CARBONYL SULFIDE Chemical Properties,Uses,Production

Chemical Properties

colourless gas with an unpleasant smell; cylinder

Chemical Properties

Carbonyl sulfide is a colorless gas or cold liquid.

Uses

carbonyl sulfide is use as a fumigant for durable commodities and structures was patented worldwide by Australia in 1992. It is effective on a wide range of pests, including the common stored product species at reasonable concentrations (less than 50 gm-3) and exposure times (1-5 days) . However, the egg stage of several insects showed tolerance to the fumigant. The other problems associated with the use of carbonyl sulfide include its high tainting odour on the treated products and reduction in the germination of seeds. Hydrogen sulphide, an impurity, present in fumigant product supply was reported to be responsible for the off-odour problem. Selective removal of hydrogen sulphide using absorbents like tertiary amine may solve the tainting issues with this fumigant.

Uses

Grain fumigant.

Definition

ChEBI: A one-carbon compound in which the carbon atom is attached to an oxygen and a sulfur atom via double bonds.

General Description

CARBONYL SULFIDE is a colorless, poisonous, flammable gas with a distinct sulfide odor. The gas is toxic and narcotic in low concentrations and presents a moderate fire hazard. Under prolonged exposure to fire or intense heat the container may rupture violently or rocket. CARBONYL SULFIDE is used in the synthesis of organic thio compounds.

Air & Water Reactions

Highly flammable.

Reactivity Profile

CARBONYL SULFIDE is expected to react with vigor with strong oxidants.

Hazard

Narcotic in high concentrations. Flammable, explosive limits in air 12–28.5%. Central nervous system impairment.

Health Hazard

TOXIC; may be fatal if inhaled or absorbed through skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.

Fire Hazard

Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard.

Safety Profile

Poison by intraperitoneal route. Mildly toxic by inhalation. Narcotic in high concentration. An irritant. May liberate highly toxic hydrogen sulfide upon decomposition. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, stop flow of gas or use CO2, dry chemical, or water spray. When heated to decomposition it emits toxic fumes of CO. See also CARBONYLS and SULFIDES.

Potential Exposure

Carbon oxysulfide is an excellent source of usable atomic sulfur, therefore, it can be used in various chemical syntheses, such as the production of episulfides, alkenylthiols, and vinylicthiols. It is also used to make viscose rayon. It is probable that the largest source of carbon oxysulfide is as a by-product from various organic syntheses and petrochemical processes. Carbon oxysulfide is always formed when carbon, oxygen, and sulfur, or their compounds, such as carbon monoxide; carbon disulfide, and sulfur dioxide, are brought together at high temperatures. Hence, carbon, oxysulfide is formed as an impurity in various types of manufactured gases and as a by-product in the manufacture of carbon disulfide. Carbon oxysulfide is also often present in refinery gases.

First aid

Gas: Move victim to fresh air. Call emergency medical care. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a oneway valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and quiet. Keep victim under observation for 24 to 48 hours. Effects of contact or inhalation may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Refrigerated liquid: Move victims to fresh air. Call emergency medical care. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and quiet. Keep victim under observation. Effects of contact or inhalation may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves

Shipping

UN2204 Carbonyl sulfide, Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 2.1-Flammable gas, Inhalation Hazard Zone C. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.

Purification Methods

Purify the gas by scrubbing it through three consecutive fritted washing flasks containing conc NaOH at 0o (to remove HCN), and then through conc H2SO4 (to remove CS2) followed by a mixture of NaN3 and NaOH solution; or passed through traps containing saturated aqueous lead acetate, then through a column of anhydrous CaSO4. Then it is freeze-pumped repeatedly and distilled through a trap packed with glass wool and cooled to -130o (using an n-pentane slurry). It liquefies at 0o/12.5mm. Use stainless steel containers. The gas is stored over conc H2SO4. [Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 654 1963.] TOXIC

Incompatibilities

Carbon oxysulfide can form explosive mixture with air. Incompatible with strong bases. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

Waste Disposal

Return refillable compressed gas cylinders to supplier. Dissolve in a combustible solvent, such as alcohol, benzene, etc. Burn in a furnace with afterburner and scrubber to remove SO2 .
