As the quality of the delignified product, propionic acid would give better end product in higher yield as compared to the lower aliphatic acid that was observed.
Punctelia canaliculata produces atranorin, protolichesterinic acid, and an aliphatic acid possibly similar to caperatic acid [25].
The major phytochemical compounds among them were 4-(4-ethoxyphenyl) but-3-en-2-one, an aliphatic acid (peak area: 56.90%) (Figure 4(c)), trehalose, sucrose (peak area: 11.49%) (Figure 4(d)), hexadecanoic acid, methyl ester, a linoleic acid ester (peak area: 6.52%), and 9octadecenoic acid (Z)-, methyl ester, another linoleic acid ester (peak area: 6.76%).
8,535,649 B2; Chanel Parfums Beaute, Neuilly sur Seine, France, has patented cosmetic composition comprising, in a physiologically acceptable medium, at least one anhydrous gel having a viscosity of at least 180,000 cP*s at 25[degrees]C, which includes at least one oil and at least one copolymer of styrene and at least one olefin other than styrene; at least one ester obtained from a saturated or unsaturated and linear or branched aliphatic acid or hydroxy acid having from 8 to 30 carbon atoms, a linear or branched diacid having from 12 to 36 carbon atoms, and glycerol or a glycerol condensate; and optionally at most 10% by weight of wax(es).

Significant band shifting from 3423.19 (O- H stretching), 2925, 2847 (C-H symmetric and asymmetric stretching), 1731.34 (stretching vibrations of -COOH and -COOCH3), 1626.32, 1424.94 (C-OH of carboxyl), 1312.44 (C-O stretch in ester), 1262.67 (C-O of aliphatic acid groups), 1154.54 (C-O-C stretch in ether) and 1033.02cm-1 (stretching vibration of C-OH) on unmodified Citrus reticulata peels occurred after chemical modification.
IPA, seems to be comparable with that of the corresponding bifunctional aliphatic acid (SBA); the lower rate observed for the reaction with TPA (cf.
For the carboxylic component, different aliphatic acids were used i.e.
Consequently, we found that the sample was rich in hydrocarbons (3.06%), aliphatic acids and their esters (10.49%), cinnamic acids and their esters (0.57%), flavonoids (23.83%), alcohols and terpenes (3.19%), aromatic acids (0.44%) and ketones (1.22%).
These include aliphatic acids such as acetic, citric, isocitric, fumaric, tartaric, oxalic, formic, lactic, malic, malonic, butyric, succinic, trans-aconitic, propionic, adipic and glycolic acids, and cyclic and aromatic acids such as benzoic, phenylacetic, shikimic, phthalic, ferulic, syringic, p-coumaric, vanillic, p-hydroxybenzoic, m-hydroxybenzoic, benzoic, caffeic, protocatechuic, gallic, gentisic, sinapic, rosmarinic, and transcinnamic acids [3, 20-33].
Ester-based plasticizers include benzoates, isophthalates, adipates, phthalates, citrates, trimellitates and various glycol esters of aliphatic acids. Phthalate esters include dimethyl, dibutyl, diisobutyl, dicyclohexyl, as well as mixed esters of cyclohexyl, dibutyl, and cyclohexyl/isooctyl alcohols.
