chloroform

1.It was soon replaced by chloroform.

不久它被氯仿所代替。

2.chloroform; formaldehyde; methylene chloride; methyl chloride; para ldehyde; formic acid; chloroacetaldehyde.

氯仿,甲醛,氯化次甲基,氯甲烷,三聚醛,甲酸,氯醛

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、醇、氯仿、丙酮、醚。

4.However, chlorin will interact with the organics remained in the water and form halohydrocarbon, chloroform and other cancer-causing toxic compounds.

但同时，氯与水中残留的有机物用，会形成卤代烃、氯仿等有毒的致癌化合物。

5.Methods:Chloroform being solvent,under bath heat,4 hydroxymethyl caged bicyclic phosphate acylated with pentanoyl chloride and hexanoyl chloride dividedly.

方法:用氯仿溶剂,在浴温条件下,4羟甲基笼状双环磷酸酯分别与戊酰氯、己酰氯发生酰化反应。

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.

以甲醇、氯仿、石油醚为提取溶剂,提取中药材海金沙得到海金沙不同溶剂提取物,采用红外光谱(FT-IR)图谱鉴别法对提取物进行实验。

7.Results: Among the methods suitable for alkaloid extraction, the solvent ether chloroform 95% ethanol (25∶8∶2.5) is the best for imperialine extraction.

结果:在适宜于生物碱提取的常用方法中,以醚氯仿95%醇(25∶8∶2。
