Abstract
Process for the manufacture of an antimicrobial product, consisting essentially of the neutralization reaction of d- (2-amino-2-phenylacetamido) -3,3-dimethyl-7-oxo-4-thio-l-azobicyclo [3.2] .0] heptane-2-carboxylic acid (which will be hereafter called the main acid, in order to abbreviate its mention), either anhydrous or with 1 to 6 molecules of water, and subsequent solubilization in aqueous medium of said acid by means of sodium hydroxide in the presence of a substance of pka between 5 and 13, or directly by the sodium salt of this substance of pka between 5 and 13, using in any case a solvent immiscible with water to extract the weak acid released, recovering the sodium salt of the main acid by elimination of water.
