Description

technical field

[0001] The invention relates to the field of chemical industry, in particular to a preparation method of α-ethylfuranmethanol. technical background

[0002] α-Ethylfuranmethanol is the raw material intermediate of the chemical synthesis method of ethyl maltol. It is usually prepared by Grignard reaction to prepare Grignard reagent, and then it is prepared by addition and hydrolysis of furfural. The Grignard reagent is prepared under the following conditions, and the Grignard reagent is added with furfural at low temperature (about 0°C), and then hydrolyzed to obtain α-ethylfuranmethanol. The reaction formula is as follows:

[0003]

[0004] The process route of this method is long, the reaction pressure and reaction temperature all have special requirements, and the quality of the produced product is relatively unstable. Contents of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a new prep...
