Method for reacting an organic compound with a hydroperoxide

Process for the preparation of a crystalline solid comprising at least one zeolitic material, in which the solid is crystallized from at least one precursor compound and the reaction discharge of the crystallization is fed directly to a drying stage.

Preparation of a crystalline, zeolitic solid

An organic compound having at least one C&#x2014;C double bond is epoxidized by means of hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, wherein a product mixture comprising &#x3b1;-hydroperoxyalcohols is reduced using at least one reducing agent. The process advantageously comprises at least the following steps:

Method for producing an epoxide

A process for the regeneration of a zeolite catalyst which comprises treating the catalyst thermally in the presence of a gas stream at temperatures above 120&#xb0; C., the weight-based residence time of the gas stream over the catalyst during the thermal treatment being greater than 2 hours.

Method for regenerating a zeolite catalyst

A process for preparing propylene oxide comprises at least the following steps:

Method for producing propylene oxide

A process for the preparation of propylene oxide in the presence of methanol, in which propylene oxide is separated from a mixture propylene oxide and methanol, and the resultant methanol containing mixture is worked up, including seperating methanol from a mixture comprising methanol and methyl formate during the work-up.

Method for the production of propylene oxide

Method for producing crystalline, zeolitic solid matter

The use of inorganic or organic polyacids for the treatment of inorganic fertilizers, in particular the use of the polyacids as a mixture with at least one nitrification inhibitor for the treatment of inorganic fertilizers; the use of selected pyrazole derivatives as nitrification inhibitor in inorganic fertilizers and also as stabilizers of liquid manure or liquid fertilizer formulations, as well as the corresponding treated inorganic fertilizers per se; and novel pyrazole derivatives which can be used as nitrification inhibitors in inorganic fertilizers and also as stabilizers of liquid manure or liquid fertilizer formulations are described.

Nitrification inhibitors, and the use of polyacids which contain a nitrification inhibitor for the treatment of inorganic fertilizers

A process for regenerating a zeolite catalyst comprises thermal treatment of the catalyst at above 120&deg; C. in the presence of a gas stream comprising hydrogen.

A process for preparing glycol monoethers from olefins comprises reacting the olefins with an epoxidizing reagent in the simultaneous presence of hydroxyl-containing organic compounds over a mixture of epoxidation catalysts and alkoxylation catalysts.

Single-stage process for preparing glycol monoethers from olefins

In a continuous process for reacting an organic compound with hydroperoxide in the presence of a catalyst, the reaction is carried out in a reactor assembly comprising at least two reactors connected in parallel.

Method for converting an organic compound with a hydroperoxide

A mixture (M1) comprising an alkene and oxygen is worked up by a process in which (i) oxygen is removed from the mixture (M1) by a nondistillative method to give a mixture (M2) and (ii) the alkene is separated off from the mixture (M2) by distillation.

Working up a mixture comprising alkene and oxygen

Method for regenerating a zeolitic catalyst

In a process for reacting an organic compound with a hydroperoxide using at least one heterogeneous catalyst, both the pH and the temperate of the reaction medium are changed during the reaction
