Abstract
Thiopyrimidines are prepared by the condensation of thiourea or a mono-substituted thiourea with an alpha, beta unsaturated ketone. 2 - Mercapto - 6 - methyl - 3,4 - dihydro - pyrimidine is obtained from 3-butane-2-one; 4-mercapto-4,4,6-trimethyl-3,4-dihydropyrimidine from mesityl oxide, acetone or diacetone; 2 - mercapto - 4,6 - dimethyl - 4 - (beta - carboxyl - ethyl) -5-carboxymethyl-3,4-anhydropyrimidine from levulinic acid; 2-mercapto-4-methyl-4,6-diphenyl - 3,4 - dihydropyrimidine from aceto - phenone; 2-mercapto-4,6-dimethyl-4-benzyl-5-phenyl - 3,4 - dihydropyrimidine from phenyl acetone and 2-mercapto-4,4-pentamethylene-5,6-tetramethylene-3, 4-dihydropyrimidine from cyclohexanone or cyclohexylidene cyclo - hexanone. U.S.A. Specifications 2,131,790, 2,181,217, 2,234,848 and 2,244,547 are referred to.ALSO:In a froth flotation process the flotation is carried out in the presence of a thiopyrimidine. Suitable thiopyrimidines are 2-mercapto-4 4, 6-trimethyl-3 4-dihydropyrimidine, 2-mercapto-6-methyl-3, 4-dihy dro pyrmidines; 2-mercapto-4, 6-dimethyl-4-(beta-carboxyl ethyl)-5 carboxyl methyl 3, 4-dihydropyrimidine; 2-mercapto-4, 6-dimethyl-4 - (beta-acetyl ethyl)-5-acetonyl-3, 4 - dihydropyrimidine; 2 - mercapto-4-methyl-4, 6-diphenyl-3, 4-dihydropyrimidine; 2-mercapto-4, 6-dimethyl-4-benzyl-5 phenyl-3, 4-dihydropyrimidine 3 and 2-mercapto-4, 4-penta-methylene-5, 6-tetramethylene-3, 4-dihydropyrimidine. These reagents are suitable for use with sulphide ores and lead, zinc and iron sulphides may be separated in lead-zinc-iron sulphide ores by selectively floating lead sulphide and then selectively floating zinc sulphide in the lead tailing in the presence of this pyrimidine. U.S.A. Specifications 2,131,790, 2,181,217, 2,234,848 and 2,244,547 are referred to.
