摘要
以柚皮苷为原料制备了柚皮苷二氢查耳酮。考察了反应时间、催化剂用量、反应温度、反应压力、搅拌速度等因素对柚皮苷二氢查耳酮收率的影响。实验结果表明,制备柚皮苷二氢查耳酮优化反应条件为:pH值为13,反应温度45℃,反应时间6 h,氢气压力0.5 MPa,雷尼镍(用量为柚皮苷质量的7%)为催化剂,此条件下收率达90.0%。
The process for preparation of naringin dihydrochalcone from naringin was investigated.The product was obtained in 90% yield under optimum conditions of pH 13,temperature 45℃,H2 pressure 0.5 MPa,raney nickel loading 5%,and reaction time 4 h.
