Carbon disulphide Uses

 Carbon disulphide (CAS NO.75-15-0) is used frequently as a building block in organic chemistry as well as an industrial and chemical non-polar solvent.

Carbon disulphide Production

 Carbon disulphide (CAS NO.75-15-0) once was manufactured by combining carbon and sulfur at high temperatures. A lower temperature reaction, requiring only 600 °C utilizes natural gas as the carbon source in the presence of silica gel or alumina catalysts.

Carbon disulphide Specification

 Carbon disulphide , its cas register number is 75-15-0. At very high levels, carbon disulfide may be life-threatening because it affects the nervous system. Significant safety data come from the viscose rayon industry, where both carbon disulfide as well as small amounts of H2S may be present. A human poison by unspecified route. Human reproductive effects on spermatogenesis by inhalation. Experimental teratogenic and reproductive effects. The main toxic effect is on the central nervous system, acting as a narcotic and anesthetic in acute poisoning with death following from respiratory failure. Flammable liquid. A dangerous fire hazard when exposed to heat, flame, sparks, friction, or oxidizing materials. Severe explosion hazard when exposed to heat or flame. Ignition and potentially explosive reaction when heated in contact with rust or iron. Mixtures with sodium or potassium-sodium alloys are powerful, shock-sensitive explosives. Explodes on contact with permanganic acid. Potentially explosive reaction with nitrogen oxide, chlorine (catalyzed by iron). Reacts with metal azides to produce shock- and heat-sensitive, explosive metal azidodithioformates.
 Carbon disulphide (CAS NO.75-15-0) is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product: Do not induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water, and get medical aid immediately. Notes to physician: Effects may be delayed. Observe patient.
