Modified Products of Saturated Fatty Acids

Halogens such as Cl, Br, and I can be introduced into the a-position of saturated fatty acids. For instance, the halogenation of palmitic acid with Br can be expressed as follows  

Fatty acid chloride has been used as collector in the flotation of hematite and apatite [6-8]. The main preparation method of fatty acid chloride is as follows  

When some unsaturated fatty acids exist in the reaction system, addition reaction occurs as follows  

Photometric quantity jx = 1800-5800 A Reaction temperature 60-70 °C Chlorine dose 0.2-0.23 kg/t min 

Dehydration Dry air is injected when the materials are heated to 80-90 °C Chlorination CI2 is injected when the materials are cooled to 60 °C. And the chlorination time is 50-60 h
