LA PRESENTE INVENTION EST RELATIVE A UN PROCEDE DE PREPARATION D'ADDITIFS EXTREME-PRESSION.L'ADDITIF REPOND A LA FORMULE GENERALE:(RI-VAR)(S)DANS LAQUELLE:R, R... R REPRESENTENT L'HYDROGENE, DES GROUPES D'HYDROCARBURES COMPORTANT 1 A 40ATOMES DE CARBONE;AR REPRESENTE DES GROUPES D'HYDROCARBURES AROMATIQUES COMPORTANT 1 OU PLUSIEURS NOYAUX;B 1 A 5, C 2 A 10, D 1 A 9, ET X 1 A 6 ET EST PREPARE EN FAISANT REAGIR DES COMPOSES ORGANIQUES CHLORES DE FORMULE (RI-V-AR)-CL, SUR DES SULFURES METALLIQUES DE FORMULE MS ET EN CHLOROMETHYLANT DES HYDROCARBURES DE FORMULE RI-V-AR AVEC UNE SOLUTION DE FORMALDEHYDE ET DE L'ACIDE CHLORHYDRIQUE.APPLICATION : PREPARATION D'HUILES LUBRIFIANTES ET HYDRAULIQUES. Extreme pressure (EP) additives of the general formula (R-Arb)c(Sx)d, wherein R, R, R, R and R are the same or different and each represents a hydrogen atom, a C1-40 straight or branched chain or cyclic, saturated or unsaturated hydrocarbyl group or a derivative thereof; Ar stands for a monocyclic or polycyclic aromatic hydrocarbyl group or a derivative thereof; b means a number from 1 to 5; c means a number from 2 to 10; d means a number from 1 to 9; and x means a number from 1 to 6, are useful for the preparation of auxiliary materials for lubricating and hydraulic oils, lubricating greases as well as for metal-working coolant and lubricating fluids.
