Novozym® 435 as bio-catalyst in the synthesis of methyl laurate
Due to global temperature increase, the area of green chemistry is gaining more and more attention. The main goal is to replace petrochemicals with biobased chemicals from renewable feedstocks. In this work the reaction from vinyl laurate to methyl laurate and lauric acid has been investigated. The...
