AB  - Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained from PET recycling and biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the obtained rubber products were tested and compared with those of commercial dioctyl terephthalate (DOTP). TMTS was prepared by simple and efficient one-pot synthesis from dimethylamine, carbon disulfide, potassium cyanide, and ammonium chloride as catalysts in recycled isopropanol/water azeotrope as solvent. In a comparative study, methoxide, ethoxide, iodide, and amide ions were also used. The two-step reaction mechanism of TMTS synthesis involves the oxidation of the amine salt of dimethyldithiocarbamic acid to TMTD by hydrogen peroxide and sulfur elimination from the TMTD disulfide bond. Potassium cyanide appears to be the most efficient nucleophile. The simplicity of operation, mild reaction conditions, solvent recycling, high yields, and applicability to the industrial level are the advantages of this process. Shore hardness, tensile strength, and compression test results of vulcanized blends before and after aging showed similar properties for both accelerators, while somewhat better results were obtained with LA/PG/PET/EG/LA plasticizer.

AB  - This work presents an optimized laboratory procedure for the synthesis of zinc dimethyldithiocarbamate (Ziram) by the reaction of the sodium salt of dimethyl dithiocarbamic acid and zinc sulfate. The reaction of synthesis of the sodium salt of dimethyl-dithiocarbamic acid takes place starting from dimethylamine, carbon disulfide and sodium hydroxide solution. To the prepared acidified aqueous solution of zinc sulphate, a solution of the sodium salt of dimethyl dithiocarbamic acid was added, whereby zinc dimethyldithiocarbamate is formed in the form of a suspension. The suspension is filtered, the filter cake is washed with water to remove the sulfate ion and dried. The structure of the obtained Ziram was confirmed by IR, 1H and 13C NMR and MS instrumental methods, and the purity was determined by the classical analytical method. The obtained product zinc dimethyldithiocarbamate was ground, formulated and used in pomiculture as fungicide under the trade name Ziram.
