A liquid concentrate comprising essentially:

Protection of liquid fuels

A lubricant composition includes a base oil and a cyclic amine compound. A method of lubricating a system including a fluoropolymer seal with the lubricant composition is also provided. An additive concentrate for a lubricant composition is also provided. The cyclic amine compound is useful for adjusting the total base number of a lubricant composition. The lubricant composition is compatible with fluoropolymer seals.

Lubricant composition comprising hindered cyclic amines

A lubricant composition including an acyclic amine compound. A method of lubricating a system including a fluoro-polymer seal with the lubricant composition is also provided. An additive concentrate for a lubricant composition is also provided. The acyclic amine compound is useful for adjusting the total base number of a lubricant composition. The lubricant composition is compatible with fluoropolymer seals.

Lubrican composition comprising acyclic hindered amines

Preparation of bifunctional polyisobutenes in which isobutene or an isobutene-containing monomer mixture is polymerized in the presence of a Lewis acid and a compound of the formula I in which X is an acyl radical or the radical of an organic or inorganic acid group, Rto Rare identical or different and are hydrogen or a hydrocarbon radical.

Process for preparing polyisobutenes

Preparation of high-reactivity isobutene homo- or copolymers with a content of terminal vinylidene double bonds per polyisobutene chain end of at least 50 mol % and a polydispersity of preferably 1.05 to less than 3.5, by polymerizing isobutene or an isobutene-comprising monomer mixture in the presence of an aluminum trihalide-donor complex effective as a polymerization catalyst or of an alkylaluminum halide-donor complex, especially of an aluminum trichloride-donor complex, said complex comprising, as the donor, an organic compound with at least one ether function or a carboxylic ester function.

Process for preparing high-reactivity isobutene homo- or copolymers

The present invention relates to antifreeze/anticorrosion concentrates comprising from 10 to 50% by weight, based on the total amount of the concentrate, of glycerol, to processes for preparing such concentrates from superconcentrates, to aqueous coolant compositions from these concentrates, and to their use, for example in internal combustion engines.

Glycerin-containing antifreezing agent concentrates with corrosion protection

The present invention relates to a process for preparing trioxime derivatives of the formula Iin which the substituents Rand Rare identical or different and each is cyano, alkyl, haloalkyl or cycloalkyl, and Rand Rare identical or different and each is alkyl, haloalkyl, cycloalkyl, alkylcarbonyl or arylalkyl, by the following reaction steps in water without isolation of the intermediates:

Method for the production of trioxime derivatives

Continuous preparation of dimethylvinylcarbinol by isomerizing prenol

Allyl alcohols are isomerized in aqueous solution in the presence of protonic acids, with the pH of the reaction mixture being adjusted to the range from 2 to 5 with an acid concentration below 0.16 mol per liter of the reaction mixture or with a buffer which comprises the protonic acid.
