Abstract

A METHOD FOR PRODUCTION OF ALKYL ESTERS FROM A MIXTURE OF GLYCERIDES AND FREE FATTY ACIDS, ORIGINATING PRIMARILY FROM GREASE TRAP WASTE, IS PROVIDED.@THE MIXTURE IS FIRST SOLVATED IN A LOW BOILING POINT ALCOHOL AND THEN THE PH OF THE SOLUTION IS ADJUSTED TO ABOUT 1 TO 2 BY ADDITION OF AN ACID TO EFFECT ACID-CATALYSED ALKYL ESTERIFICATION. THE ACIDIC SOLUTION IS THEN TREATED WITH A CONCENTRATED ALKOXIDE SOLUTION TO RAISE THE PH OF THE SOLUTION TO ABOUT PH12 TO EFFECT BASE-CATALYSED TRANSESTERIFICATION OF GLYCERIDES CONTAINED IN THE MIXTURE. THE RESULTING SOLUTION IS THEN TREATED WITH AN ACID TO DECREASE THE PH OF THE SOLUTION TO ABOUT 2 TO EFFECT ACID-CATALYSED ESTERIFICATION OF RESIDUAL SAPONIFIED BY-PRODUCTS.@THE ALCOHOL SOLVENT IS REMOVED BY DISTILLATION OR OTHER SUITABLE TECHNIQUE AND THE RESULTING ALKYL ESTERS ARE SEPARATED FROM ANY REMAINING RESIDUES AND NEUTRALISED OF RESIDUAL ACIDS.
