Description
C11C covers the extraction, isolation, and chemical transformation of fatty acids from natural sources (fats, oils, and waxes), as well as the manufacture of candles and chemically modified lipid products. This includes hydrogenation, oxidation, esterification, and other chemical processes that alter the properties of fatty substances for industrial or consumer applications. The classification encompasses both traditional candle production and modern derivatives used in pharmaceuticals, cosmetics, lubricants, and food additives, excluding crude oil refining and purely physical separation processes covered elsewhere in C11.
Scope Notes
Glossary: Fat fats Solid triester of glycerol and (mostly) saturated fatty acids Fatty acid fatty acids Any of a class of aliphatic monocarboxylic acids that form part of a lipid molecule and can be derived from fat by hydrolysis; nearly all fatty acids are built around a series of carbon atoms linked together in a chain of 4 to 28 carbon Esterification A chemical reaction resulting in the formation of at least one ester product. Hydrogenation Chemical process that adds hydrogen atoms to an unsaturated fat or fatty acid Isomerisation Process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms are rearranged e.g. A-B-C → B-A-C, usually requiring special conditions of temperature, pressure, or catalysts Lipid lipids Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells. Wax waxes Any of a group of substances composed of hydrocarbons, alcohols, fatty acids, and esters that are solid at ordinary temperatures. They are similar to fats, but are less greasy and more brittle. | Limiting references: Sulfonated fats or oils Epoxidised fats Natural vulcanised oils, e.g. factice Recovery of fatty acids from waste materials | Application references: Drying-oils; Methods of obtaining and chemically modifying
