The invention relates to a device (1), for feeding reactants into a reaction chamber (2), whereby at least one of the reactants is a hot gas stream and at least one other of the reactants is a liquid for vaporisation therein.

Reduces the possibility of errors such as the loss of information (paper).

The invention relates to a method for oxidising an educt using an oxidant in order to obtain a product.

The invention relates to a method for mixing educt streams (1, 2; 5) in order to produce a product stream (10), using a mixer configuration (15, 16) that is provided with a number of educt feeding sites.

The invention relates to a method for isomerizing educt allyl alcohols into product allyl alcohols in the presence of a catalyst.

The educt for dispersion in a chemical manner can, for example, be in the form of calcium oxide or an aluminium alcoholate.

According to said method the educt is used in solid form and/or the reaction is carried out in the presence of a plurality of fluidised bed bodies.

By using 5-azido-laevulinic acid as an educt for the synthesis of 5-aminolaevulinic acid hydrochloride, it is possible to produce this compound with favorable yields and with pharmaceutical quality.

T1 is a temperature between 170°C and the boiling point of the first educt, but not greater than 250°C, and T2 is a temperature between 170 and 250°C.

The direct saponification of methionine nitrile obtained from methylmercaptopropionaldehyde, prussic acid and ammonia gives low yields, catalyst and educt losses and unwanted side-products.

The invention relates to a method for producing 6-alkoxy-(6H)-dibenz[c,e][1,2]-oxaphosphorines, whereby 6H-dibenz[c,e][1,2]-oxaphosphorine-6-oxides of formula (I) are used as an educt.

The inventive method is characterized in that educt allyl alcohol is rearranged in a semicontinuous or continuous operation whereby forming product allyl alcohol inside a suitable reactor containing a catalyst.

Water and a first reactant are supplied to the container, are mixed together to form a reaction liquid, which is conveyed via a line 13 by a pump 15 into the liquid zone 16a of a membrane unit 16.

According to the invention, the anode and/or cathode gas escaping from the fuel cell and/or an educt gas present in the fuel cell system circulates in the heat exchanger for the dissipation of the thermal energy.

Further, every actuality of matter is educed from the potentiality of that matter; for since matter is in potentiality to act, any act pre-exists in matter potentially.
