The present invention describes alkoxylated amines as fuel additives for reducing injector deposits in direct injection gasoline engines.

Alkoxylated amines as fuel additives

Novel uses of copolymers for removing and/or reducing the level of deposits in the fuel system and/or injection system of direct injection diesel and/or gasoline engines are provided. What is provided is the use of particular copolymers as fuel additive or lubricant additive; to processes for preparation of such additives, and fuels and lubricants added therewith, such as, more particularly, as a detergent additive; to use of these copolymers for reducing the level of or preventing deposits in the fuel systems and especially the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.

Copolymers as additives for fuels and lubricants

The present invention relates to novel uses of corrosion inhibitors in fuels and lubricants.

Polymers as additives for fuels and lubricants

An improved process is proposed for preparing cyclocarbonate-functionalized compounds of the general formula (I) where Rand Rin each occurrence are independently selected from hydrogen, methyl and ethyl, l in each occurrence independently is from 2 to 50, m in each occurrence independently is 0 or 1, and n is =3, subject to the proviso that the sum of all l values in the molecule is from 5 to 100, by reacting a chloroformate of formula (II) with a trifunctional amine of the general formula (III) characterized in that the reacting is carried out in an aqueous/organic two-phase system in the presence of an auxiliary base and of a phase transfer catalyst.

Preparing cyclocarbonate-functionalized compounds

A water-dispersible, cyclocarbonate-functionalized vinyl copolymer binder, a process for the preparation of the binder, an aqueous dispersion containing the binder, a system comprising the binder, water and an (amine) curing agent and the use of the binder for the production of a hardened coating are proposed. It was surprisingly found that this binder, in which the emulsifier groups according to the invention are incorporated in the polymer chain, gives stable aqueous dispersions having a solids content of up to a 30% by weight.

Water dispersable, cyclic-carbonate-functionalized vinyl copolymer system

Proposed are 2-oxo-1,3-dioxolane-4-carboxylic acid and derivatives thereof, according to the following formula, in which Rrepresents a negative charge, hydrogen or can be preferably Me or Et or a radical having a valency of 2 to 5, which is substituted with an amount of further 2-oxo-1,3-dioxolane-4-carboxyl groups equal to the radical valency minus 1, as well as a process for their preparation by means of carboxylation of the corresponding epoxides, a process for their transesterification and their use for the preparation of hydroxyurethanes and as end groups for the blocking of amines.

2-oxo-1, 3-dioxolane-4-carboxylic acid and derivatives thereof, their preparation and use

The invention relates to a method for removing water from a mixture containing at least one compound having at least one group reactive towards isocyanate and containing water, the mixture being applied to the surface of a rotating body A, the mixture flowing over the surface of the rotating body A to an outer region of the surface of the rotating body A and water evaporating from the mixture. In particular, this method is suitable for removing water from alcohols and amines.

Method for removing water from a mixture

The invention relates to a process for the preparation of polymers by free radical polymerization of monomers in the presence of water, electrochemically produced free radicals being used for initiating the free radical polymerization.

Method for initiating radical polymerizations

The invention relates to a process for the preparation of a copolymer by free radical mass polymerization of a maleic acid monoester derivative with vinyl ester in the presence of an acid having a pKa of less than 1.8. The copolymer is suitable as a dispersant for hydraulic binders.
