Production Process of Oxidized Paraffin Soaps

The flowchart of oxidized paraffin soaps is shown in Fig. 2.1. The main production conditions of oxidized paraffin soaps are as follows. 

The oxidizing reaction is motivated by the addition of KMnOa and NaaCOs at a high temperature. Then, air is injected into the reaction tank at 150 °C. The productivity of oxidized paraffin soaps can reach 95 % when the acid value of reactive liquid approaches a certain threshold. 

The reactive liquid of oxidized paraffin soaps is moved to soaping kettle. And oxidized paraffin soaps are separated by water dilution method when oxidized paraffin has been soaped at 90-95 °C in the presence of NaOH. The upper unsaponifiable matter is separated out. The main ingredients of unsaponifiable matter are aldehyde, ketimine, and unreacted paraffin. The productivity of unsaponifiable matter is about 25-30 %. 

The quality of oxidized paraffin soap varies with the production condition and raw material. The characteristics of two oxidized paraffin soaps can be seen from the following
