Zhang, Jian-feng published the artcilePhase transfer catalyzed synthesis and flotation performance of isomers of biphenoxyl bi(acetic acid), COA of Formula: C10H10O6, the publication is Zhongguo Youse Jinshu Xuebao (2001), 11(4), 707-711, database is CAplus.
In the presence of tributylethylammonium ethylsulfate as a phase-transfer catalyst, three isomers of biphenoxyl bi(acetic acid) (I) are synthesized from biphenol, chloroacetic acid and sodium hydroxide in a chloroform solvent. The flotation depressing performance of I for calcite, diaspore and pyrite was studied. I possesses a depressing ability to the three minerals in the order calcite > diaspore > pyrite. I can be used as an efficient depressant for calcite and diaspore. Electronegativity of the group, reagent specific exponent and HLB of I are discussed. Quantum calculations were done by using the Mopac method on an MSI workstation which explained the depressing mechanism and structure-performance relations of the synthesized flotation depressants.
