Descripción

General description

Carbon disulfide is a sulfur containing gas. Its natural and anthropogenic sources of emissions in earth atmosphere has been investigated. Its lifetime in atmosphere has been proposed to be around 12 days. It is a non-polar solvent.

Application

Carbon disulfide may be used in the preparation of dibenzyl trithiocarbonate, a RAFT (reversible addition-fragmentation transfer) chain-transfer agent (CTA). It may be employed as solvent in the preparation of benzyl chlorodithioformate.
