Abstract:
The present invention relates to the field of processing hydrocarbons which causes corrosion in the metal surfaces of processing units. The invention addresses the technical problem of high temperature naphthenic acid corrosion and sulphur corrosion and provides a solution to inhibit these types of corrosion. The three combination compositions are formed by two mixtures separately, with one mixture obtained by mixing compound A, which is obtained by reacting high reactive polyisobutylene (HRPIB) with phosphorous pentasulphide in presence of catalytic amount of sulphur with compound B which is thiophosphorous compound such as phosphorous thioacid ester of Formula 1 and second mixture obtained by mixing compound A with compound C of Formula 2 which is obtained by reacting compound B with ethylene oxide, wherein each of these two mixtures independently provide high corrosion inhibition efficiency in case of high temperature naphthenic acid corrosion inhibition and sulphur corrosion inhibition. The invention is useful in all hydrocarbon processing units, such as, refineries, distillation columns and other petrochemical industries.

Abstract:
A method[ of improving the efficiency of a fuel for an internal combustion engine, which fuel comprises lubricating oil and gasoline, which comprises adding to the lubricating oil or the fuel cerium oxide and/or doped cerium oxide.
Abstract:
Lubricants, especially lubricating oils, and fuels, especially hydrocarbon fuels, contain a class of anti-wear, and extreme pressure additives that are derived from silanes. The additives can be used as either partial or complete replacements for zinc dialkyldithiophosphates currently used in lubricant and fuels.
Abstract:
Reaction products of 5-norbornene-2,3-dicarboxylic anhydride O,O-dialkyldithiophosphate adduct of the formula (I) have been found to be beneficial additives for functional fluids used in the machinery of motorized vehicles. These additives are effective extreme pressure agents and antiwear agents as well as antioxidants for use in such functional fluids as lubricating oils including automatic transmission fluids and hydraulic fluids.
Abstract:
Adducts of formula (I) have been found to be additives for functional fluids. These additives are effective extreme pressure agents and antiwear agents as well as antioxidants for use in such functional fluids as lubricating oils including automatic transmission fluids and hydraulic fluids. Wherein R is, independently, alkyl or aryl and X and Y are the same or different and are hydrogen, carboxy, hydrocarbyl carboxy, cyano, aldehyde, hydrocarbyl keto, N-substituted carboxamide, thio- or dithiocarbamate, thioamide, thioacid or ester, a hydrocarbyl phosphorus containing radical, together are dicarboxylic anhydride or imide or N-hydrocarbyl substituted imide. Some of these adducts are considered to be new.
