HYDROLYSIS OF METHYL ESTERS FOR PRODUCTION OF FATTY ACIDS

THE PRESENT INVENTION RELATES TO AN IMPROVED PROCESS FOR PREPARING FATTY ACIDS FROM ALKYL, PREFERABLY METHYL ESTERS VIA ACID HYDROLYSIS BY USING RATIOS OF WATER/ESTER/ACID CATALYST TO FORM SINGLE PHASE REACTION MIXTURES WHEREIN THE INITIAL STOICHIOMETRIC RATIO OF WATER TO ESTER IS AT LEAST ABOUT 1:1...

Zusammenfassung:	THE PRESENT INVENTION RELATES TO AN IMPROVED PROCESS FOR PREPARING FATTY ACIDS FROM ALKYL, PREFERABLY METHYL ESTERS VIA ACID HYDROLYSIS BY USING RATIOS OF WATER/ESTER/ACID CATALYST TO FORM SINGLE PHASE REACTION MIXTURES WHEREIN THE INITIAL STOICHIOMETRIC RATIO OF WATER TO ESTER IS AT LEAST ABOUT 1:1. THESE RATIOS ARE REPRESENTED BY THE TERNARY PHASE DIAGRAM OF FIG. 1 FOR A PREFERRED C6-C14 ALKYLBENZENE SULFONIC ACID CATALYST HAVING MID-POINT ATTACHMENT OF THE ALKYL CHAIN TO THE BENZENE RING.
