Abstract
Soluble organic calcium complexes are prepared by (a) reacting a sulfonic acid with an excess of calcium oxide or hydroxide over the stoichiometry in a liquid medium comprising a hydrocarbon or a halohydrocarbon, methanol and a C.sub.3 or C.sub.4 alcohol, in the presence of a nitrogen compound having a long hydrocarbon chain, (b) reacting the resultant product with carbon dioxide and (c) recovering the resultant calcium complex.
