Verfahren zur kontinuierlichen Herstellung von Alkalialkoholaten

摘要

Continuous preparation of alkali metal alcoholates by reacting at elevated temperature an aliphatic or cycloaliphatic monohydric alcohol (2-12 C) with an alkali metal alcoholate derived from a monohydric alcohol (1 or 2C) which has a lower boiling-point than the higher alcohol to produce the desired alkali metal alcoholate together with the liberated lower alcohol and then introducing gaseous higher alcohol into the reaction mixture thus obtained to drive off from the mixture a gas comprising the lower alcohol. The specified higher alcohols have primary, secondary or tertiary hydroxy groups. The process may be carried out at a pressure other than atmospheric, preferably at the boiling point of the reaction mixture. Examples describe the preparation of sodium n-propylate, sodium isopropylate, and potassium tert-butylate.
