⚗️ Chemical & Physical Properties
Silane is a colorless gas with a pungent odor, reminiscent of rotten eggs. It is highly flammable and reactive, making it a potentially dangerous substance to handle without proper precautions.
With a molar mass of 32.12 g/mol and a density of 1.38 kg/m^3, Silane is significantly lighter than common food items such as sugar (180.16 g/mol) and water (1,000 kg/m^3). Its low molar mass and density contribute to its highly volatile nature.
Silane has a melting point of -185.5°C and a boiling point of -112.8°C, indicating its extreme volatility compared to common food items like butter (melting point of 32-35°C) and water (boiling point of 100°C). Its low melting and boiling points make it easily vaporizable.
Silane is not soluble in water and has a very low viscosity, distinguishing it from common food items that are typically soluble in water and have higher viscosity levels. Its lack of water solubility and low viscosity make it less similar in behavior to food items in liquid form.
🏭 Production & Procurement
Silane, a key precursor in the production of silicones and other silicon-containing compounds, is primarily produced through the hydrolysis of silicon tetrachloride in the presence of water and a reducing agent. This reaction yields silane gas, which must be carefully controlled and purified to prevent pyrophoricity, a property that renders the gas highly flammable upon contact with air.
Silane gas is typically procured through the chemical industry, where it is commonly produced in large quantities for commercial use. It is often supplied in compressed gas cylinders or in bulk liquid form for transportation to various manufacturing facilities. Due to its flammable nature, transportation of silane must adhere to strict safety protocols to prevent accidents or exposure to potential hazards.
In order to ensure safe handling and transportation of silane, specialized equipment and trained personnel are required to manage the gas effectively. Storage facilities must be equipped with proper ventilation systems and fire suppression measures to prevent accidents. Additionally, procedures for leak detection and emergency response must be in place to mitigate any potential risks associated with the storage and handling of silane gas.
⚠️ Safety Considerations
Safety considerations for Silane, a colorless, flammable gas with a strong, repugnant odor, are paramount due to its highly reactive nature. Silane can react violently with air, water, or most organic substances, posing a significant risk of fire or explosion. Proper storage and handling of Silane requires specialized equipment to prevent inadvertent reactions and release of the gas. Additionally, Silane should only be used in well-ventilated areas to avoid exposure to the gas, which can cause respiratory irritation and may be fatal if inhaled in high concentrations.
Hazard statements associated with Silane include highly flammable gas, may react violently with oxidizing agents, water, or air, and can form explosive mixtures with air. Silane is extremely reactive and may ignite spontaneously at room temperature, making it a severe fire and explosion hazard. Inhalation of Silane may cause dizziness, headache, and respiratory irritation, while skin and eye contact can lead to burns and severe irritation. Exposure to high concentrations of Silane may result in significant health issues, including lung damage and potential fatality.
Precautionary statements for handling Silane include ensuring proper ventilation in the work area, wearing suitable protective clothing, and using only explosion-proof equipment to prevent ignition sources. It is crucial to handle Silane with care, avoiding contact with water, oxidizing agents, or any incompatible materials to prevent hazardous reactions. In the event of a spill or leak, immediate evacuation of the area is necessary, and containment measures should be taken to prevent further release of the gas. Proper training and education on the safe handling and storage of Silane are essential to minimize the risk of accidents and ensure the safety of personnel.
