Description

technical field

[0001] The present invention relates to a preparation device of acrylamide crystal, and the present invention also relates to a preparation method of acrylamide crystal. Background technique

[0002] Acrylamide is an important organic chemical raw material with a wide range of uses. There are more than 100 kinds of products synthesized by using it as a unit, among which it is mainly used for the production of polyacrylamide. Polyacrylamide is widely used in various fields such as oil exploration, paper industry, beneficiation, coal washing, metallurgy, water treatment, sugar production, building materials, fabric treatment and chemical industry as a flocculant, thickener, enhancer, etc. Due to the increasingly prominent market potential of polyacrylamide in the above fields, especially the gradual rise of the environmental protection industry, there will be greater demand for polyacrylamide and more acrylamide monomers. Therefore, the acrylamide industry has ...
