설명

일반 설명

Carbon disulfide (CS₂) is a colorless liquid. It is present in atmosphere and natural waters in the form of sulfur gas. It is responsible for the production of sulfur dioxide (SO₂) in the atmosphere (stratosphere and/or troposphere).[1] Its lifetime in the atmosphere has been proposed to be around 12 days.[2] It is a non-polar solvent.[3]

Carbon disulfide is a highly volatile, flammable liquid with low ignition temperature. It can be synthesized by reacting hydrocarbon gas with sulfur. It is an important raw material for preparing viscose rayon and cellophane film.[4]

애플리케이션

Carbon disulfide has been used for the desorption of air samples during analysis of trihalomethanes (THMs) in those samples.[5]
It may be used in the preparation of dibenzyl trithiocarbonate, a RAFT (Reversible Addition-Fragmentation Transfer) chain-transfer agent (CTA).[6] It may be employed as a solvent in the preparation of benzyl chlorodithioformate.[7]

Carbon disulfide may be used in the xanthogenation of cellulose[8] and in the synthesis of poly(ethylene trithiocarbonate)[9] and dithiocarbamates.[10] C₂S may undergo hydrolysis catalyzed by nanosized titania and zirconia to form CO₂ and H₂S.[11] It can also generate 1,3-dithiolium carbenes via cycloaddition with acetylenes.[12]
