A process for the removal of acids from reaction mixtures, comprising at least one product of value which is sparingly soluble in water, by at least one unpolar amine as an auxiliary base, which includes: a) reacting the auxiliary base with the acid with formation of a salt; b) reacting the salt formed in step a) with a further base which accepts the acid with liberation of the auxiliary base and combines with the acid to be accepted from the auxiliary base to form a salt which is very readily soluble in water; c) extraction of the mixture obtained in step b) with water or an aqueous medium, wherein the salt of the further base dissolves in the aqueous phase and the product of value, or the solution of the product of value, in a suitable solvent and the auxiliary base form at least one separate nonaqueous phase; and d) removal by distillation of at least part of any solvent present from the at least one nonaqueous phase obtained in step c), to form two nonmiscible liquid phases.

Method of separating acids from chemical reaction mixtures by means of apolar amines

The invention relates to a process for purifying an ionic liquid, which comprises the steps (a) partial crystallization of the ionic liquid from its melt and (b) separation of the crystals from the residual melt.

Purification of ionic liquids

The invention relates to a process for the preparation of triamides from ammonia and amido-dichlorides.

The invention relates to preparations with improved urease-inhibitory effect which comprise at least two different (thio)phosphoric triamides and to urea-comprising fertilizers which comprise these preparations. The invention furthermore relates to a method of preparing these preparations, to the use of these preparations in the fertilization with urea-comprising fertilizers, and to the use of urea-comprising fertilizers which comprise these preparations in agriculture or in horticulture.

Preparations with improved urease-inhibiting effect and urea-containing fertilizers containing the latter

The invention relates to a method of operating a liquid ring compressor having an impeller installed eccentrically in a compressor body, with gas being supplied to the liquid ring compressor on a suction side and gas being discharged from the liquid ring compressor on a pressure side. A liquid ring is generated in the liquid ring compressor on the inside of the compressor body by rotation of the impeller. Chambers are formed between blades of the impeller and the liquid ring and gas is drawn into these. The gas is compressed in the chambers which become smaller from the suction side to the pressure side as a result of the rotation of the eccentrically mounted impeller. The compressed gas is ejected on the pressure side. An ionic liquid is used as service liquid for generation of the liquid ring.

Process for preparing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphorous ester diamides, aminophosphines, diaminophosphines, phosphorous ester amide halides and aminophosphine halides with elimination of an acid in the presence of an auxiliary base, wherein the auxiliary base

Method for the separation of acids from chemical reaction mixtures by means of ionic fluids

A process for removing acids from reaction mixtures using an auxiliary base, in which the auxiliary base: combines with the acid to form a salt which is liquid at temperatures at which the product of value does not significantly decompose during the removal of the liquid salt, and the salt of the auxiliary base with the product of value or the solution of the product of value in a suitable solvent forms two immiscible liquid phases.
