Many organic liquids, including oils (essential, animal, vegetable or mineral), alcohols, fatty acids, chlorinated hydrocarbons and aliphatic esters, are without action. The absence of any catalytic action of tin on oxidative changes is helpful in this respect. When, however, mineral acidity can arise, as with the chlorinated hydrocarbons containing water, there may be some corrosion, especially at elevated temperature. 

Chlorinated Fatty Acids. Chlorination of carboxylic acids is much more difficult because the contribution or the carbonyl group toward proton removal is offset by the electron donation effect from the hydroxyl group. This hindrance is obviated by reaction with the acid chloride or anhydride. Chlorination is normally accomplished hy use of n catalyst, such as phosphorus trichloride. Monochloroacelic acid is an important industrial chemical. Dichloro- and trichloroacetic acids can he produced by further chlorination, although the latter can be produced convenienlly by nitric acid oxidation of chloral. Higher chlorinalcd tally acids can be produced by treatment or the hydroxy carboxylic acid or ester with HCI ur PCL ... 

The reaction of chlorine in flour with unsaturated fatty acids, which are also alkenes, yields a number of fatty acid chlorinated derivatives (dichloroacids and chlorohydroxyacids). Chlorohy-droxyacids are formed preferentially with chlorine dioxide. For example, oleic acid produces 9,10-dichlorostearic, 9-chloro-lO-hydroxystearic and 10-chloro-9-hydroxystearic acids. From linoleic acid the corresponding disubstituted derivatives of oleic add or tetrasubstituted derivatives of stearic acid are formed. Their content in flour, depending on the amount of chlorine used for bleaching, is given in Table 11.14. Chlorinated fatty adds are also formed in the fat of chicken carcasses that are cooled in chlorinated water after slaughter. 

Additives for lubricating oils providing a combination of viscosity index improvement (VII) and dispersancy have also been reported. These additives are prepared from ethyleneamines by reaction with various Vll-type polymers that have been chlorinated or modified in some other way to provide an ethyleneamine reaction site. Antimst additives for lubricating oils have been prepared by reaction of polyamines with fatty acids followed by reaction with polyalkylenesuccinic anhydrides (178,179).

The chloride ion is the most frequent cause of contact corrosion, since chlorine is present in the many chlorinated plastics, and is also frequently retained in residual amounts from reactive intermediates used in manufacture. Thus epoxides usually contain chloride derived from the epichlor-hydin used as the precursor of the epoxide. In addition to the contaminants referred to in Table 18.18, various metal and ammonium cations, inorganic anions and long-chain fatty acids (present as stabilisers, release agents or derived from plasticisers) may corrode metals on contact.

On-line SFE-pSFC-FTD, using formic or acetic acid modified CO2 as an extraction solvent, was used to analyse a dialkyltin mercaptide stabiliser in rigid PVC (Geon 87444) [114]. Hunt et al. [115] reported off-line SFE-pSFC-UV analysis of PVC/(DIOP, chlorinated PE wax, Topanol CA), using methanol as a modifier. Individual additives are unevenly extracted at lower pressures and temperatures, where extraction is incomplete. Topanol CA, the most polar of the three PVC additives studied, could not be fully extracted in the time-scale required (15-20min), even at the highest CO2 temperature and pressure obtainable. However, methanol-modified CO2 enhances extraction of Topanol CA. PVC film additives (DEHP, fatty acids, saturated and aromatic hydrocarbons) were also separated by off-line SFE-preparative SFC, and analysed by PDA and IR [116]. 

If the nickel is introduced into the fatty acid in the solid form it is important that it should be absolutely free from sulphur, selenium, tellurium, arsenic, chlorine, iodine, bromine. Further, it is important that the nickel should have been prepared by the reduction of the oxide at a temperature not exceeding 300° C, and should not have been long exposed to the air prior to its use.

Elforts have been made to characterize the nature and content of individual components that are present in the low-molecular-mass fraction of the total mill effluents, which include the spent chlorination and alkali extraction stage liquors [2,4]. Approximately 456 types of compounds have been detected in the conventional bleach effluents, of which 330 are chlorinated organic compounds [22]. The compounds may be lumped into three main groups, namely, acidic, phenolic, and neutral (Table 2). Acidic compounds are further divided into the five categories of acids fatty, resin, hydroxy, dibasic, and aromatic acids. The most important fatty acids are formic and acetic acids. The dominant resin acids are abietic and dehydroabietic acids. Among the hydroxy acids identified, glyceric acid predominates. Dibasic acids such as oxalic, malonic, succinic, and mafic acids are derived from the lignin and carbohydrate fraction...

Amino fatty acids can he treated wilh a mixture of nitric oxide and chlorine to produce the corresponding chloroacid. Mono- and dichlorosuccinic acids are examples of chlorinated dicarboxylic acids. 

The interaction of diaryl tellurides and the esters of halogenated fatty acids, e.g. methyl bromacetate, gives diarvl-telluretin halide alkyl esters, e.g. (C6H5)2Te(Br).CH2.COOCH3. The halogen present may be chlorine, bromine or iodine, moist silver oxide replacing the bromine by the hydroxyl group. 

A commercially available column containing silver ions has recently been developed by Chrompack (ChromSpher Lipids HPLC column). A solvent system (43) composed of dichloro-methane, dichloroethane, and small amounts (0.01-0.025%) of acetonitrile (ACN) is used with both the Nucleosil and Chrompack HPLC columns. Because chlorinated solvents are opaque at the wavelengths (200-210 nm) used for FAME analyses, the use of UV detectors is precluded unless the phenacyl derivatives of the fatty acids are first prepared.
