Abstract
CONCRETEALLY, THE ALKALINE SALTS OF ESTERESA HYDROXY-STEROID DULPHURICS, OF STUCTURAL FORMULA (I), WHERE M IS SODIUM OR POTASSIUM AND R IS A RADICAL FROM A HYDROXY-STEROID OF GENERAL FORMULA (II), WHERE R1 REPRESENTS A KETONE OR A HIDROXI GROUP AND R2 REPRESENTS A KETONE. UNDERSTAND THE FOLLOWING STAGES: FIRST, A STEROID COMPOUND OF GENERAL FORMULA (II) IS REACTED WITH CHLOROSULPHONIC ACID, ADDING IN A SLOW WAY AND WITH STRONG AGIATATION, FOR THE FORMATION OF PIRIDINE-TRIOXIDE REAGENT; SECOND, THE PRODUCT OF THE SECOND STAGE IS SUBJECTED TO A SULPHONATION THROUGH THE ADDITION OF THE HYDROXIDE-STEROID, AND FOLLOWING, KEEPING THE SUSPENSION IN CONSTANT AGITATION, SLOWLY ADDING STERILE-TRIETHYL-ESTIRATE: -SO3-PY, WHERE R IS THE STEROIDAL RADICAL; THIRD, IN THE PRODUCT RESULTING FROM THE SECOND STAGE, A SUBSTITUTION IS PRODUCED, THROUGH THE ADDITION OF A CONCENTRATED SOLUTION.
