04 · Handling and storage

Storing and handling Thiocarbonyl chloride

Incompatible materials

Reactivity with water: Evolves hydrogen chloride, carbon disulfide, & carbon dioxide. Reaction is slow unless water is hot.

Source: Hazardous Substances Data Bank (HSDB)

Reactivity

THIOPHOSGENE is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Liberates hydrogen sulfide upon reaction with acids.

Safety Data Sheet

Getting an SDS for Thiocarbonyl chloride

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Thiocarbonyl chloride issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
