4.Molecular Weight: 485
5.Physical &Chemical Properties:
This products is yellowish or transparent liquid with a bit ethanol odour, soluble with some kinds of solvents such as ethanol,acetone,benzene, toluene, non-soluble with water, but easily dissolved in connection with water or moisture gas.
6.Technical Index:
Sulfur Content: 15% -16%
Ethanol Content: ≤0.5%
γ2 Content:≤3.0%
Impurity Substance Content:≥1.0%
Viscosity(γ20℃): ≤ 11.0
