Understanding Butyltin Trichloride: Properties, Safety, and Industrial Handling
Butyltin Trichloride (CAS 1118-46-3) is a chemical compound with distinct properties that dictate its industrial applications and handling requirements. Understanding these characteristics is fundamental for ensuring safe and effective utilization. This article aims to provide a comprehensive overview of Butyltin Trichloride's physical and chemical properties, along with essential safety protocols and handling guidelines, from the perspective of a chemical supplier in China.
Physically, Butyltin Trichloride is typically described as a yellowish oily liquid. Its molecular formula is C4H9Cl3Sn, and it possesses a molecular weight of approximately 282.18 g/mol. Key physical properties include a density of around 1.71 g/ml at 25°C and a boiling point of approximately 227°C (though often discussed at reduced pressure, e.g., 102°C at 12 mm Hg). Its flash point is around 81°C (closed cup), classifying it as a combustible liquid. While it has slight solubility in water, it is generally soluble in organic solvents, which is characteristic of many organometallic compounds.
Chemically, Butyltin Trichloride is known for its reactivity. It can hydrolyze in the presence of moisture, releasing hydrochloric acid, which is corrosive. This characteristic necessitates storage under a dry, inert atmosphere, such as nitrogen, to maintain its stability and prevent degradation. It is also incompatible with strong acids, strong bases, and strong oxidizing agents, all of which can lead to hazardous reactions. Upon thermal decomposition or combustion, it can release toxic and irritating fumes, including hydrogen chloride, carbon monoxide, and tin oxides. These chemical behaviors underscore the importance of appropriate handling and storage conditions.
Safety is paramount when working with Butyltin Trichloride. It is classified as harmful if swallowed, inhaled, or absorbed through the skin. Direct contact can cause severe skin burns and eye damage, and inhalation may lead to respiratory irritation or more severe effects. Due to its potential for causing genetic defects and reproductive toxicity, as well as damage to organs through prolonged or repeated exposure, stringent personal protective equipment (PPE) is required. This includes chemical-resistant gloves, eye protection (safety goggles or face shield), and appropriate respiratory protection if ventilation is inadequate. Working in a well-ventilated area or under a fume hood is essential.
Handling procedures must emphasize minimizing contact and preventing exposure. Empty containers can retain hazardous residues and should be handled with the same care as filled containers. Sources of ignition should be kept away, and containers should be kept tightly closed when not in use. From a supplier's perspective in China, ensuring that customers are fully informed about these properties and safety requirements is a priority. Providing clear Material Safety Data Sheets (MSDS) and technical guidance helps users implement safe handling practices, thereby mitigating risks associated with this industrially significant chemical.
