Some Cutting Oil Formulations Based on Local Prepared Emulsifiers Part I: Preparation of Some Emulsifiers Based on Local Raw Materials to Stabilize Cutting Oil Emulsions

The first main target of this work is to synthesis some emulsifiers from local raw materials used for cutting oil formulations. Seventeen emulsifiers (15 nonionic and 2 anionic) were prepared from locally available materials such as linear alkyl benzene sulfonic acid (LABSA), glycerol, polyethylene glycol, and maleic anhydride. Their chemical structures were confirmed using FTIR. The surface tension for the emulsifiers was measured at 25°C, and the surface and thermodynamic properties were calculated based on the surface tension parameters. The formulations of cutting oil fluids were prepared using these emulsifiers. The second target is to investigate the stability of soluble oil blends and emulsion stability of soluble oil in water. The results are discussed in the light of surface‐active properties and chemical structure of emulsifiers.
