PROCESS FOR THE PREPARATION OF ORGANO-SOLUBLE COMPLEXES OF CALCIUM, COMPLEXES OBTAINED AND THEIR USE, E.G. AS ADDITIVES FOR IMPROVING THE BURNING OF GAS OILS AND FUEL OILS

摘要

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 C3 or C4 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.
