Around 2800 B.C.E, the ancient Babylon excavations uncovered cylinders with inscriptions for making soap.1 In 1500 B.C.E, records from ancient Egypt described how animal and vegetable oils were combined with alkaline salts to make soap. Chemistry. Close enough. A comprehensive literature search on egg cholesterol content showed that there is a wide range of results, primarily because of the breed of laying hens and production practices [], but also could be due to the method of cholesterol quantification.The standard method for quantification of cholesterol is saponification (AOCS method Ca 6b-53) followed by GC. I have a data.table where I want to carry forward the last observation. Scum dissolved with phosphate? CSTR Analysis: Using your understanding of the saponification reaction, design a set of experiments to examine the continuous stirred tank reactor.
