  • What is tetramethyl thiuram disulfide?
  • Chemical Name: Tetramethyl thiuram disulfide Molecular Formula: C6H12N2S4 Molecular Weight: 240.41 CAS NO: 137-26-8 Properties: White or light gray powder (granule). The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline and alkali with lower concentration.
  • Is thiuram a fungicide?
  • Thiram is the agricultural name for thiuram. ChEBI: An organic disulfide that results from the formal oxidative dimerisation of N,N-dimethyldithiocarbamic acid. It is widely used as a fungicidal seed treatment. A liquid solution of a white crystalline solid. Primary hazard is to the environment.
  • Does autoclaved soil degrade thiram?
  • 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. Degradat Soil.
  • How long does thiram decompose in acidic media?
  • Thiram is decomposed in acidic media. It deteriorates on prolonged exposure to heat, air or moisture. DT 50 values are estimated as 128 days, 18 days and 9 hours at pH 4, 7 and 9, respectively (PM). The dimethyldithiocarbamate (2) is stable in alkaline media but unstable in acidic conditions, decomposing to dimethylamine and carbon disulfide.
  • What is the pH value of thiram?
  • The reaction temperature is 50~55℃ and the pH value is 8~9. The preparation of thiram: the reaction of SDD (or Diram) and hydrogen peroxide in the presence of sulfuric acid can produce thiram. The reaction temperature is controlled at 10 ℃ below and the end pH value is 3 to 4.
  • What happens if Thiram is inoculated with activated sludge?
  • When thiram (100 ppm) was inoculated with activated sludge (30 ppm) at 25°C and pH 7.0 for two weeks, 30% degraded. Metabolites included methionine, elemental sulfur, formaldehyde, dimethyldithiocarbamate-α-aminobutyric acid and the corresponding keto aci
