SYNTHESIS PROCESS FOR THE PRODUCTION OF QUARTERNARY CATIONIC SALTS THAT ARE USEFUL AS CHEMICAL TRACERS IN CARBONATE RESERVOIRS, AND PRODUCTS PRODUCED WITH SAME

摘要

The invention relates to a process for the production of organofluoride quarternary cationic salts, comprising the following steps: a) adding a base; b) suspending the base in a suitable polar organic solvent; c) including an alkylating agent via slow addition; d) slowly adding an organofluoride substrate; e) heating the reaction mixture produced in the preceding step d); f) bringing the reaction mixture to ambient temperature; g) filtering the reaction mixture under vacuum, washing the remaining solid with a polar organic solvent; h) accelerating the evaporation of the solvent to complete dryness, producing a whitish solid; i) washing the solid with a non-polar organic solvent; j) purifying the compound produced in the preceding step i), using a polar or non-polar organic solvent, wherein the cationic salts produced with this method are used as chemical tracers to determine the heterogeneity in carbonate-type oil fields.
