What is tetramethylthiuram disulfide used for?

In rubber industry, Tetramethylthiuram Disulfide can be used as the super-vulcanization accelerator, and aften used with thiazole accelerator. It can also be used in combination with other accelerators as the continuous rubber accelerator. For slowly decomposing out of free sulfur at more than 100 ℃, it can be used as curing agent too.

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.

What is thiram cytotoxicity?

Thiram cytotoxicity appears to result from its potential to disrupt cellular defense mechanisms against oxidative stress. In cultured human skin fibroblast, thiram results in an increase in oxidative markers such as lipid peroxidation and oxidation of reduced glutathione and decrease in other endogenous antioxidant.
