David C,
The chapter you need to concentrate on is Ch 8: "The recovery
and refining of glycerine". 62 pages in total covering a wide range of
topics in relation to Glycerine including: Analytical tests and
specifications, Purification of soap lyes and sweet waters, Evaporation of
Purified liquors to crude glycerine (includes removal and recovery of salt),
Treatment of crude glycerine to remove low molecular mass fatty acids,
DISTILLATION OF GLYCERINE (23 pages of good info and line drawings),
Bleaching and the treatment of distillates with ion-exchange resins to
upgrade quality, and Production of refined grades of glycerine without
distillation (ion exclusion, ion exchange, and reverse osmosis).
Forget Britannica, that is for people who only want a bit of general
knowledge and a general intro. A book like the Woolatt book if it dosnt
provide enough info points to and leads to more specific info and processes.
The trouble with man is not that he is stupid (which he certainly is) but
that half of have never learned to think, or that we read inferior books or
have inferior teachers. Half the teachers out there should still be at
school. The best teachers are an active mind and the University of Life.
While solving this problem on a large commercial scale is easy it certainly
is not so easy on a smaller scale.
