Zusammenfassung:N-(4-chlorobenzoyl)- and N-(2,4-dichlorobenzoyl)-cephalosporin C values are useful in processes for separating the cephalosporin C values for polysaccharide and proteinaceous impurities present in fermentation liquors. These new intermediates can be used as starting materials in cleavage processes for forming 7-amino-cephalosporin values, and the 7-amino cephalosporin values can be used form cephalosporin antibiotics such as cephalothin, cephaloridine, and cephalexin.
