选别非硫化矿的有效捕收剂ИМ-50药剂,有碱式的(7-8%的 C7-C9烷基异羟肟酸钠盐水溶液)和酸式的(其主要组成为 C7-C9的异羟肟酸)两种形式的产品。这种药剂可看作含 C7-C9羧酸的混合物,一般羧酸的含量为异羟肟酸重量的10-15%。降低ИМ-50药剂用量的可能方法之一,就是可以把它配制成碳氢化合物的溶液形式使用。众所周知,C6-C10的单一的异羟肟酸,实际上是不溶于石油类的碳氢化合物。但是,试验表明酸式的ИМ-50药剂可以溶解于各种石油类的碳氢化合物——煤油、矿物油、溶剂石 An effective collector of non-sulphide ore, ИМ-50, has a basic (7-8% aqueous solution of C7-C9 alkyl hydroxamate sodium salt) and an acid (consisting essentially of C7-C9 Hydroxamic acid) two forms of product. This agent can be considered as a mixture of C7-C9 carboxylic acids, generally having a carboxylic acid content of 10-15% by weight of the hydroxamic acid. One of the possible ways to reduce ИМ-50 dosage is to use it in the form of a hydrocarbon solution. It is well-known that the single hydroxamic acid of C6-C10 is virtually insoluble in petroleum-based hydrocarbons. However, tests have shown that acid-type ИМ-50 agents can be dissolved in a variety of petroleum hydrocarbons - kerosene, mineral oil, solvent stone
