Lipase-catalyzed acidolysis of butterfat with oleic acid: characterization of process and product
Enzyme and Microbial Technology, 1998 The modification of anhydrous butterfat via interesterification reactions with oleic acid catalyzed by a lipase from Mucor circinelloides immobilized by adsorption onto hydrophobic hollow fibers is described. A reasonable degree of incorporation of free (externally added) oleic acid into the triacylglycerols of butterfat has been achieved while short ...

Polyurethane Foam Chemical Recycling: Fast Acidolysis with Maleic Acid and Full Recovery of Polyol [PDF]
Chemical recycling of polyurethane (PU) waste is essential to displace the need for virgin polyol production and enable sustainable PU production. Currently, less than 20% of PU waste is downcycled through rebinding to lower value products than the ...
