separation from an organic solution of tetraheptylammonium chloride may be accomplished by extraction with water under the following conditions , which promote transfer of a glucosiduronate to the aqueous phase : ( 1 ) an appropriate solvent ( diluent ) as the organic phase , ( 2 ) the presence in the two-phase mixture of an anion such as myristate or dodecyl sulphate to combine with the tetraheptylammonium ion , and ( 3 ) an increase of the ph of the aqueous phase in association with the presence of myristate or dodecyl sulphate .
