| titleOfInvention | Synthetic method of SPE |
| abstract | The invention discloses a synthetic method of SPE, comprising the following steps: uniformly mixing an organic solvent, dimethylaminoethyl methacrylate and a polymerization inhibitor, and dropwise adding 1, 3-propane sultone into the mixed solution for reaction to obtain a target product; the organic solvent is an alcohol solvent and/or a ketone solvent. The synthesis method of the invention selects the alcohol and/or ketone solvent as the reaction solvent, the solvent has low toxicity and harm, and the alcohol and ketone solvent is easy to recycle and reuse, and is safer and more environment-friendly compared with the method using carbon tetrachloride as the solvent; the dimethyl aminoethyl methacrylate and the 1, 3-propane sultone are used as raw materials, and the polymerization inhibitor is added, so that the polymerization of the dimethyl aminoethyl methacrylate can be effectively inhibited, other side reactions in the reaction process can be reduced, the reaction is more sufficient, and the yield and the purity of the product are improved. |
