condensation products of the phenols with phthalic acid, and
well represented by phenol phthale["i]n. Their alkaline
solutions are fluorescent.

substance made from phthalic acid and phenol. Its solution
in alkalies is brilliant red, but is decolorized by acids,
and as this reaction is exceedingly delicate it is used as
an indicator. Phenolate

Pertaining to, or designating, a strong organic acid (called
picric acid), intensely bitter.

nitric acid, as a brilliant yellow crystalline
substance, C6H2(NO2)3.OH. It is used in dyeing silk
and wool, and also in the manufacture of explosives, as
it is very unstable when heated. Called also
trinitrophenol, and formerly carbazotic acid. Trinitrophenol
