MT 80 - Residue on evaporation

Content Handbook F


Outline of method

80.1 Low boiling products

Seventy five per cent of the sample is distilled. The residue in the flask is transferred to a weighed dish, and the evaporation completed on a water bath; the residue remaining on completion of the test is determined by weighing.

80.2 Cresols

The weight of residue is determined after evaporation of the sample, first on a boiling water bath and then in an oven at 105°C.
