Abstract
The present invention relates to a process and an oxidizing unit for producing hydrogen peroxide in an anthraquinone process. The inventive process and oxidizing unit comprise a compressor for obtaining hot compressed oxygen containing gas. The hot compressed oxygen containing gas is utilized in a heat exchanger to increase the temperature of a compressed (cold) offgas obtained in an oxidizing step for the production hydrogen peroxide. Accordingly, the compressed and heated offgas can subjected to an expander without the formation of droplets or damaging the equipment. Moreover, the process and an oxidizing unit reduce the required amount of energy in the form of electrical power and steam, as well as the required amount of cooling medium in an anthraquinone process.

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 relates in a first aspect to an enzymatic method for the production of an L-glufosinate P-alkyl ester. This method is characterized by a step (c) in which an L-glufosinate P-alkyl ester carbamoylate is reacted to give the corresponding L-glufosinate P-alkyl ester. This step (c) is catalyzed by a carbamoylase, preferably by an L-enantioselective carbamoylase. The L-glufosinate P-alkyl ester carbamoylate employed in step (c) may be obtained by reaction from the corresponding L-glufosinate hydantoin P-alkyl ester. This optional, antecedent step (b) is catalyzed by a hydantoinase, preferably an L-enantioselective hydantoinase. Even more preferred, the L-glufosinate hydantoin P-alkyl ester employed in step (b) may be obtained by reaction from the corresponding D-glufosinate hydantoin P-alkyl ester. This optional, antecedent step (a) is preferably catalyzed by a hydantoin racemase. In a second aspect, the present invention relates to an enzymatic method for enantioselective production of an L-glufosinate P-alkyl ester from a mixture MIIIA of L- and D-glufosinate P-alkyl ester hydantoins. In the method according to the second aspect of the invention, the mixture MIIIA is provided in a step (i-A) and employed in steps (ii) and (iii). Steps (ii) and (iii) correspond to steps (b) and (c) described above, respectively, wherein in step (c), an L-carbamoylase is employed. In an optional, preferred step (i-B) of the method according to the second aspect of the invention, corresponding to preferred step (a) described above, a hydantoin racemase is preferably used to convert at least a part of the D-glufosinate P-alkyl ester hydantoin in the mixture MIIIA into its corresponding L-enantiomer, giving a mixture MIIIB, which is then employed in steps (ii) and (iii). The L-glufosinate P-alkyl ester obtained in the methods according to the first or second aspect of the invention may be saponified to give L-glufosinate.

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.

Abstract
In a method for preparing 1,2-propanediol by the steps of reacting propene with hydrogen peroxide in the presence of a phase transfer catalyst and a heteropolytungstate in a liquid two phase reaction mixture with an organic phase comprising an alkylaromatic hydrocarbon solvent, separating the reaction mixture into an aqueous phase comprising 1,2-propanediol and an organic phase, recycling the oxygen depleted organic phase (Pd) to the reaction step, and recovering 1,2-propanediol from the aqueous phase, the reaction and separation steps are carried out in liquid flooded vessels at a pressure high enough to suppress desorption of gas from the liquid reaction mixture and the separated organic phase is contacted with a stream of a non-flammable gas to desorb from 10 to 75 % of the oxygen dissolved in the organic phase into the stream of non- flammable gas before recycling the organic phase, which purges oxygen safely with little loss of propene.

Abstract
Disclosed are a process of producing a polyurethane foam product, a polyurethane foam product pre-mix, polyurethane foam product formulation, and a polyurethane foam product. The process of producing the polyurethane foam product includes contacting a halogen containing composition with a polyurethane foam product pre-mix. The polyurethane foam product pre-mix includes the halogen containing composition. The polyurethane foam product formulation includes a polyol component, an isocyanate component, and a halogen containing compound component. The polyurethane foam product is formed by the pre-mix having the halogen containing composition.
