CHAPTER VI
CHAPTER VI
The bulletin on "By-Products of the Lumber Industry" by H.K. Benson (published by Department of Commerce, Washington, 10 cents) contains a description of paper-making and wood distillation. There is a good article on cellulose products by H.S. Mork in Journal of the Franklin Institute, September, 1917, and in Paper, September 26, 1917. The Government Forest Products Laboratory at Madison, Wisconsin, publishes technical papers on distillation of wood, etc. The Forest Service of the U.S. Department of Agriculture is the chief source of information on forestry. The standard authority is Cross and Bevans' "Cellulose." For the acetates see the eighth volume of Worden's "Technology of the Cellulose Esters."
О книге
Slosson reviews the transformation of alchemistry from an obscure and imprecise practice to the science of chemistry. Along the way, he explains how the modern industrial world now relies on fertilizers, explosives, textile materials, polymers and metals.
By exploring the properties of a once undervalued element, the high strength of vanadium steel made the Ford car possible. Another element, cerium, appears in butane lighters and was once seen as a threat to the match industry in France.
In his chapter on oils, Slosson reviews the development of hydrogenated oils, especially during WWII, in the search for a way to reuse otherwise discarded components of corn and cottonseed. Through the revolutionary reaction of hydrogenation, waste materials became a stable product that wouldn't spoil when packaged or carried without refrigeration. Once thought of as a miracle, shoppers were once willing to pay more for fully hydrogenated oils than their natural, unsaturated forms. Only in recent years has evidence of health risks checked their popularity and given them the image of cheap, unhealthy fillers. (Summary by LivelyHive)
