Anwendungen & Verwendung
Beschreibung
Dithiocarbamates (DCs) are a well-known group of pesticides which have been used to control a number of species belonging to taxonomically different groups, e.g., bacteria, fungi, nematodes, and molluscs for over 60 years. The first integrated product containing sodium dimethyldithiocarbamate (SDMC) was registered in 1949.
Verwenden
Sodium dimethyldithiocarbamate(SDMC) is used as a disinfectant, corrosion inhibitor, coagulant, vulcanizing agent, chelating agent, and fungicide. SDMC is used in water treatment, the rubber industry, and is a registered biocide for cutting oils and aqueous systems in industries such as leather tanning and paper manufacturing. It is also used as an antimicrobial agent in paints. generally SDMC are able to function as metal chelators and have been used in metal finishing operations and wastewater treatments to enhance the precipitation of metals. As a free radical inhibitor, it has been used in the rubber industry to rapidly stop the polymerization of synthesis. It is also used as a biocide for cutting oils and aqueous systems such as leather tanning and paper manufacturing.
Herstellung & Synthese
synthetische
Sodium dimethyldithiocarbamate is prepared by combining dimethylamine with carbon disulfide in a solution of sodium hydroxide, forming the water-soluble dithiocarbamate salt.
