Webnatural fatty alcohols, the former manufactured from petro-chemicals. Naturally derived fatty alcohols are produced from natural fats and oils by hydrogenation of their fatty acids or fatty acid methyl esters (FAME). By the year 2000, natural alcohols are expected to account for 65% of the world’s steadily growing fatty alcohol demand (1).
WebA hydroxyl (alcohol group) is an –OH group covalently bonded to a carbon atom. The oxygen atom is much more electronegative than either the hydrogen or the carbon, which will cause the electrons in the covalent bonds to spend more time around the oxygen than around the C or H. origin of word lawhttp://chemistry.elmhurst.edu/vchembook/213organicfcgp.html origin of word kitschFor organic compounds, the length of the C-O bond does not vary widely from 120 picometers.
