During pyrolysis, mostly straight-chain
alkanes are generated whereas both straight-chain
and branched alkenes are obtained.
The hydrotreating process of vegetable oil involves the transformation of vegetable oil triglycerides into straight-chain
In the light of the stringent environmental laws, isomerization is a good process as it enhances the octane number of hydrocarbons especially lighter hydrocarbon in the range of C5-C6 by converting their straight-chain
structure into branched chain structure without producing aromatics in the products .
Asphaltenes have been shown to exhibit polymeric behavior, be soluble in aromatics and longer straight-chain
hydrocarbons, and insoluble in alcohols and water, increase viscosity and stiffness, and harden softer petroleum fractions.
Butane ([C.sub.4][H.sub.10]): A straight-chain
or branch-chain hydrocarbon extracted from natural gas or refinery gas streams, which is gaseous at standard temperature and pressure.
Comment: Azelaic acid is a 9-carbon straight-chain
dicarboxylic acid that occurs naturally in some foods.
higher alcohols are considered to have the most significant sensorial impact (1-propanol, 2-methyl-1-propanol (isobutyl alcohol), 2-methyl-1-butanol and 3-methyl-1-butanol (isoamyl alcohol).
It is comprised of a structuring agent consisting of a low molecular mass N-acyl glutamic acid diamide having a straight-chain
alkyl group comprising dibutyl lauroyl glutamide, a low molecular mass N-acyl glutamic acid diamide having a branched-chain alkyl group comprising dibutyl ethylhexanoyl glutamide, and at least one polyorganosiloxane polymer comprising a nylon-611/dimethicone copolymer.
About 50 individual features for isopropyl cyanide (and 120 for normal-propyl cyanide, its straight-chain
sister molecule) were identified in the ALMA spectrum of the Sagittarius B2 region.
aldehydes may result from B-oxidation of unsaturated FA or from amino acids by strecker degradation.
They determined the primary source of the odor to be benign substances known as "carboxylic acids" and "straight-chain
aldehydes." Fortunately, the odors didn't repel the bees and dissipated after a few months, according to the beekeepers.
