WebAliphatic hydrocarbons are organic compounds that mainly consist of carbon and hydrogen atoms. They can be straight-chained or branched, but they do not have any rings of alternating single and double bonds. Aliphatic hydrocarbons may be saturated (joined mainly by single bonds) or unsaturated (joined by double bonds or triple bonds). Webto the hydrophobic aliphatic alcohol chain (C ³ 6). The alkoxylate chain comprises mixed polyethylene glycol (PEG) and polypropylene glycol (PPG) repeats, which may be block, alternating, or randomly ordered chains (Lindner, 2010; CIR, 2016). The alkyl chain can be linear, branched, saturated or unsaturated in the AA group.

WebThese were initially known as Aliphatic compounds because the compounds of this class were derived from either animal or vegetable fats.
