Hazard Statements：

Disposal Methods：

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Each notification may be associated with multiple companies.

Preventive Measures：

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Ethanesulfonyl chloride Use and Manufacturing

Methods of Manufacturing

Derived from the reaction of ethyl thiocyanate and chlorine. Suspend 200 g of ethyl thiocyanate in 200 ml of water, and pass in chlorine gas under vigorous stirring at 0-5° C. until the reaction liquid appears persistently yellow. Then the chlorine is driven out by compressed air, the oil layer is separated, extracted with ether, and washed with sodium disulfide and sodium carbonate successively. After drying with calcium chloride, fractional distillation under reduced pressure, 71-72 ℃ (2.67kPa) distillate is collected, the product is about 230g. The yield is about 79%.

Uses

Used as medicine and pesticide intermediate

Production

Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#7154]
