Abstract:
The invention relates to the use of a hydrophobin or a derivative thereof as an antifoaming agent in additive compositions or in fuels, to a method for defoaming fuels, to an additive and fuel composition containing a hydrophobin or derivative thereof and at least one additional fuel additive, and to a method for producing a fuel composition.
Abstract:
The invention relates to fuel additive compositions for internal combustion engines and to fuels that contain the corresponding additives for internal combustion engines. The inventive fuel additive compositions for internal combustion engines have an excellent performance in keeping the inlet system clean and improved viscosity properties, especially at low temperatures.
Abstract:
The invention relates to a method for producing 2-alkyl polyisobutenylphenols and their Mannich adducts, to compositions that are obtained according to said method and to the use of said compositions.
Abstract:
The invention relates to the use of polynuclear phenolic compounds with up to 20 bezene nuclei per molecule, obtained by reaction of a tetrahydrobenzoxazine I, where R 1 = a hydrocarbon group and R 2 , R 3 , R 4 and R 5 independently = H, OH, or hydrocarbon groups, with one or more of the same or different phenols II, where R 7 , R 8 , R 9 and R 10 independently = H, OH or hydrocarbon groups and/or with one or more of the same or different tetrahydrobenzoxazines I, with the proviso that at least one of the substituents has 13 to 3,000 carbon atoms and the remaining substituents, when hydrocarbon groups, have 1 to 20 carbon atoms, as stabilisers for stabilising inanimate organic materials against the effects of light, acid and heat.
Abstract:
The invention concerns fuel or lubricant additives based on the reaction products of an ethylenically unsaturated poly-1-alkene derived from one or more 1-alkenes with 3 to 24 carbon atoms and 0 to 50% by wt. of ethene, as well as a method of producing the additives and fuel and additive compositions containing such additives.
Abstract:
The invention relates to the use of polymers which comprise, in copolymerized form, an alpha-olefin, an alkenyl ester of a carboxylic acid and an ester of an alpha,beta-unsaturated carboxylic acid as an additive for turbine fuels and in particular as a cold flow improver for turbine fuels, to the turbine fuels additized with these polymers, and to additive packets comprising such copolymers.

Abstract:
The invention relates to the use of at least one protein, especially at least one hydrophobin or at least one derivative thereof, for improving the phase separation in compositions containing at least two liquid phases. The invention also relates to a method for separating at least two liquid phases in a composition containing at least two liquid phases, and formulations containing at least one compound selected from the group consisting of fuels, combustibles, crude oil or water-soluble or oil-soluble polymer solutions, and at least one protein, especially at least one hydrophobin or derivatives thereof.
Abstract:
The invention relates to novel fuels for Otto engines, containing a synergistically acting mixture of a detergent additive component (A) and a synthetic carrier oil component (B). Said detergent additive component (A) forms at least one bond with a basic nitrogen atom which is substituted with a hydrocarbyl radical having an average numerical molecular weight of about 500 to 1300, the detergent additive component (A) being contained in the fuel at a ration of about 30 to 180 ppm by weight. The carrier oil component (B) consists of at least one compound of general formula R-O-(A-O) X -H(I), in which R represents a linear or branched C6-C18 alkyl group, A represents a C3 or C4 alkyl group, and X represents an integer value of 5 to 35, said carrier oil component (B) being contained in the fuel at a ratio of about 10 to 180 ppm by weight.
