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%).
Extraction of cellulose by catalytic reduction of lignin from bagasse with aliphatic acids
. Pakistan Journal of Biochemistry and Biology, 45: 225-228.
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.
Influence of aliphatic acids
on spore germination of wood decay fungi.
Small aliphatic acids
are well represented in both data sets, and it is likely that they target the acid-sensitive channel receptor found in the trigeminal system (ASIC) and in sensory neurons involved in taste (Waldman et al., 1997).
Therefore, various copolymer derivatives of PA6T are on the market, made of TPA and other aromatic acids or aliphatic acids
and melting at about 300[degrees]C (Ems-Chemie, BASF, Mitsui, DuPont, Solvay).
The exact composition is a secret, but Plasticine is composed of calcium salts (principally chalk), petroleum jelly, and long-chain aliphatic acids
. The original factory was destroyed by fire in 1963 and replaced by a modern building, and production continued until 1983.
Other examples are aliphatic acids
in the breath of people with liver cirrhosis,and di or trimethylamine in the breath of those with failing kidneys.
Synthetic polyesters made from aliphatic diols and aliphatic acids
are also biodegradable.
Aliphatic and aromatic acids were separated on a 5-[micro]m spherisorb octyl C-8 (250 by 4.6 min) (Biorad Aminex HPX87H) chromatography column, using a UV-visible detector set at 212 nm for aliphatic acids
and 254 nm for aromatic acids.
