Phloroglucinol

Chemical properties

Formaldehyde and resorcinol react under alkaline conditions to form orange-red compounds, which are colorimetric at a maximum absorption wavelength of 460nm to detect low traces of formaldehyde in textile and clothing.

Since resorcinol can undergo enol and ketone form tautomerism, it can react with ammonia as follows:

Ketone reaction of resorcinol

Under the action of ammonia, m-phenyltriamine is obtained by reaction in ketone, and the amine is hydrolyzed in the aqueous solution of acid to obtain resorcinol. Resorcinol can also be reacted in the form of enols:
