Salicylhydroxamic acid - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | salicylhydroxamic acid is an efficient chelating agent for rare metal oxide minerals, it is applied to the mineral processing of rare metals, and has the advantages of good selectivity and strong collecting power. Salicylhydroxamic acid is mainly used as a collector or extractant for rare earth minerals, copper oxide, lead-zinc oxide, gold ore, kaolin and other organic synthesis intermediates. |
| Use | pharmaceutical intermediates. Chemical analysis of precipitants, reagents for the analysis of bismuth, copper, nickel and copper. Salichydroxamic acid can form stable chelates with metals such as tin, tungsten, rare earth, copper, iron and the like, and form unstable chelates with alkaline earth metals and alkali metals, salicylhydroxamic acid has better selectivity. In particular, when salicylhydroxamic acid is chelated with cassiterite, it can not only form various forms of external salts, but also form different internal salts. Therefore, the selectivity of salicyl hydroxamic acid to tin is strong. The product is usually used with P86 in cassiterite beneficiation, and has a certain foaming property. |
| production method | is obtained by condensation of methyl ortho-hydroxybenzoate and hydroxylamine hydrochloride in the presence of sodium hydroxide, followed by acidification. |
