四氯化锡催化合成橙花素

Synthesis of Nerolin Bromelia Catalyzed by Stannic Chloride

四氯化锡能够代替硫酸作为醚化催化剂.在五水四氯化锡存在下,由β 萘酚和乙醇合成了橙花素(β 萘乙醚).当β 萘酚、乙醇和四氯化锡的物质的量比为1:4:0.114,回流反应12h,醚收率达74.4%.

Stannic Chloride can used as catalyst for etherification instead of sulpharic acid. Nerolin bromelia(β-naphthyl ethyl ether)was synthesis from β-naphthol and ethyl alcohol in the presence of stannic chloride perntahydrate. The influence factors of reaction were investigated. The yield of the ether could reach 74.4% under amount of substance ratio of β-naphthol, ethyl alcohol and stannic chloride were 1:4:0.114, reflux reacting for 12h .
