Web—Glycerin was discovered, in 1779, by Scheele in the saponification products of olive oil by means of litharge, and later recognized by him as a common constituent of other oils and fats, and therefore named the "sweet principle of fats." Chevreul gave it the name glycerin, and cleared up the nature of its combination in the fats. Webmolecule of litharge reacted with one molecule of glycerine. The struct-ural formula for the load glyceride is written as above only for the sake of symmetry. The above reaction is … foam runner outfit ideas

http://www.hydroinstruments.com/files/Nitrogen%20Purging.pdf WebIn the late 1700s K. W. Scheele, the Swedish chemist accidentally discovered glycerin. One day he was heating a mixture of olive oil and litharge (lead monoxide) and in the course of the experiment. The glycerol thereby was manufactured by following the course. He described alcohol as the “sweet principle of fat.” Webdecided to use ordinary glycerine, rather than to attempt the somewhat laborious task of obtaining it in an anhydrous condition. In the following reaction litharge was combined with four times the theoretical amount of glycerine. 60 c.c. of glycerine were heated in a beaker to a temperature of 90P- 100°C., using a water bath to maintain foam runners and shorts
