Fatty derivative

In addition to copolymerisation, polyethylenes terrninated as ketones, alcohols, and carboxyHc acids with molecular weights as high as 700 daltons are now available. The products offer the same chemical functionaHty as common fatty alcohols and acids, but are higher melting and harder. Similar to the fatty alcohols and acids, derivatives such as ethoxylates, esters, and amides also are available as higher melting versions of the fatty derivatives.

Dry fractionation is defined as crystallization from a melt without dilution with solvent (O Brien, 1998 Anderson, 1996 Bailey, 1950). This process is the simplest and least expensive process for separating high and low-MP fatty derivatives (Illingworth, 2002 Kellens and Hendrix, 2000 O Brien, 1998 Anderson, 1996 Krishnamurthy and Kellens, 1996). It is also the most commonly practiced form of fat fractionation technologies currently in use (Illingworth, 2002 O Brien, 1998). 

The Biodiesel Stability (BIOSTAB) project, supported by the European Commission, was initiated in 2001 to establish clear criteria and analytical methods for the monitoring biodiesel fuel stability (Various, 2003 Prankl, 2002). The resulting unified method, EN 14112 (Anon., 2003c) established a means for measuring oxidative stability utilizing the Rancimat or oxidation stability instruments. This test method was essentially developed from standards employed in the fats and oils industry to measure isothermally the induction period for oxidation of fatty derivatives. At present, both biodiesel fuel standards ASTM D 6751 (Anon., 2007a) and EN 14214 (Anon., 2003b) include an oxidative stability specification based on measurement by method EN 14112. 

Many advances have been made in development of P-DSC and other thermal analysis techniques in the study of oxidation reactions in fatty derivatives such as biodiesel. Kinetic parameters and phase transitions associated with oxidative degradation may be rapidly and accurately determined. However, the applicability of P-DSC may be limited in analysis of fuel formu-... 

Other techniques to be investigated for analyzing effects of oxidation on fatty derivatives include monitoring PV, conjugated dienes, anisidine value, and carbonyls. Spectroscopic methods include electron spin resonance, infrared, fluorescence, chemiluminescence, and NMR (Shahidi and Wanasundara, 1998).

AMalassezia strain SA20 (KFCC 11252) was also used for the synthesis of AA from unsaturated fatty derivatives [122]. Sarcina lutea ICR2010 was observed to oxidize isobutyl oleate to AA (0.09 mg/ml) besides 10-oxostearic acid and 4-oxolauric acid [123]. 

The epoxidation of unsaturated fatty material has been studied by numerous investigators (4). Epoxidation of unsaturated oils or fatty derivatives such as methyl esters can be performed using either pre- or in itw-formed peracids in situ epoxidation can be accomplished by using hydrogen peroxide with formic or acetic acids (5). Formic acid is preferred to acetic acid because of its high reactivity. 

Secondary products were also formed during the reaction including the following (i) fatty derivatives by dehydration, catalyzed by aeid catalyst (PTSA), as shown by the increasing iodine value (ii) products resulting fi-om the transesterification with ethanol such as the ethyl ethoxyhydroxystearate and (iii) dimers.

SMEs and sulfonated fatty acids are commercially available as blends for use in household and personal cleaning products. As cleaning and personal-care formulations become more concentrated and milder, alpha-sulfo fatty derivatives will become even more attractive. Also since methyl esters are an abundant feedstock, their conversion to SMEs for use as bulk anionics is likely to grow. As quoted by Ed A. Knaggs, a former Stepan employee As already stated, alpha sulfo fatty derivatives have exceptional and unique properties which can be varied and tailored to meet an extremely wide variety of surfactant applications Hence, their acceptance is basically limited only by research,...

Another interesting characteristic of platelet PE is the presence of palmitaldehyde, stearaldehyde, and other plasmalogens (12). These alk-l-enyl type glycerophospholipids increased with age in the 3 population study (10) (Tables II and III). The functional significance of this type of fatty derivative is still unknown.
