摘要:
An organomodified silicone material is shown and described herein. The organomodified silicone provides a material that can be used as an additive in a fuel oil, e.g., diesel fuel. The organomodified silicone acts as both a defoamer and a dehazer in a fuel oil.
摘要:
A method for reducing the propensity of a fuel to form an emulsion comprises combining an additive having a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon with the fuel. Thus, the additive may be used as a demulsifier in a fuel.

Verwendung von mehrkernigen phenolischen Verbindungen mit bis zu 20 Benzolkernen pro Molekül, welche durch Umsetzung eines Tetrahydrobenzoxazins I wobei R 1 einen Hydrocarbylrest bezeichnet und R 2 , R3, R 4 und R 5 unabhängig voneinander für Wasserstoffatome, Hydroxylgruppen oder Hydrocarbylreste stehen, mit einem oder mehreren der gleichen oder verschiedener Phenole II wobei R 7 , R 8 , R 9 und R 10 unabhängig voneinander für Wasserstoffatome, Hydroxylgruppen oder Hydrocarbylreste stehen, und/oder mit einem oder mehreren der gleichen oder verschiedener Tetrahydrobenzoxazine I erhältlich sind, mit der Maßgabe, dass mindestens einer der Substituenten 13 bis 3000 Kohlenstoffatome aufweist und die übrigen Substituenten, wenn sie für Hydrocarbylreste stehen, jeweils 1 bis 20 Kohlenstoffatome aufweisen, als Stabilisatoren zur Stabilisierung von unbelebtem organischen Material gegen die Einwirkung von Licht, Sauerstoff und Wärme.
摘要:
Disclosed are cloud point depressants and methods of making and using them. The disclosed cloud point depressants comprise copolymers of a maleic moiety polymerized with alpha olefins and then contacted with an aliphatic tertiary amine to provide a cloud depressant reaction product. When the disclosed reactions products are added to middle distillate fuels or blends of middle distillate fuels with biodiesel, the cloud point depressants inhibit the precipitation of waxes and/or biowaxes in the fuels and the fuels exhibit reduced precipitation, gelling, and/or crystallization when subjected to low or cold temperatures.

A Fuel additive concentrate comprising the said hydrocarbyl-substituted dicarboxylic acid, certain additives with detergent action and optionally other customary additives and solvents or diluents.
摘要:
Use of a reaction product of saturated or unsaturated aliphatic mono- or polycarboxylic acids with aliphatic polyamines for improving or boosting the separation of water from fuel oils which comprise additives with detergent action. A Fuel additive concentrate comprising the said reaction product, certain additives with detergent action and optionally dehazers, cetane number improvers and solvents or diluents.
摘要:
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.
摘要:
