Abstract:
The present invention relates to functional fluid compositions containing antioxidants, and specifically stable compositions containing antioxidants with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and antioxidants containing a phenolic or benzoic group, where the antioxidant is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.
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:
PROBLEM TO BE SOLVED: To provide a fuel additive containing ferrocene and/or a ferrocene derivative that can be easily and stably dissolved in a fuel. SOLUTION: The fuel additive contains ferrocene and/or a ferrocene derivative and lecithin. The fuel additive in a solid form comprises 80-99 mass% of ferrocene and/or a ferrocene derivative and 1-20 mass% of lecithin. The fuel additive in a granular form comprises 78-99 mass% of ferrocene and/or a ferrocene derivative, 0.9-20 mass% of lecithin, and 0.1-2 mass% water. The fuel additive in a liquid form comprises a mineral oil in which ferrocene and/or a ferrocene derivative and lecithin are dissolved, provided that the amount of the ferrocene and/or the ferrocene derivative contained is 2-5 mass%, and the amount of lecithin is 5-50 mass%. The fuel additive is used so that the concentration of the ferrocene and/or the ferrocene derivative in the fuel is 1-50 ppm, and the concentration of lecithin is 0.01-500 ppm.
