黄原酸盐长期被利用于有色金属硫化旷浮选过程中,証明是一良好药剂。許多研究者为了研究浮选药剂对矿物的作用,曾經利用含同位素S~(35)的黄原酸盐,我們也为了同样目的,研究了它的制备,一般黄原酸盐的制法已較成熟,制备标記黄原酸盐的主要困难在于微量操作。佐藤敏郎研究了由含S~(35)的硫酸到黄原酸鉀的合成,瓦西里耶娃研究了由含S~(35)的硫化鈉到黄原酸鉀的合成,黄原酸盐一般都是利用以下反应制取的: ROH+CS_2+KOH→ROCSSK+H_2O 副反应产物可能有,K_2S_2O_3,K_2CO_3,KHCO_3,
Xanthate has long been used in non-ferrous sulphide flotation process, proved to be a good agent. In order to study the effect of flotation reagents on minerals, many researchers have used the xanthate containing isotope S ~ (35). We also studied its preparation for the same purpose. Generally, the preparation method of xanthate Mature, the main difficulty in the preparation of labeled xanthates lies in the minimal amount of manipulation. Sato Toshiro studied S ~ (35) containing sulfuric acid to potassium xanthate synthesis, Vasilyeva from S ~ (35) of sodium sulfide to the synthesis of potassium xanthate, xanthate in general Are prepared by the following reaction: ROH + CS_2 + KOH → ROCSSK + H_2O side reaction products may have, K_2S_2O_3, K_2CO_3, KHCO_3,
