Magnesium tert-butoxide Usage And Synthesis

Chemical Properties

White to light grey powder

Uses

Magnesium tert-butoxide is used as a pharmaceutical intermediate. It is also used in deprotonation reactions for organic syntheses.

Synthesis

Take 1800g of tert-butyl acetate in 2000ml with stirring in a four-necked flask, and then add 6.8mL catalyst TZB, the reaction flask device has an inner diameter of 15mm height of 800mm precision distillation column, under the protection of N2 heated to 95 ??, to 15ml/min drop acceleration rate to add 409g of 14.1% methanol magnesium methanol solution, at the beginning of the white precipitate. The kettle temperature was 95?? after the dropwise addition was completed, and the distillation temperature at the top of the tower was 57??, at this time, the reflux ratio was set to 1. With the gradual evaporation of methyl acetate and the gradual increase of the kettle temperature, the distillation temperature at the top of the tower was also increased, and the temperature was gradually increased from 57?? to 97??, and at this time, the top of the tower distillation liquid did not contain methyl acetate, and all of it was tert-butyl acetate. At the same time with the gradual increase in the temperature at the top of the tower will be adjusted to 5 reflux ratio, and finally adjusted to 20. When the temperature at the top of the tower stabilized at 97 ?? C for a long time (1 hour), stop the distillation reaction time of about 6 hours. The reaction mixture under N2 protection under reduced pressure filtration, a small amount of tert-butyl acetate to wash the filter cake, and then dry the filter cake under reduced pressure to obtain 100 grams of white porous solid magnesium tert-butanol, the purity of 99.5%.
