产品详情(用途,包装等)
Colorless oily liquid with foul odor, freezing point -7 ℃, boiling point 200-235 ℃ (atmospheric pressure), 165-166 ℃ (5199, 5Pa), explosion range 0.7-9.1% (V/V), flash point 129 ℃, viscosity 5.3 centipoise, specific gravity d20/4 0.854, insoluble in water, soluble in organic solvents such as ethanol, ether, acetone, benzene, gasoline, and esters. Product Name: tert dodecyl mercaptan Foreign name: T-Dodecyl Mercaptan CAS No.:25103-58-6 Molecular formula: C12H25SH Molecular weight: 202.4 Appearance: Colorless liquid Nature: Unique foul odor Melting point: -7.5 ℃ Boiling point: 233 ℃ Density: 0.858-0.860 g/ml Solubility: insoluble in water, soluble in hydrocarbons Usage: Relative molecular weight regulator and chain transfer agent Main purpose Mainly used for ABS resin, styrene butadiene rubber (SBR), nitrile rubber (NBR), high impact polystyrene (M-HIPS) products, and as a molecular weight regulator in the polymerization reaction process. It can also be used as a stabilizer and antioxidant for polyolefins such as polyvinyl chloride and polyethylene, and as a raw material for the synthesis of certain drugs, insecticides, fungicides, and fragrances. Tertiary dodecanethiol (TDDM) is mainly used as a molecular weight regulator in the production of ABS and SBR. At present, the domestic ABS production capacity is 1 million tons per year, SBR production capacity is 500000 tons per year, and TDDM demand is 5000 tons per year. Almost entirely dependent on imports, with high prices.
