The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
A tablet is usually a compressed preparation that contains: 5-10% of the drug (active substance); 80% of fillers, disintegrants, lubricants, glidants, and binders; and; 10% of compounds which ensure easy disintegration, disaggregation, and dissolution of the tablet in the stomach or the intestine.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
The output of these processes is a mixture of chloromethane, dichloromethane, chloroform, and carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation .
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.

A common formulation included "a variable amount of morphine, 10 mg of cocaine, 2.5 mL of 98% ethyl alcohol, 5 mL of syrup BP and a variable amount of chloroform water”. [1] Brompton's cocktail was given most in the mid-twentieth century. [2] It is now considered obsolete. [3] In popular culture it also came to be associated with medical ...
