A process for preparing a cephalosporin salt substantially insoluble in water but dispersible in water, which is characterized by mixing, in an aqueous medium, a water soluble salt of an amine selected from the group consisting of trans-1,3- and trans -1,4-cyclohexane diamine trans-1,3- and trans-1,4-cyclohexane (alkylaminoamine) having from 1 to 3 carbon atoms in the alcohol group, and 1,3- and 1,4-xylene-alpha, alpha'-diamine, with a water-soluble form of cephalosporin of the formula ** (see formula) ** Wherein r is selected from the group consisting of 2-thienylmethyl, 2-furylmethyl, phenylmercaptomethyl, benzyltrifluoromethylphenylmercaptomethyl and nitrobenzyl, and r'is selected from the group consisting of hydrogen and acetoxy, to form a salt substantially insoluble in water, and collecting the salt thus obtained.
