查询词典 mercapto

In order to find active pesticide leading compounds, thinking about that triazolothiadiazoles had various biological activities, this paper designed and synthesized 11 novel title compounds from 3-substituted-4-amino-5-mercapto-1,2,4-triazoles with heterocyclic carboxylic acid via cyclization in the presence of phosphoryl chloride by the princple of combination of active strucural moieties. The structures of the title compounds were characterized by melting point, IR, 1HNMR and elemental analysis.

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.
