ChloroformEdit

From PyroGuideEdit

Chloroform (also known as trichloromethane and methyl trichloride) is often used as a non-polar solvent. It is also used an anesthetic, however it has a higher toxicity as well as being an environmental hazard. It is more commonly found in refrigerants in today's usage

The chemical formula for Chloroform is CHCl3 and has a molar mass of 119.38g/mol. It has a melting point of -63.5°C, a boiling point of 61.2°C, and a density of 1.48g/cm^3, liquid. It's solubility in water is 0.8g/100mL at 20°C making it insoluble in water. It's flash-point is specified as non-flammable. It is a common solvent since it's usually nonreactive and miscible with most organic liquids where it may be volatile. == Safety==

Chloroform Hazards: Xn, Xi. It is also a Carcinogen NFPA 704 : Blue - 2, Red - 0, Yellow - 0, White - n/a R-Phases : R22, R38, R40, R48/20/22 S-Phases : (S2), S36/37

ProductionEdit

Editor's note: Please note this is only an overview

Between 400 and 500°C a mixture of chlorine and chloromethane and/or methane is heated. The reaction follows:

CH4 + Cl2 â†’ CH3Cl + HCl
CH3Cl + Cl2 â†’ CH2Cl2 + HCl
CH2Cl + Cl2 â†’ CHCl3 + HCl

Continuing the reaction we would also create

CHCl3 + Cl2 â†’ CCl4 + HCl

The reaction will contain all four types of chloromethanes and can be separated by distillation.

Inadvertent SynthesisEdit

Sodium Hypochlorite solution is mixed with either acetoneMEKethanol , or isopropyl alcohol  in addition to other substances. This is referred to as a haloform reaction.
