苯乙烯膦酸是近十年来被广泛研究的锡石捕收剂。1970年以来,东德、南非和苏联先后在生产中采用膦酸类作为捕收剂浮选锡石。我所于1972年开展苯乙烯膦酸合成的研究,并于1974年在上海彭浦化工厂进行年产30吨规模的工业试验,验证和完善了实验室的合成条件和工艺流程,生产了部分产品。与此同时,在有关单位的支持下,对它的应
Styrene phosphonic acid is a cassiter collector widely researched in recent ten years. Since 1970, East Germany, South Africa and the Soviet Union successively used phosphonic acids as collector flotation cassiterites. In 1972, I started the research on styrene phosphonic acid synthesis, and in 1974, Shanghai Pengpu Chemical Plant with an annual output of 30 tons of industrial tests to verify and perfect the laboratory synthesis conditions and processes, the production of some products . At the same time, with the support of the relevant units, its response to it
