Abstract : A program was worked out to produce glycerol pectate on a larger laboratory scale. The first steps in the synthesis, the preparation of glycidol and the esterification of pectic acid, were designed on a relatively large scale to produce more adequate supplies for future studies. Subsequent steps such as thermal degradation, precipitation and lyophilization still have to be carried out on a comparatively smaller scale due to limitations in equipment. The major part of this report period was devoted to the construction and assembly of special apparatus required for production on the planned scale. This special equipment described herein, includes a stainless steel decomposer for glycerol carbonate, an esterification unit, an apparatus for thermal degradation and a mechanical bottle freezing unit. Promising results were obtained in clarification of glycerol pectate solutions by means of centrifugation. (Author)
