以天然植物色素提取物—茜素为原料与烯丙基氯进行Williamson醚化反应并通过两种方式在不饱和醚化产物的双键上引入巯基:(1)通入氯化氢气体加成,再以硫脲对氯化产物进行改性得到巯基改性茜素;(2)Co-Mo/γ-Al2O3催化下,通入硫化氢气体进行马氏规则的烯烃亲电加成反应得到巯基改性茜素。利用红外光谱对上述两种产物结构进行表征后,又将其配制为染发剂试验,结果表明,两种巯基改性的茜素染发效果均达到永久性染发剂标准。
以天然植物色素提取物—茜素為原料與烯丙基氯進行Williamson醚化反應併通過兩種方式在不飽和醚化產物的雙鍵上引入巰基:(1)通入氯化氫氣體加成,再以硫脲對氯化產物進行改性得到巰基改性茜素;(2)Co-Mo/γ-Al2O3催化下,通入硫化氫氣體進行馬氏規則的烯烴親電加成反應得到巰基改性茜素。利用紅外光譜對上述兩種產物結構進行錶徵後,又將其配製為染髮劑試驗,結果錶明,兩種巰基改性的茜素染髮效果均達到永久性染髮劑標準。

Alizarin,a natural plant pigment extract,was used as raw materials to undergo Williamson etherification reaction and bring in sulfhydryl in the double bond of unsaturated etherification product through two ways:(1)aerate hydrogen chloride gas to perform addition reaction,then use thiourea to modify the chlorinated product to get sulfhydryl modified alizarin;(2)under the catalytic of Co-Mo/γ-Al2O3,aerate hydrogen sulfide(gas) to perform the olefin electrophilic addition reaction under Markovnikov's rule to get sulfhydryl modified alizarin.The structure of the above-mentioned two kinds of product was characterized by infrared spectrum.The results of a hair dye test showed that both the two kinds of sulfhydryl modified alizarin dye hair can reach the permanent colourants standard.
