What is TMTD used for?

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: In conjunction with accelerators such as mercaptobenzothiazole (0.25 – 0.5 TMTD on the weight of the gum).

How to store dimacit TMTD?

Inorganic acids break down Dimacit TMTD into carbon disulfide and hydrogen sulphide. Store in dry well-ventilated place away from foodstuffs. No reduction in the assay of the active substance has been observed after storage for 2 years in the original packing under normal conditions. Protect against acids and substances liberating acids.

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.

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.
