ABSTRACT:
The quality of dialkyl dithiophosphates as flotation promoters is improved by addition to the neutralized acid of small quantities of a trialkyl amine. More important, promoters thus stabilized exhibit markedly increased storage life and substantially no tendency to corrode steel. Shipping and storage of these products is thus facilitated.
