Method for preparing certain oximes and oxime O-methyl ethers by reacting poorly water-soluble carbonyl compounds with salts of hydroxylamine or hydroxylamine O-methyl ether or the free base of hydroxylamine in the presence of certain phosphoric esters or salts thereof of the formula (I) wherein R, Rand X are defined as specified in the description.

Method for producing specific oximes and oximethers

The present invention relates to a process for preparing dithiinetetracarboximides by reaction of succinic monoamides with thionyl chloride, with continuous performance of at least one of the process steps.

Method for producing dithiine tetracarboximides

The invention relates to a process for esterifying free fatty acids in vegetable and animal fat with alcohols over heterogeneous acidic ion exchange resin catalysts at temperatures of 60 to 120&#xb0; C.

Process for heterogeneously catalysed esterfication of fatty acids

Continuous method for the esterification of free fatty acids in plant and animal fats with alcohols using a heterogenic acid catalyst.

Continuous method for the heterogenically catalyzed esterification of fatty acids

The invention relates to a semibatchwise process for the mild distillative separation of mixtures, in a first stage a column being supplied continuously with a feed and the feed being separated at least into different fractions, one of the fractions being removed continuously into a container, and, in a second step, the fraction removed into the container being recycled to the column and being separated again batchwise into different fractions.

Process for the mild distillative separation of mixtures

The invention relates to a novel process for preparing fluorosulfonic acid having low contents of low-boiling compounds in which hydrogen fluoride and sulfur trioxide are combined in stoichiometric amounts in a reaction vessel or by means of a reaction nozzle, the hot, gaseous fluorosulfonic acid that is formed is fed directly into a distillation column, and the fluorosulfonic acid is taken off at the bottom of the column or in the stripping section of the distillation column.

Process for preparing fluorosulfonic acid having low contents of low-boiling compounds

The present invention relates to a process for preparing phosphoric acid esters, in particular a process for preparing monomeric bridged bisaryl diphosphates, wherein a water-binding agent is added to the reaction solution.

Process for preparing phosphoric acid esters

The present invention relates to a process for preparing phosphoric acid esters, in particular monomeric bisaryl diphosphates, or bridged phosphates.

A process for the preparation of nicotinic acid by the direct oxidation of &bgr;-picoline in the gas phase, wherein water and &bgr;-picoline are fed separately to the catalyst bed and the catalyst is based on a titanium dioxide support which has been prepared by the sulfate method and has a high specific surface area and a vanadium oxide content of from 5 to 50 %.
