Abstract:
A process of bleaching carboxylic acid esters and/or epoxy compounds by irradiating the esters and/or epoxy compounds with ultraviolet light in the presence of a peroxy compound. The preferred compounds bleached are the epoxidized higher fatty acid esters. Hydrogen peroxide and peracetic acid are examples of suitable peroxy compounds.
Abstract:
AN EPOXIDIZED FATTY ACID ESTER OF A CYCLIC POLYOL SUCH AS THAT OF THE FORMULA:
R1-COO-CH2-C(-CH2-O-X) WHEREIN:
X IS H OR
-CO-R1
Y IS -O-, -S-, OR -CH2-, R1 IS EPOXIDIZED FATTY RADICAL, SUCH AS THOSE DERIVED FROM TALL OIL FATTY ACIDS. A COMPOSITION OF METTER COMPRISING THE ABOVE APOXIDIZED FATTY ESTERS AND AN ACIDIC POLYESTER. THESE COMPOSITIONS OF MATTER ARE USEFUL AS COATING COMPOSITIONS AND PAINT SUBSTITUTES, WHEN APPLIED TO SUBSTRATES.
Abstract:
A process of bleaching carboxylic acid esters and/or epoxy compounds by irradiating the esters and/or epoxy compounds with ultraviolet light in the presence of ketone. The preferred compounds bleached are the epoxidized higher fatty acid esters. Benzophenone, acetophenone, and acetone are examples of some suitable ketones.
