IN A PROCESS FOR THE PREPARATION OF A SUPERALKALINIZED CALCIUM SULPHONATE ARE USED PROMOTERS CAPABLE OF INCREASING THE EFFICIENCY OF THE CONVERSION OF LIME TO A DISPERSION OF CALCIUM CARBONATE SOLUBLE IN OILS. THE PROCESS CONSISTS OF CONTACTING AN ACIDIC GAS IN CONTACT WITH A MIXTURE OF SULPHONIC ACID OR A CALCIUM SALT OF THE SAME, A HYDROCARBON SOLVENT, CALCIUM HYDROXIDE, A LOW QUANTITY OF METHANOL AND A MAXIMUM OF 1 BY WEIGHT OF A PROMOTER IN THE FORM OF A CYCLIC COMPOUND WITH PENTAGONAL CORE. AMONG THE PREFERRED COMPOUNDS OF THIS KIND ARE IMIDAZOLINES, OXAZOLINES AND PYRROLES. |
