Abstract

The invention discloses a method for synthesizing glyceryl butanone acrylate, which comprises the following steps of: in an esterification reaction kettle, carrying out ester exchange reaction on glyceryl butanone and methyl acrylate under the action of a catalyst and a polymerization inhibitor, heating, refluxing and condensing; collecting reflux liquid, adding the reflux liquid into a water knockout vessel filled with glycerol, violently stirring to promote the glycerol to fully absorb the generated methanol, then standing until the mixed liquid is layered, adding the separated methyl acrylate into the esterification reaction kettle again for reaction, and circulating and repeating until the conversion rate of the glycerol butanone is constant; removing the methanol in the glycerol which absorbs the methanol, and collecting the glycerol; and removing methyl acrylate in the reaction liquid under reduced pressure to obtain glyceryl butanone acrylate.

Description

Technical field [0001] The present invention belongs to the field of synthesis of the photo-curable reactive diluent, particularly relates to a method for synthesizing glycerol acrylate butanone. Background technique [0002] In May 2004, held in Charlotte, North America International Conference on radiation curing, UV curing and electron beam curing technology has been summarized as "5E" technical features, that is efficient (efficient), adaptability (enabling), economy (economical), energy conservation (energy saving) and environment-friendly (environmental). Usually a UV curable material reactive oligomers, reactive diluents and photoinitiators and other additives. Under ultraviolet light, the photoinitiator generates radicals or cations instantaneously, triggering reactive oligomers and reactive diluents in situ polymerization. The process is very fast, is the variety of inks, adhesives, paint dried the fastest. Light-cured product may be cured rapidly at room temperature, th...
