WERKWIJZE TER BEREIDING VAN ESTERSMEERMIDDELEN.

摘要

Mixed ester products obtained by treatment of a triglyceride under transesterification conditions with a polyoxyalkylene glycol and a high molecular weight dicarboxylic acid, such as polymer acids, are useful metal working fluid. The modified triglycerides exhibit enhanced thermal stability and can be used either in neat form or in solution and are readily compatible with water to provide stable aqueous emulsions and dispersions having superior lubrication properties.
