PRODUCTION OF STABLE GLYCERIDES  OF CITRIC ACID:  GLYCEROL BLENDS

Unique, inexpensive, solid, amorphous glycerides (citric acid polyester biopolymers) were obtained by short term microwave treatments, i.e., 48 or 60 sec, from various citric acid:glycerol blends.  These biopolymers were produced without use of additional solvents, catalysts, plasticizers or complicated chemical synthesis procedures.  Fourier transform infrared (FT-IR) spectroscopy of these glycerides showed that citric acid formed stable polyesters and strong hydrogen bonds with glycerol.  Glycerides examined with differential scanning calorimetry (DSC) and thermal gravimetric analyses (TGA) were highly thermally stable, up to 312oC.  These glycerides can be employed in a myriad of commercial uses such as packaging materials, extruded bioplastics etc.

A METHOD FOR THE SYNTHESIS OF 2-UNDECANONE

Ketones may be produced in high yields from glycerides of short chain fatty acids by reaction with a carboxylic acid.  The reaction is conducted in the presence of a catalyst and under conditions effective for ketonization of decanoate with the carboxylic acid to produce free ketones. Reaction of a glyceride comprising at least one ester of decanoic acid with a carboxylic acid selected from acetic acid and/or propionic acid produces 2-undecanone and/or 3-dodecanone, respectively.  Catalysts of the formula FemCenAlpOx, wherein m is between about 0.2 to about 0.6, n is about 0.2, p is between about 0.6 to about 0.2, and x is greater than 0, produce significantly higher yields of the ketones than other known metal oxides.
