phloroglucinol

The aldehyde gives very characteristic colour reactions with phloroglucinol and resorcinol in presence of hydrochloric acid, which so closely resemble those of the lignocelluloses that there is little doubt that these particular reactions must be referred to the presence of the hydroxyfurfural as a normal constituent.

Of the _trihydroxybenzenes_ pyrogallol and phloroglucinol only were included in these investigations.

The presence of diresorcinol is without influence on the result, provided a sufficient excess of actual phloroglucinol is employed.

Of importance also is the identification of the hydroxyfurfurals as constituents of the lignocelluloses generally, and the proof that the characteristic colour-reactions with phenols (phloroglucinol) may be ascribed to the presence of these compounds (p. 116).

Sulphonation of phloroglucinol succeeds at higher temperatures only, the sulphonic acid being a solid which is scarcely soluble in water, the latter then assuming a wine-red colour.

Councler substitutes phloroglucinol for pyrogallol, with the advantage of doing away with the digestion at high temperature.
