Abstract
The invention relates to a preparation method of high-purity magnesium isopropoxide. The preparation method comprises the following processing steps of: A, synthesizing magnesium methoxide, namely placing methyl alcohol and magnesium into a reaction kettle, carrying out heating reflux until no bubble is produced, so as to generate magnesium methoxide, and then drying methyl alcohol by distillation, so as to obtain magnesium methoxide solid; and B, preparing magnesium isopropoxide by adopting an esterlysis method, namely placing the magnesium methoxide solid and isopropyl acetate into a distillation kettle of the reaction kettle, carrying out fractional distillation in an upper column, and drying by distillation in a double cones, so as to obtain magnesium isopropoxide solid. The preparation method of the high-purity magnesium isopropoxide has the advantages that the preparation method is scientific and reasonable in design, by adopting the esterlysis method, the high-purity magnesium isopropoxide can be prepared, and preparation cost is low.
Description
Technical field
This invention relates to the preparation method field of high purity magnesium isopropoxide.
Technical background
At present, magnesium isopropoxide is as a kind of organic catalyst compound efficiently, broad market prospect, and magnesium isopropoxide is difficult to MAGNESIUM METAL and Virahol directly synthetic.
Summary of the invention
Purpose of the present invention is exactly as a kind of organic catalyst compound efficiently at present magnesium isopropoxide, broad market prospect, magnesium isopropoxide is difficult to the deficiency of directly synthesizing with MAGNESIUM METAL and Virahol, and a kind of preparation method of high purity magnesium isopropoxide is provided.
The preparation method of high purity magnesium isopropoxide, step of preparation process is:
A, synthesizing methanol magnesium:
Methyl alcohol and magnesium are put into reactor, to there not being bubble, generate magnesium methylate through reflux, at evaporate to dryness methyl alcohol again, get solid methanol magnesium;
B, esterlysis legal system are equipped with magnesium isopropoxide:
Solid methanol magnesium and isopropyl acetate are placed still kettle, and last tower fractionation, and oven dry obtain the solid magnesium isopropoxide.
The parts by weight of raw materials proportioning is:
Methyl alcohol 600-1000 magnesium 20 isopropyl acetate 600-1000.
Advantage of the present invention is: this preparation method design science is reasonable, and the esterlysis method can not only be prepared the magnesium isopropoxide of high purity (98%-99%), and the magnesium isopropoxide cost that utilizes this method to prepare is lower.Solvent can be recycled.
Embodiment
A, 600-1000 kilogram methyl alcohol and 20 kilograms of magnesium are put into reactor, be back to no bubble through heating (50-60 ℃), generate magnesium methylate, evaporate to dryness methyl alcohol gets solid methanol magnesium again;
B, esterlysis legal system are equipped with magnesium isopropoxide:
Solid methanol magnesium and 600-1000 kilogram isopropyl acetate are placed still kettle, and last tower fractionation and evaporate to dryness obtain solid magnesium isopropoxide (110-115 kilogram).Yield is more than 97%.
Claims (2)
