Summary
The objective of the program is to define the possible uses of the by-products of coal conversion processes (CCP). In the initial phase of the program a process was developed for the oxidation of certain by-products, i.e., chars and tars to benzene carboxylic acids (BCA). In the second phase of the program the study of the oxygen oxidation of COED Western Kentucky filtered oil in aqueous sodium carbonate was completed. The oxidation yielded a mixture of organic acids composed mainly of oxalic acid and BCA. The optimum yield of BCA was 23.5 g/100 g feed. This yield was obtained using the following conditions; time, 45 min; temperature, 270/sup 0/C; total pressure, 1400 psi; carbonate to feed ratio, 4; percent carbonate, 8 percent. In addition, oxalic acid, 4.2 g, was also isolated. This brings the yield of marketable acids to Ca. 28 percent and accounts for Ca. 80 percent of the organic extract, the organic acids obtained in the oxidation. An economic analysis of the various uses of the chars and heavy tar residues was made to determine the most economical use of these by-products. It did show that the most economic use of the chars and tars was the combined production of terephthalic acid and detergent builders. The study also showed that the chemical markets would be greatly disrupted if these by-products were used to produce only one or two chemical products. The conversion of the mixture of BCA to terephthalic acid using Henkel reaction conditions was also studied. This work is still underway.
