    Abstract: A process for purification of crude clavulanic acid and its subsequent conversion to its potassium salt. A crude clavulanic acid extract is contacted in an organic solvent with an alkylenediamine of the formula II ##STR1## wherein the substituents R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each individually denote a hydrogen atom, or a straight chain or a branched chain alkyl group having 1 to 8 carbon atoms, R.sub.5 denotes a hydrogen atom, and n denotes an integer 1. The thus obtained alkylenediammonium diclavulanates of the formula I are isolated ##STR2## wherein the substituents R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 and n have the meanings as defined at formula II. Salts of the alkylenediammonium diclavulanate of the formula I are converted with potassium 2-ethyl-hexanoate in isopropanol into potassium salt of clavulanic acid.

    Abstract: A di-clavulanate salt derived from clavulanic acid and a diamino ether of the formula ##STR1## wherein R.sup.1 is an alkylene group, optionally having one or more inert substituents: and each of R.sup.2 and R.sup.3 is a hydrogen atom or an alkyl group, optionally having one or more inert substituents, or R.sup.2 and R.sup.3 together complete a heterocyclic ring having four to seven carbon atoms, again optionally having one or more inert substituents. A process for preparing the clavulanic acid salt includes the steps of preparing a substantially water free solution of clavulanic acid, or a salt thereof, in an organic solvent which solution is at a maintained temperature of 0.degree. to 15.degree. C. and then reacting the clavulanic acid, or salt thereof, with diamino ether in the organic solvent.
