol directly as solvent Belong to sodium piece to put into the tert-butyl alcohol at leisure.

Production process

99% Sodamide for measuring is added in reactor, while being slowly added dropwise a certain amount of 99% anhydrous tertiary butanol, drop finishes, stirring, 85 DEG C of insulation back flow reaction 10h of control temperature of reaction kettle.After reaction terminates, distilled, the tert-butyl alcohol is steamed(It is back in reactor), distill to not going out to evaporate, room temperature is cooled to, discharge, pack to obtain 98% sodium tert-butoxide finished product.

Whole reaction yield 76.3%.This project is condensed using three-level, including two grades of chilled brine condensations and one-level water-cooled, the tert-butyl alcohol(82.8 DEG C of boiling point), using three-level condense, condenser area is 20m2, tert-butyl alcohol condensation efficiency is 98%.
