Description
TECHNICAL DESCRIPTION
The present invention concerns a synthesis process of a biosolvent composition including an ester acid stemming from the biomass and an organic biosolvent. The process is based on an esterification reaction between an acid stemming from the biomass and an alcohol, in the presence of an acid catalyst and the selective of the ester formed with regard to the departure acid organic biosolvent. The present invention also concerns the biosolvent so obtained and the use of this biosolvent.
BENEFITS
Operatoring conditions were found to ameliorate the rendement in ethyl-lactate for more than 30% during esterification reaction between lactic acid and ethanol without using usual equilibrium deplacement methods (continuated elimination of water and/or alcohol excess).
INDUSTRIAL APPLICATIONS
Vegetal oils: printing, painting and surfaces, surface cleaning, phytosanitary, adhesives, customer products… Others (complex regulations): pharmacy and cosmetics, rubbers and plastics, oils extraction, wet cleaning.
