摘要： There is described a process for the separation and purification of the platinum group metals from base metal out of acidic aqueous solutions. For this purpose there is used a substituted thiourea of the formulaR.sub.1 R.sub.2 N--CS--NH--CO--R.sub.3orR.sub.1 R.sub.2 N--CS--NH--COOR.sub.3as the extraction agent. Preferably there are employed N,N-dialkyl-N'-benzoylthiourea wherein R.sub.1 and R.sub.2 are methyl, n-butyl, or n-hexyl.

摘要： Residues are formed in the carbonylation of esters or ethers, particularly in the production of acetic anhydride or ethylidene diacetate. When such residues contain noble metal, typically rhodium, used as a catalyst, the noble metals must be recovered before the residues can be disposed of. The metal values are freed from the residues by treatment with amines, thereby enabling the rhodium to be extracted by subsequent contact with an aqueous halogen acid. The residues are pretreated with alkanols and concentrated by evaporation to improve the effect of such amine treatments.
