Chicago Section Meeting
Gemini Surfactants: Unique Emulsifiers for Metalworking Applications
November 15, 2012
Title: Gemini Surfactants: Unique Emulsifiers for Metalworking Application
Presenter: Dr. Tom Oleksiak, The Lubrizol Corporation
Gemini surfactants have utility for metalworking operations. These surfactants are prepared by connecting two alkenyl succinic anhydrides via a bridging group. The bridging group has two sites of reaction for the anhydride groups. The resulting structures, which are anionic in nature, are salted with amines to act as oil-in-water emulsifiers. Emulsification properties were found to be improved synergistically by blending with synthetic sodium sulfonate. Performance of this chemistry as an emulsifier can be optimized for a particular oil by varying the molecular weight of the alkenyl succinic anhydride and by changing the salting amine. This work was presented at STLE 2012. This presentation will review the previous work as well as update recent developments.
