PRODUCTION OF A SALT OF CLAVULANIC ACID

摘要

Process for the production of alkali salts of clavulanic acid of for-mula (I) by conversion of clavulanic acid into a pharmaceutically accept-able salt of clavulanic acid which is characterised in that the conver-sion is carried out in n-butanol or iso-butanol (2-methyl-1-propanol) as a solvent; and a potassium salt of clavulanic acid containing n-butanol or iso-butanol.
