摘　　要：异丁基铵黑药和正丁基铵黑药是同分异构体,它们有相同的分子式,只烷基异构。根据同分异构的化学原理,有机物有相同的分子式和相同的官能团时,它们的化学性质和物理性质很相似。浮选药剂的浮选性能是它的物理性质和化学性质的集中反映,因此同分异构体的浮选性能亦应十分相似。因此合成原料来源广、价格便宜、易于合成、毒性低的某种浮选药剂的同分异构体,往往能筛选出较好的浮选药剂。本研究合成正丁基铵黑药的同分异构体异丁基铵黑药,并用这两种同分异构体分别作捕收剂浮选铅锌矿矿石,试验结果表明上述论点的正确性。Ammonium di-iso-butyl dithiophosphate and ammonium di-n-butyl dithiophosphate is isobutyl isomers,they have the same molecular formula,only alkyl isomers.According to the principle of isomeric chemistry,when organic substances have the same molecular formula and the same functional groups,their chemical and physical properties are very similar.The flotation performance of flotation reagents are fully affected by its physical and chemical properties,so the flotation performance of isomers should be very similar.Therefore,some sort of flotation reagent＇s isomers with features of wide source,low price,easy to be synthetic,and low toxicity can always filter out the better flotation reagents.In this paper,by synthetizing the isomer of ammonium di-n-butyl dithiophosphate-ammonium di-iso-butyl dithiophosphate and by using these two isomers respectively as collector to make a flotation for lead-zinc ore.The test results show that the argument above mentioned is correct.
