What category is chloroform?
Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, strong-smelling, dense liquid that is produced on a large scale as a precursor to PTFE.
What is chloroform used for today?
Chloroform is used as a solvent, a substance that helps other substances dissolve. Also, it is used in the building, paper and board industries, and in pesticide and film production. It is used as a solvent for lacquers, floor polishes, resins, adhesives, alkaloids, fats, oils and rubber.
What is chloroform used for cleaning?
Chloroform is a clear liquid with an ether-like odor and a slightly sweet taste. Chloroform is a member of a group of chemicals called “trihalomethanes.” It is used to make coolants, as a fumigant for grain, and as a dry cleaning spot remover.

How do you identify chloroform?
Chloroform appears as a clear colorless liquid with a characteristic odor. Denser (12.3 lb / gal) than water and slightly soluble in water. Hence sinks in water.
Why is chloroform unstable?
It is slightly soluble in water and is miscible with oils, ethanol, ether, and other organic solvents. Chloroform has a pleasant, nonirritating odor. It is unstable when exposed to air, light, and/or heat, which cause it to break down to phosgene, hydrochloric acid, and chlorine.
Why is chloroform a good solvent?
So, basically, by virtue of the fact that chloroform is not miscible with water, it is an organic solvent. However, because chloroform does have some polarity, it can dissolve compounds ranging from moderately polar to moderately nonpolar.
What works faster chloroform?
Induction with fluothane was faster than with chloroform and ether. Fluothane seems slightly more potent than chloroform and has an equal margin of safety.
What are the LD50 values for chloroform?
Toxicological Data on Ingredients: Chloroform: ORAL (LD50): Acute: 695 mg/kg [Rat]. 36 mg/kg [Mouse]. 820 mg/kg [Guinea pig].
What kind of odor does chloroform have?
Chloroform is a colorless liquid that is not very soluble in water and is very volatile. (1,6) Chloroform has a pleasant, nonirritating odor; the odor threshold is 85 ppm. , and it has a molecular weight of 119.38 g/mol.
Which is the best description of a chemical grade?
A chemical grade of sufficient purity to meet or exceed requirements of the U.S. Pharmacopeia (USP); acceptable for food, drug, or medicinal use; may be used for most laboratory purposes. 4. N.F. A grade of sufficient purity to meet or exceed requirements of the National Formulary (NF).
What was chloroform used for in the past?
(1) Chloroform was used in the past as an extraction solvent for fats, oils, greases, and other products; as a dry cleaning spot remover; in fire extinguishers; as a fumigant; and as an anesthetic. However, chloroform is no longer used in these products.
Which is the highest grade of chemical purity?
High purity generally equal to A.C.S. grade and suitable for use in many laboratory and analytical applications. 3. U.S.P. A chemical grade of sufficient purity to meet or exceed requirements of the U.S. Pharmacopeia (USP); acceptable for food, drug, or medicinal use; may be used for most laboratory purposes.
