摘 要:以对氯苯酚为原料,与异丁烯反应成醚保护羟基,经格氏反应后,通入环氧乙烷得到对叔丁氧基苯乙醇,再经氢溴酸水解得到对羟基苯乙醇。反应总收率69%(以对氯苯酚计),含量≥98.5%。解决了对羟基苯乙酸乙酯还原法成本高及苯乙醇合成法废水量大的问题,具有工业化应用前景。 |

Abstract:p-Chlorophenol was used as the raw material, it reacted with isobutylene to form ether bonds to protect the hydroxyl group, and p-tert-butoxyphenylethanol was obtained through reactions of Grignard reaction and reaction of ethylene oxide. p-tert-Butoxyphenylethanol was then hydrolyzed using hydrobromic acid to obtain p-hydroxyphenylethanol. The total yield was 69% (as p-chlorophenol) and the purity was≥98.5%. This method solved the problems of high cost of produced p-hydroxyphenylacetic acid reduction method and large amount of wastewater from p-phenylethanol synthesis method, and has the prospect of industrial application. |
