Dichlorostearic acid

Stearolic acid has been prepared by the dehydrohalogenation of brominated olive or almond oil,3 dibromostearic acid,4 or dichlorostearic acid.6 The procedure described is a modification of one used by Kino.4...

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.
