| titleOfInvention | The preparation method of chloroethyl positive propyl ether |
| abstract | The invention belongs to technical field of organic synthesis, and in particular to a kind of preparation method of chloroethyl positive propyl ether.The present invention uses efficient nucleophilic catalyst, using 2 positive propoxy ethanol and thionyl chloride as primary raw material, by the way that thionyl chloride is added dropwise, strict control reaction rate, obtains crude product, then obtains chloroethyl positive propyl ether through rectification and purification by heating, insulation, product appearance is as clear as crystal, purity is up to more than 99.2%, and yield is more than 98.5%, and water content is less than 0.2%.Compared with traditional handicraft, the present invention is produced without waste water, and rectifying evaporates before producing can be recycled with bottom material and catalyst, and purity and high income, water content are low, be adapted to industrialized production. |
