⚗️ Chemical & Physical Properties
Dimethyl sulfate is a clear, colorless liquid with a pungent odor that is reminiscent of vinegar or mustard. Its appearance is similar to that of water, but it is distinctly more volatile in nature.
The molar mass of dimethyl sulfate is approximately 126.13 g/mol, while its density is around 1.33 g/cm3. In comparison to common food items, such as sugar with a molar mass of 342.3 g/mol and a density of ~1.59 g/cm3, dimethyl sulfate is notably lighter and less dense.
Dimethyl sulfate has a melting point of around -31.5°C and a boiling point of approximately 188°C. These values are significantly lower than those of common food items, such as butter (melting point ~35-45°C, boiling point ~160-170°C), indicating its propensity for evaporation and volatility.
Dimethyl sulfate is slightly soluble in water, with a solubility of around 2.3 g/100 mL at 20°C. It also exhibits a relatively low viscosity, making it easily pourable. In comparison to common food items, like salt (soluble in water, high viscosity), dimethyl sulfate demonstrates a moderate solubility and viscosity.
🏭 Production & Procurement
Dimethyl sulfate is commonly produced through the reaction of sulfur trioxide (SO3) with methanol (CH3OH) in the presence of a catalyst, such as oleum. This reaction results in the formation of dimethyl sulfate and water as byproducts. The dimethyl sulfate can then be separated and purified through various processes, such as distillation and filtration, to obtain a high-quality product.
Once produced, dimethyl sulfate can be procured through chemical suppliers or manufacturers who specialize in the production of this compound. The chemical is typically transported and stored in sealed containers, such as drums or tanks, to prevent exposure to moisture and air, which can cause degradation. Proper labeling and handling instructions should be provided by the supplier to ensure safe transportation and storage of dimethyl sulfate.
When procuring dimethyl sulfate, it is essential to adhere to strict safety regulations and guidelines set forth by local and international authorities. Protective equipment, such as gloves, goggles, and a lab coat, should be worn when handling the compound to prevent contact with skin and eyes. Proper ventilation and containment measures should also be in place to minimize the risk of exposure and ensure the safe handling of dimethyl sulfate throughout its procurement and use.
⚠️ Safety Considerations
Safety considerations for Dimethyl Sulfate:
Dimethyl Sulfate is a highly toxic and corrosive substance that poses significant risks to human health and the environment. Exposure to Dimethyl Sulfate can occur through inhalation, skin contact, or ingestion. Inhalation of Dimethyl Sulfate can cause severe respiratory irritation, coughing, and difficulty breathing. Skin contact with Dimethyl Sulfate can result in severe burns, blistering, and tissue damage. Ingestion of Dimethyl Sulfate can cause burns in the mouth, throat, and stomach, as well as nausea, vomiting, and diarrhea. Due to its high toxicity, Dimethyl Sulfate should only be handled by trained professionals using appropriate personal protective equipment and safety measures.
Hazard statements for Dimethyl Sulfate:
Dimethyl Sulfate is classified as a highly toxic substance that poses serious risks to human health and the environment. Hazard statements for Dimethyl Sulfate include “Fatal if swallowed,” “Causes severe skin burns and eye damage,” “May cause respiratory irritation,” and “Toxic to aquatic life.” Dimethyl Sulfate should be handled with extreme caution and all necessary precautions should be taken to prevent exposure and minimize the risk of harm.
Precautionary statements for Dimethyl Sulfate:
Precautionary statements for Dimethyl Sulfate include “Do not breathe dust/fume/gas/mist/vapors/spray,” “Wear protective gloves/protective clothing/eye protection/face protection,” “Do not eat, drink, or smoke when using this product,” and “Avoid release to the environment.” It is important to follow all recommended safety measures when working with Dimethyl Sulfate to protect yourself and others from harm. Proper training, adequate ventilation, and appropriate personal protective equipment are essential to ensure safe handling of Dimethyl Sulfate.
🔬 Potential Research Directions
Research on dimethyl sulfate has the potential to explore its application as a reagent in organic synthesis due to its ability to react with a variety of functional groups, leading to the formation of complex molecules.
