| titleOfInvention | A kind of preparation method of cyclopropyl acethlene |
| abstract | The present invention relates to a kind of preparation methods of cyclopropyl acethlene, include the following steps: that 1) cyclopropyl methyl ketone, chlorinating agent, organic base and catalyst are dissolved in organic solvent, under the conditions of 0 DEG C~150 DEG C, it is stirred to fully reacting, distillation purifying, chlorine cyclopropyl ethylene is made, wherein cyclopropyl methyl ketone: chlorinating agent: the molar ratio of organic base is 1:1~5:1~10；2) by chlorine cyclopropyl acethlene and alkali soluble in organic solvent, under the conditions of 0 DEG C~150 DEG C, be stirred to fully reacting, distillation purifying, cyclopropyl acethlene be made, wherein chlorine cyclopropyl ethylene: the molar ratio of alkali is 1:1~10.Organic base used in preparation method of the present invention, catalyst, solvent have the characteristics that safety and environmental protection, reaction condition is mild, it is not related to high temperature, low temperature, without using toxic phosgene, not stringent is required to the airtightness of reaction vessel, and recycle reaction solution, be not related to the processing of a large amount of phosphorus-containing wastewaters, have many advantages, such as high income (89%), at low cost, reliable and stable, Environmental Safety, it is easy to operate, be suitble to industrialized production. |
