一、前言近年来,二硫代胺基甲酸盐(dithiocarbamates)和秋兰姆(thiurams)类化合物的分离鉴定方法因纸上色层法之发展有了解决的途径。齐普(zijp)曾将二硫代胺基甲酸盐和秋兰姆用盐酸分解,然后用纸层法分离鉴定生成的仲胺。此法的缺点是:如不同试料分子两端的官能团相同,则生成之仲胺亦相同。故鉴定结果极不可靠。村上等用部分乙酰化的滤纸(乙酰度17.0％)分离此二类化合物,所得R_F值在0.47—0.73之间,故分离效果并不理想。金沢和佐藤以硅油(DC-550)和液体石蜡作反相,该法经笔者验证,所得结果大体相近,但对于二硫代胺基甲酸盐和秋兰姆间
I. Introduction In recent years, the methods for the isolation and identification of dithiocarbamates and thiurams have been solved by the development of paper chromatography. Zijp used dithiocarbamate and thiuram to decompose with hydrochloric acid, and then the secondary amine formed was separated and identified by the paper layer method. The disadvantage of this method is that if the functional groups at the two ends of different sample molecules are the same, then the same secondary amine will be formed. Therefore, the identification results are extremely unreliable. Murakami part of the acetylated filter paper (degree of acetyl 17.0%) to separate these two compounds, the resulting R_F value between 0.47-0.73, so the separation effect is not satisfactory. Kimchi and Sato silicone oil (DC-550) and liquid paraffin phase inversion, the method verified by the author, the results are generally similar, but between the dithiocarbamate and thiuram
