What are fatty acids. •The longer the Hydrocarbon chain the higher the melting point of the fatty acid. Fat in a corpse converts into adipocere, often called "grave wax".This process is more common where the amount of fatty tissue is high and the agents of decomposition are absent or only minutely present.

Saponification value. The saponification value is the amount of base required to saponify a fat sample. Soap makers formulate their recipes with a small deficit of lye to. Carnuba wax consists chiefly of myricyl cerotate (MW ) and small quantities of free cerotic acid (C26H52O2, Mw ) and myricyl alcohol (C30H62O, mp 90°C).

Of the two common extraction solvents, ethyl ether or petroleum ether, Lewkowitsch prefers the former. Concerning separation of phases, he advocates addition of small amounts of alcohol or caustic, and he. The hydrolysis of fats and oils in the presence of a base is used to make soap and is called saponification.

Today most soaps are prepared through the hydrolysis of triglycerides (often from tallow, coconut oil, or both) using water under high pressure and temperature [ lb/in 2 (∼50 atm or 5, kPa) and °C]. The Examination of Hydrocarbon Oils and of Saponifiable Fats and Waxes by David Holde () "D.
