Triphenylmethanol is a chemical compound from the group of alcohols and triphenylmethane derivatives .
Extraction and presentation
Triphenylmethanol can be obtained by reacting benzophenone with phenylmagnesium bromide .
It is also formed during the oxidation of triphenylmethane.
properties
Triphenylmethanol is a colorless solid that is insoluble in water; impure products are beige in color. When dissolved in concentrated sulfuric acid , an intensely yellow colored solution is formed by the formation of a triphenylmethyl carbocation.
use
Triphenylmethanol is used in numerous chemical syntheses and is the base of triphenylmethane dyes . For example, it can with acetyl chloride to trityl be implemented, which the introduction of the trityl - protecting group used.
