Abstract: The present disclosure relates to processes for production of alkene products from their alkene precursors, such as 3~hydroxyacid and alcohols, via either (1) high temperature reactive distillation with steam contact at optimal pH, (2) solvent extraction and Mulzer dehydration, (3) solid phase adsorption, desorption into an organic solvent and catalytic reaction and (4) high temperature reactive distillation with steam contact at optimal pH followed by catalytic conversion.
