Abstract

The invention relates to a technique for producing lithium alkoxide, which is characterized by comprising the following steps: adding lithium metal into a reactor, dripping ethanol slowly at a temperature of between 20 and 30 DEG C, providing ice water outside the reactor to reduce reaction temperature to between 60 and 80 DEG C in a reaction process, and after finishing dripping the ethanol, keeping the temperature to make full reaction to obtain liquid lithium alkoxide; and then conveying the liquid lithium alkoxide to a closed drier, condensing and drying the liquid lithium alkoxide to obtain solid lithium alkoxide. Reaction of the liquid lithium alkoxide is finished in the reactor firstly, and then materials are conveyed to the drier to be condensed and dried so as to obtain the solid lithium alkoxide. The technique is suitable for industrialized production of lithium methoxide, lithium ethoxide, lithium n-butylate, lithium tert-butylate, lithium isopropoxide or other lithium alkoxides; and the obtained product has high purity.

Description

technical field

[0001] The invention belongs to the production technology of chemical products, in particular to a production process of lithium alkoxide. Background technique

[0002] Lithium methoxide, lithium ethoxide, lithium n-butoxide, lithium tert-butoxide, lithium isopropoxide, used in medicine, chemical industry, organic synthesis, phase transfer catalyst, oxyacid inhibitor (used), basically not seen in the market High-purity (content: ≧98%) solid product. Since the reaction between alcohol and metal lithium is an instantaneous reaction, generally the reaction is completed in 1-15 minutes, and a large amount of hydrogen and heat are released during the reaction, which is easy to catch fire and explode, which is very dangerous, so that the product is not easy to achieve industrial production. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a production process of lithium alkoxide, industrialized producti...
