Title:
BIO-BASED CROTONIC ACID PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2016/039618
Kind Code:
A1
Abstract:
The invention provides method for producing high selectivity trans-crotonic acid from bio-based resource wherein the steps comprise of treatment of poly(3-hydroxbutyrate) (PHB) biomass with mild alkali; and thermal degradation of the PHB biomass. Crotonic acid, a dehydrated monomer of PHB, can be obtained by thermal degradation under controlled temperature and retention time. Currently, crotonic acid is chemically synthesized via non-renewable resources. As an alternative, it can be produced biologically within cells in its hydrated polymer PHB form, and subsequently pyrolyzed to obtain crotonic acid. The invention also provides a method of producing crotonic acid by thermal degradation of wet or dry PHB biomass in the presence of magnesium compound. The present invention provides a method for treating PHB Biomass with low concentration of sodium hydroxide with molarity in between 0.05-0.1M.
