Ethyl chloride flammability limits

Highly poisonous, odorless, colorless, tasteless gas. Very flammable, burns in air with a bright blue flame. Ignition pt in air 700. mp-205.0. bp-191.5°. d - M (liq) 0.814. d (gas) 0.968 (air — 1.000). dg at 760 mm 1.250 g/liter. The top pressure is 1500 psi. Flammable limits in air 12 to 75 vol %. Crit press 35 atm, crit temp — 139. Heat capacity at 20° 6.95 cal/mole/ C. Heal value per m3 3033 keal. Heat of formation — 26.39 kcal/mol. Dec into carbon and carhon dioxide between 400 and 700°, at lower temp when in contact with catalytic surfaces. Above 800° the equilibrium reaction favors CO formation. Hopcalite, a mixture of the oxides of manganese and copper, catalyzes the decompn at room temp, as does Pd on silica gel. Sparingly sol in water 3.3 ml /100 ml HjO at O 2.3 ml/100 ml HjO at 2(T freely absorbed by a coned soln of cuprous chloride in HC1 or in NHjOH. Appreciably sol in some organic solvents, such as ethyl acetate. CHCI. acetic acid- The soly in methanol and ethanol is about 7 times as great as the soly in water. 

The flammable halocarbon gases and the vapors of the flammable liquids form explosive mixtures with air. The range of explosive limits is wide for vinyl chloride, methyl chloride, and ethyl chloride.
