Flammable liquids carbon disulfide

Disposal of 2 1 of the solvent into a rusted iron sewer caused an explosion. Initiation of the solvent-air mixture by rust was suspected [1], A hot gauze falling from a tripod into a laboratory sink containing some carbon disulfide initiated two explosions [2], It is a very hazardous solvent because of its extreme volatility and flammability. The vapour or liquid has been known to ignite on contact with steam pipes, particularly if rusted [3], When a winchester of the solvent fell off a high shelf and broke behind a rusted steel cupboard, ignition occurred [4],... 

Carbon disulfide is an extremely flammable liquid, the closed cup flash point being -22°F (-30°C). Its autoignition temperature is 90°C (194°F). Its vapors form explosive mixtures with air, within a wide range of 1.3 to 50.0% by volume in air. Reactions with certain substances can progress to explosive violence. They include finely divided metals, alkali metals, azides, fulminates, and nitrogen dioxide.

CARBON BISULFIDE Carbon Disulfide Flammable liquid, I 2 3 0 ... 

CARBON DISULFIDE. [CAS 75-15-0. Carbon disulfide (carbon bisulfide, dithiocarbonic anhydride), CS . is a toxic, dense liquid of high volatility and flammability. It is an important industrial chemical and its properties arc well established. Low concentrations of carbon disulfide naturally discharge into the atmosphere from certain soils, and carbon disulfide has been delected in mustard nil. volcanic gases, and crude peiroleum. Carbon disulfide is an unintentional by-produci of many combustion and high temperature industrial processes where sulfur compounds are present. 

Carbon disulfide (CS2) is a highly flammable, volatile, and extremely foulsmelling liquid that causes a burning sensation on the skin. It can produce psychic and visual disturbances as well as nausea, vomiting, and convulsions. Typically carbon disulfide is used as a solvent for substances such as sulfur or phosphorus. There are other solvents (the methylene halides or the xylenes, for example) that would be more pleasant to work with and much less hazardous. 

The yellow color of commercial carbon disulfide is due to the presence of small amounts of dissolved sulfur. The rather disagreeable odor of this material is also due to the presence of impurities. Carbon disulfide is a highly flammable liquid which is very poisonous and which is only very slightly soluble in water. 

The large-scale uses of carbon disulfide center mainly about its properties as a solvent. Many fats, oils, waxes, and resins are abundantly soluble in this liquid. Despite the disadvantages attendant upon its volatility, flammability, and toxicity, carbon disulfide is used extensively as a solvent and in processes for the manufacture of rubber products, lacquers, varnishes, cellophane, and so forth. Because of its toxicity, this compound is used to some extent as an insecticide and as a poison for rodents. 

Carbon tetrachloride is colorless, heavy, non-flammable liquid with a characteristic odor. It has a boiling point of 78 Celsius, and a melting point of -23 Celsius. Carbon tetrachloride is insoluble in water, but miscible with alcohol, benzene, chloroform, ether, and carbon disulfide. Carbon tetrachloride is a potential poison, and inhalation, ingestion, and skin absorption should be avoided at all cost. Carbon tetrachloride may be a carcinogen. It is prepared on an industrial scale by the chlorination of methane, but can be conveniently prepared by reacting chlorine with carbon disulfide in the presence of iron fillings the carbon tetrachloride is recovered by distillation. 

Sulfur chloride forms a non-flammable, light amber to yellowish red, fuming oily liquid, which has a penetrating odor. It has a melting point of-77 Celsius, and a boiling point of 138 Celsius. It is soluble in alcohol, ether, carbon disulfide, toluene, carbon tetrachloride, and many oils. It reacts with water yielding sulfur dioxide, hydrogen chloride, and other products. Over exposure... 

When we pour carbon disulfide, a colorless, flammable hquid, on the sulfur sample, the solid sulfur disappears, and the liquid turns yeUow. The sulfur has dissolved, forming a solution with the carbon disulfide. When we pour carbon disulfide on the iron, nothing happens the iron stays solid, and the liquid stays colorless. If we had large pieces of each element, we could pound them with a hammer and find that the sulfur is brittle and easily powdered but that the iron does not easily break into small pieces. Iron is malleable—that is, it can be pounded into various shapes. Table 1.2 lists the properties discussed so far of the two elements.
