| titleOfInvention | Preparation method of glycidyl acrylate |
| abstract | The invention discloses a preparation method of glycidyl acrylate. According to the preparation method, the reactants are acrylic acid and epoxy chloropropane, the catalyst is triethylamine, and the polymerization inhibitor is p-hydroxyanisole. The preparation method comprises the following steps: mixing the polymerization inhibitor, catalyst and reactants, dispersing, and heating to react, wherein under the action of the p-hydroxyanisole, the epoxy chloropropane and triethylamine are subjected to nucleophilic substitution reaction to generate ammonium chloride, and the acrylic acid and carbon positive cations in the ammonium chloride are subjected to esterification reaction to generate the glycidyl acrylate. The product conversion rate is high, however, the production technique consumes fewer raw materials, the operational process is simple and does not need after treatment, and thus, the invention has high economic benefit and social benefit. |
