| titleOfInvention | The synthetic method of double cyclopentenyl oxygen ethylmethyl acrylate |
| abstract | The invention discloses a kind of synthetic methods of double cyclopentenyl oxygen ethylmethyl acrylate.Step is as follows：Methacrylic acid lower alkyl alcohol ester, ethoxy double cyclopentenyl ether, polymerization inhibitor and catalyst are stirred and heated in reactive distillation integrated apparatus；With the progress of reaction, the lower alcohol of generation and the azeotropic mixture of unreacted methacrylic acid lower alkyl alcohol ester is distilled off；After reaction, then Filtration of catalyst distills filtrate decompression to obtain double cyclopentenyl oxygen ethylmethyl acrylate.Polymerization inhibitor used has more significant polymerization inhibition effect, and the polymer object generated in reaction significantly reduces；Used catalyst has many advantages, such as that inexpensive, stability is good, filtering is simple, recycling is convenient；The advantages of Exchange Ester Process is fast, and operation is easy, and product purity is high, stability is good；Product purity reaches more than 98%, with alcohol meter yield more than 85%. |
