Alcooli grași superiori C8-C20
Explanation:
Termenul de “gras” provine din faptul că își au originea în grăsimi, în general au mai mulți atomi de carbon (sau aceștia constituie interes pentru industrie) așa cum apare aici:

http://en.wikipedia.org/wiki/Fatty_alcohol

dar pot să apară și cu un număr mai mic de atomi de carbon, de exemplu:

Saturated fatty alcohols up to dodecanol are clear, colorless liquids. The next higher homologues are soft
materials; tetradecanol and higher alcohols have a waxy consistency.

http://www.zenitech.com/documents/new pdfs/articles/All abou...

aici apare și definiția care nu precizează lungimea catenei:

Any of various alcohols derived from plant or animal oils and fats and used in plastics and pharmaceuticals.

http://www.thefreedictionary.com/fatty alcohol

higher se referă la cei superiori, adică cu un număr de atomi de C mai mare
