WebSep 15, 2024 · NaOH + CCl3CH (OH)2 → CHCl3 + HCOONa + H2O Physical Properties of Chloroform Chloroform is a colorless liquid. Its boiling point is 61°C. Its smell is sweet and distinct. Breathing in its vapors leads to unconsciousness. It is almost immiscible in water but miscible in ether and alcohol. WebWhen phenol is processed with chloroform inside the ubiquity of NaOH, a CHO group is added at ortho function of the benzene ring. This reaction is understood as the Reimer-Tiemann reaction. The intermediate form which is substituted benzyl chloride is hydrolysed within the presence of alkali to supply salicylaldehyde as a product.

In chemistry, the haloform reaction is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base. The reaction can be used to transform acetyl groups into carboxyl groups (R−C(=O)OH) or to produce chloroform (CH… 76直播 足球Dichlorocarbene is most commonly generated by reaction of chloroform and a base such as potassium tert-butoxide or aqueous sodium hydroxide. A phase transfer catalyst, for instance benzyltriethylammonium bromide, facilitates the migration of the hydroxide in the organic phase.
