Abstract
A compound having an empirical formula corresponding to dilauryl dihydrogen hypophosphate is prepared by treating ethyl acetate with molten white phosphorus and then adding lauryl alcohol gradually during 3 1/2 hours while air is bubbled through, the temperature being maintained between 28 DEG and 32 DEG C. Instead of lauryl alcohol, oleyl alcohol may be used to prepare a compound having an empirical formula corresponding to dioleyl-hypophosphate. A further compound having an empirical formula corresponding to di-2-ethyl-hexyl hypophosphate may be prepared by substituting 2-ethyl-hexyl alcohol for lauryl alcohol.ALSO:Natural siliceous heavy mineral ores are separated by froth flotation into a non-floated heavy mineral fraction and a floated siliceous fraction using, as activator, a mineral acid and, as collector, a compound or a mixture of compounds of the formula: Ra Hb Pc Od, in which R is an alkyl group linked to an oxygen atom and a, b, c and d are integers having the values a = 1 to 4; b = 4 - a; c = 1 or 2; and d = 3 to 7, provided that, where d = 3 or 4, c = 1, a = 1 to 3 and b = 3 - a. The mineral acid preferred is H3 PO4 but H2SO4 is mentioned. The collector used may have an empirical formula corresponding to that of a diester of hypophosphoric acid and may also contain esters of phosphorous acid, phosphoric acid and iso-hypophosphoric acid. Collectors mentioned include alkyl phosphite and alkyl phosphates and a number are quoted in examples describing processes for separating minerals from glass sand, beach sand and various siliceous ores. Examples of minerals separated are given. The preparation of specific collectors (see Division C2) is described.
