Abstract

The invention relates to a process for producing polyacrylate particles by way of suspension polymerization and subsequent agglomeration. It was based on the problem of specifying a process for producing polyacrylate particles having defined shape and size, which enables improved heat management and requires a minimum amount of organic substances. Mechanical operating steps for establishing the shape and size of the particles ? especially grinding and sieving ? are to be avoided in order to produce a minimum amount of undersize. Finally, it is to be possible to implement the process economically on an industrial scale. An essential aspect of the process of the invention is that the steps of polymerization and agglomeration are conducted in separate apparatuses, namely suspension polymerization in a continuously operated capillary reactor and agglomeration in a batchwise reactor. The use of microstructured apparatuses is a further significant aspect of the invention.

Abstract

The present invention is concerned with methods that reduce the population of microorganisms present during the malting processing of grain and seeds. More specifically, microorganism levels are reduced in grain and seeds being malted by contacting the grain or seeds with a sanitizing solution that contains a peroxyacid and hydrogen peroxide. This is done shortly before steeping, the first step in malting procedures. Optionally, a sanitizing solution containing a peroxyacid and hydrogen peroxide may also be used at other points in the malting process, preferably during steeping.

Abstract

The present invention relates to a process for electrochemical preparation of an alkali metal alkoxide solution. The process is performed in an electrolysis cell having three chambers, wherein the middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to cations, for example NaSICON, and from the anode chamber by a diffusion barrier, for example a membrane selective for cations or anions. The process according to the invention solves the problem that a concentration gradient forms in the middle chamber of the electrolysis cell during the electrolysis, which leads to locally lowered pH values and hence to damage to the solid-state electrolyte used. This is prevented in that a gas is introduced into the middle chamber during the electrolysis, which results in better mixing of the electrolyte solution in the middle chamber and hence prevents the formation of a concentration gradient.

A method for preparing 1,2-propanediol by the steps of (a) continuously reacting propene with hydrogen peroxide in the presence of a catalyst mixture comprising a quaternary ammonium salt and a polytungstophosphate in a liquid reaction mixture comprising an aqueous phase with a maximum apparent pH of 6 and an organic phase comprising an alkylaromatic hydrocarbon solvent, (b) withdrawing liquid reaction mixture from step a) and adding a water-soluble sulfate salt or sulfuric acid to provide a mixture comprising from 500 to 10,000 mg/kg of sulfate ions in the aqueous phase, (c) separating the mixture obtained in step b) into an aqueous phase (Pa) comprising 1,2-propanediol and an organic phase (Po), (d) recycling at least a part of the organic phase (Po) to the reaction step a) and (e) recovering 1,2-propanediol from the aqueous phase (Pa) allows extended operation of the reaction with little loss of tungsten and phase transfer catalyst.

Abstract

The method for preparing 1,2-propanediol comprises step a) of reacting propene with hydrogen peroxide in the presence of a catalyst mixture comprising a phase transfer catalyst and a heteropolytungstate in a liquid reaction mixture comprising an aqueous phase with a maximum apparent pH of 6 and an organic phase; step b) of separating the reaction mixture into an aqueous phase (Pa) comprising 1,2-propanediol and an organic phase (Po); step c) of recycling at least part of the separated organic phase (Po) to the reaction step a); and step d) of recovering 1,2-propanediol from the separated aqueous phase (Pa); wherein in step d) 1,2-propanediol is separated from the aqueous phase (Pa) by distillation and the apparent pH of the separated aqueous phase (Pa) is adjusted to at least 9 prior to the distillation to reduce the content of formic acid and acetic acid in the recovered 1,2-propanediol.

Abstract

The process for preparing 1,2-propanediol comprises a step of dehydrogenating propane to provide a product stream comprising propane, propene and hydrogen; separation steps separating the product stream into a stream consisting essentially of hydrogen, a stream enriched in propane and a stream enriched in propene; a step of reacting the stream consisting essentially of hydrogen with oxygen to provide a stream comprising hydrogen peroxide; a step of reacting the stream enriched in propene with the stream comprising hydrogen peroxide in the presence of a catalyst mixture comprising a phase transfer catalyst and a heteropolytungstate in a reaction mixture with two liquid phases; and steps of separating the reaction mixture of the propene oxidation into an aqueous phase and an organic phase, recycling the organic phase to the propene oxidation and separating 1,2-propanediol from the aqueous phase.
