Carbon disulphide autoignition temperature

Salts of O-alkyldithiocarbonatcs ( xanthates ) are hazardous as dusts, forming explosive suspensions in air. The lower-alkyl salts are claimed to be explosive in the solid state when dry [1]. Explosions reported when drying hydrated xanthate salts are probably the consequence of release of carbon disulphide to form an inflammable atmosphere of very low autoignition temperature in the oven [2], Xanthate esters are thermally unstable by a variety of eliminations and rearrangements, all distinctly exothermic and many evolving extremely flammable gases and vapours. Free xanthic acids, which may be isolated on acidification, decompose autocatalytically and perhaps explosively [3],... 

Carbon disulphide has the very low autoignition temperature of 100°C. The vapour may therefore ignite on contact with steam pipes or with boiling water baths. 

CARBON DISULFIDE or CARBON DISULPHIDE (75-15-0) CSj Extremely flammable extremely low ignition temperature makes it very dangerous. Forms explosive mixture with air [explosion limits in air (vol %) 1.3 to 50 flash point -22°F/-30°C autoignition temp 194°F/90°C Fire Rating 3]. Highly reactive substance. Shock, friction, or concussion can cause explosive decomposition. Contact with...
