Abstract

The invention discloses a method for synthesizing trioxymethylene, wherein, formalin solution is taken as reactant and acidic ionic liquid is taken as a catalyst, and the dosage of the catalyst is 0.01-10% by weight.

Description

technical field The invention relates to a method for catalyzing and synthesizing paraformaldehyde from an aqueous formaldehyde solution through an acidic ionic liquid. Paraformaldehyde is an industrial raw material, especially an important raw material for the manufacture of polyoxymethylene resin and a bulk organic chemical raw material to replace formaldehyde. Background technique Paraformaldehyde is a white crystal with stable properties. It is used as a stabilizer, fumigant, insecticide, molding material, adhesive, disinfectant, antibacterial, etc. in color photos. It can be depolymerized to generate formaldehyde, so it can be used in almost all formaldehyde reactions, especially when anhydrous formaldehyde is required as a reactant, its application is more valuable. At the same time, paraformaldehyde is the monomer raw material for the synthesis of polyoxymethylene, which is one of the world's three major general-purpose engineering plastics and the only excellent mat...
