What is tetramethylthiuram disulfide used for?

Chemical synonyms: Tetramethylthiuram disulfide, Bis (dimethyldithiocarbamoyl) disulfide, Thiram, Thiuram TMTD is widely used in rubber processing as an ultra accelerator for low-temperature cures, either alone or as an activator for other accelerators, chiefly the thiazoles. It can be used:

Is thiram a dithiocarbamate?

Thiram is a dithiocarbamate. Some thiurams have been used as rubber components: thiram is used as a rubber accelerator and vulcanizer; a seed, nut, fruit, and mushroom disinfectant; a bacteriostat for edible oils and fats; and as an ingredient in suntan and antiseptic sprays and soaps.

What are the production methods of dimethylamine & carbon disulfide?

Production methods from dimethylamine, carbon disulfide, ammonia condensation reaction was dimethyl dithiocarbamate, and then by the oxidation of hydrogen peroxide to the finished product. Acute oral-rat: LD50 780~865mg/kg; Acute oral-mice: LD50 1500~2000mg/kg. Accelerator T has an irritation effect on the human mucous membrane and skin.

Does thiram cause toxicity?

Toxic effects of thiram have been described in humans and animal model systems ranging from liver injury, testicular toxicity, ophthalmological changes, and development of micronuclei in bone marrow. However, the mechanisms of these effects are not characterized and inconsistent across various studies. Dust may form explosive mixture with air.

How long does thiram degradation last in a non-autoclaved soil?

To a non-autoclaved alluvial sandy loam (pH 7.3) fortified and inoculated with the bacterium Pseudomonas aeruginosa, 40 and 86% degradation were observed after 4 and 24 days, respectively. In autoclaved soil, thiram degradation was not affected.

How is dmdt converted to DMA and carbon disul?

The conversion of DMDT to DMA and carbon disul?de occurred via enzymatic and nonenzymatic mechanisms (Odeyemi and Alexander, 1977). When thiram (100 ppm) was inoculated with activated sludge (30 ppm) at 25°C and pH 7.0 for two weeks, 30% degraded.
