Chloroform Chemical Properties,Usage,Production

Chemical Properties
Colorless liquid
Usage
Suitable for HPLC, spectrophotometry, environmental testing
Usage
Meets ACS specifications.
Usage
Facilitates recovery of the aqueous phase of PCRs which have been overlaid with mineral oil.
General Description
A clear colorless liquid with a characteristic odor. Denser (12.3 lb / gal) than water and slightly soluble in water. Hence sinks in water. Nonflammable under most conditions, but burns under extreme conditions. May cause illness by inhalation, skin absorption or ingestion. Used as a solvent, to make other chemicals, as a fumigant.
Air & Water Reactions
Slightly soluble in water. Dissolves in water to form a corrosive solution of hypochlorous acid which decomposes on standing to chlorine, oxygen, and chloric acid.
Reactivity Profile
A mixture of acetone and Chloroform in a residue bottle exploded. Since addition of acetone to Chloroform in the presence of base will result in a highly exothermic reaction, Chloroform is thought that a base was in the bottle. [MCA Case History 1661(1970)]. Powdered aluminum and carbon tetrachloride(also methyl chloride and Chloroform or mixtures of these chemicals) exploded when heated(to 153°C.) and by impact, [Chem. Eng. News 32:258(1954); UL Bull. Research 34(1945), ASESB Pot. Incid. 39(1968)]. An inadequately cooled addition of sodium to a Chloroform-methanol mixture (sodium methoxide) caused a violent explosion, [MCA Case History No. 693]. Chloroform is incompatible with dinitrogen tetraoxide, fluorine, sodium metal and alcohols, nitromethane, and triisopropylphosphine.
Health Hazard
Chloroform is classified as moderately toxic. Probable oral lethal dose for humans is 0.5 to 5 g/kg (between 1 ounce and 1 pint) for a 150 lb. person. The mean lethal dose is probably near 1 fluid ounce (44 g). It is a human suspected carcinogen. Also, it is a central nervous system depressant and a gastrointestinal irritant. It has caused rapid death attributable to cardiac arrest and delayed death from liver and kidney damage.
Fire Hazard
Container may explode in the heat of fire. When heated Chloroform liberates phosgene, hydrogen chloride, chlorine and toxic and corrosive oxides of carbon and chlorine. Chloroform explodes when in contact with aluminum powder or magnesium powder or with alkali metals (e.g., lithium, sodium, and potassium) and dinitrogen tetroxide. Chloroform reacts vigorously with acetone in the presence of potassium hydroxide or calcium hydroxide. Chloroform is oxidized by strong oxidizers such as chromic acid forming phosgene and chlorine. Chloroform reacts vigorously with triisopropylphosphine. Chloroform develops acidity from prolonged exposure to air and light.
