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:
A method of affecting soot particulate size in an internal combustion engine exhaust by selectively providing a phosphorous based additive to the engine during combustion. Soot particulate size can be increased or decreased depending on the particular additive provided. Also disclosed in a conditioning effect experienced by using a phosphorous based additive for a period of time. A conditioned engine can also have its exhaust properties affected during the life of its conditioned state. Manipulating particle size during engine operation can employ an oligomeric phosphorous compound. Engine conditioning can employ a monomeric phosphorous containing compound, an oligomeric phosphorous containing compound, a polymeric phosphorous containing compound, or combinations thereof.
Abstract:
A fuel additive contains ferrocene and/or ferrocene derivative(s), and lecithin. A fuel additive contains 80 to 99 mass % of ferrocene and/or ferrocene derivative(s), and 1 to 20 mass % of lecithin, and being in the solid state. A fuel additive contains 78 to 99 mass % of ferrocene and/or ferrocene derivative(s), 0.9 to 20 mass % of lecithin and 0.1 to 2 mass % of water, and being in the particle state. A fuel additive containing 2 to 5 mass % of ferrocene and/or ferrocene derivative(s), 5 to 50 mass % of lecithin and mineral oil, and being in the liquid state, wherein the ferrocene and/or ferrocene derivative(s), and the lecithin are dissolved in the mineral oil. The above-mentioned fuel additive is used by being added into a fuel so as to make the concentration of the ferrocene and/or ferrocene derivative(s) and the lecithin in ranges of 1 to 50 ppm, and 0.01 to 500 ppm, respectively.
Abstract:
Novel substituted phosphazene compounds are disclosed having the formula ##STR1## wherein w, x, y and z are integers the sum of which is from 3 to 6 with the proviso that w is at least 1 but equal to or less than (w+x+y+z)-1, x is from 1 to 5, y and z are from 0 to 2;R.sub.1 and R.sub.2 are the same or different and are C.sub.1 to C.sub.6 linear or branched alkyl;R.sub.3 is an unsubstituted or substituted aryl and n is 0 or an integer from 2 to 6; Q is --O--, ##STR2## --NR-- or --S--; Ar is ##STR3## R' and R" are the same or different and are C.sub.1 to C.sub.6 linear or branched alkyl, with the proviso that R" can also be hydrogen, wherein R.sub.1 and R.sub.2 are the same or different C.sub.1 to C.sub.4 linear or branched alkyl group and n is 0 or an integer from 2 to 6. These compounds display good solubilities in both organic and aqueous systems. Accordingly, they act as antioxidants in adhesive, sealant and coating compositions.
