12/11/2023 0 Comments Carbon tetrachloride price![]() It has a water solubility of 1160 mg/l and is miscible with various organic solvents. It is toxic and forms phosgene, hydrogen chloride, and chlorine when heated. However, carbon tetrachloride, at high temperature (500 ℃ above), can react with water to produce highly toxic phosgene, so we should pay attention to ventilation for extinguishing fire.Ĭarbon tetrachloride is a clear, colorless liquid with a distinctive, sweet ether-like odor. It is especially suitable for extinguishing oil fire and fire near the power. When the carbon tetrachloride is heat to be evaporated to become heavy steam, the gas will cover the combustion products, so that the firing product is isolated from the air and the fire is extinguished. ![]() Carbon tetrachloride is volatile with its vapor being heavier than air, being non-conductive and inflammable. Therefore, the operator should pay special attention. However, long-term exposure to carbon tetrachloride will irritate the skin, inhibit the central nervous system and cause damage to the liver and kidney. It can also be used as dry cleaning agent. It can dissolve grease, paint, resin, rubber and many other substances, being commonly used organic solvent and extractant. It appears as colorless liquid with the melting point of-23 ° C, boiling point of 76.8 ° C and the relative density of 1.5867.
