Abstract
In this paper an innovative technological procedures for the production of carbamates (selective flotation reagents) was presented, as well as, some advantages over the classical, known process of production. A technological procedures for the synthesis of thiocarbamate starts with reaction between alkylxanthogens and amines in the presence of nano-palladium multiwall carbon nanotube catalysts, and continues with oxidation of the xanthogenic acid amine salt and catalytic reaction from isobutanol and amine. Obtained results are compared with classical ammonolysis in terms of yield and quality of the obtained products. New technological procedures for the production of carbamates exhibit comparative significant advantages such as mild reaction conditions, higher conversion rate and ecologically justified without the separation of the product.
