⚗️ Chemical & Physical Properties
Dimethyl Disulfide is a colorless liquid with a strong, unpleasant odor similar to that of garlic or onions. This odor is distinctive and easily recognizable even at low concentrations.
The molar mass of Dimethyl Disulfide is approximately 94.20 g/mol, with a density of around 1.065 g/cm^3 at room temperature. In comparison to common food items, Dimethyl Disulfide has a higher molar mass and density than water (18.02 g/mol, 1 g/cm^3) but lower than sugar (342.30 g/mol, 1.59 g/cm^3).
Dimethyl Disulfide has a melting point of -85°C and a boiling point of 109°C. These values are significantly lower than those of common food items such as salt (melting point 801°C) and olive oil (boiling point above 200°C).
Dimethyl Disulfide is poorly soluble in water but has a relatively low viscosity, giving it a thin consistency. Compared to common food items like sugar (high solubility in water) and honey (high viscosity), Dimethyl Disulfide exhibits different solubility and viscosity properties in aqueous solutions.
🏭 Production & Procurement
Dimethyl Disulfide is primarily produced through the reaction between methanol and hydrogen sulfide in the presence of a catalyst. This chemical process typically occurs at high temperatures and pressures to ensure optimal yield of the desired product.
