2.Methods Galangin was extracted with ethanol, degreased with ligarine, and extracted with chloroform.
方法采用乙醇提取,石油醚脱脂,萃取,上聚胺柱得到高良姜素。
3.It dissolves in hot grease, paraffine, ethanol, chloroform, acetone and aether, but is insoluble in water.
该产品不溶于水,热溶于油脂、石蜡、乙醇、、丙酮、乙醚。
4.Chloroform being solvent,under bath heat,4 hydroxymethyl caged bicyclic phosphate acylated with pentanoyl chloride and hexanoyl chloride dividedly.
用作溶剂,在浴温条件下,4羟甲基笼状双环磷酸酯分别与、己发生化反应。
5.However, chlorin will interact with the organics remained in the water and form halohydrocarbon, chloroform and other cancer-causing toxic compounds.
但同时,与水中残留的有机物相互作用,会形成卤代烃、等有毒的致癌化合物。
6.Different solvent extractions of Spora Lygodii were obtained using methanol,chloroform and petroleum ether as medium.Experiments were carried out on them by FT-IR spectra.
