黄酸丙腈酯化学名称为S—氰乙基—O—烷基黄原酸酯,简称为黄酸丙腈酯或黄酸氰乙酯。通式:乙黄酸丙腈酯代号OSN—23,丁黄酸丙腈酯代号OSN—43。国外对于这类捕收剂进行过研究,有关专利为美国氰胺公司所有,但还没有作为一种浮选剂商品生产及使用。从1973年开始,我所对这一类捕收剂进行了研究,证明这类化合物对于硫化矿物的浮选活性较高,选择性较好。在各种类型的
The chemical name of yellow acid propionitrile is S-cyanoethyl-O-alkylxanthate, abbreviated as yellow acid propionitrile or cyanoethyl cyanoethyl. General formula: Thionyl propionitrile codenamed OSN-23, Butyroline propionitrile codename OSN-43. Abroad for such collectors were studied, the relevant patents for the United States Cyanamid Company, but not as a flotation agent product production and use. Since 1973, I have studied this class of collectors and proved that these compounds have higher flotation activity and better selectivity for sulfide minerals. In various types
