摘要： In a process for manufacturing gas-tight aluminium tubes suitable for carrying out catalytic high-temperature reactions, powdered aluminium oxide is mixed with water, a binder and a plasticizer, and the mixture is deformed by drawing a hank into a cylindrical green body, which is then deformed in at least two places so that the circular cross-section of the tube becomes approximately ellipsoidal. The deformed green body is dried and sintered at 1740°C. Excellent mixing of the gas in the tube is achieved as a result of the constrictions in the cross-section.

摘要： In order to increase active oxygen stability, sodium percarbonate is coated with single or multiple layers of various substances. Sodium percarbonate particles coated according to the invention consist of a core of sodium percarbonate fluidised bed spray granulate and sodium sulphate, which may be partially hydrated, as the sole constituent of a single coating layer. The particles according to the invention exhibit both elevated active oxygen stability and very good ensilability. The coating layer is applied by spraying an aqueous Na2SO4 solution onto the particles to be coated, which were themselves produced by fluidised bed spray granulation, in a fluidised bed and vaporising water at a fluidised bed temperature of 35 to 100 DEG C.

摘要： A process is disclosed for reducing amino acids and derivatives thereof. Compounds of formula (I), in which n = 0 or 1 and R , R , R , R , R and R have the meanings given in the description, are reduced to the corresponding amino alcohols of formula (II): the formula (I) compounds are converted in a first step, in at least one alcohol and with the addition of acid and heat, to an ester, this process producing a reaction mixture containing the ester; the ester is converted in a second reaction step with alkali or alkaline earth borohydride to compounds of formula II. By specifying that the second step be carried out without isolating the ester from the reaction mixture and by using alkali or alkaline earth borohydrides which are not activated, the invention facilitates the production from amino acids and their derivatives of the corresponding alcohols in a simple "single vessel" process, with high yields and in such a way as to preserve a given centre of chirality. Applications: synthesis components, preparation of optically active compounds, splitting of racemic compounds.

摘要： Process for producing ammonium-2-hydroxy-4-(methylthio)-butyrate, mixtures containing the same in liquid form and their use. Processes are known for producing ammonium-2-hydroxy-4-methylthio-n-butyrate (MHHAS) by treating 2-hydroxy-4-methylthio-butyric acid (MHA) with ammonia or by isolating MHA, which also contains dimers and higher oligomers, from a reaction mixture obtained by adding hydrogen cyanide (HCN) to methylmercaptopropionic aldehyde (MMP) and by hydrolysing in mineral acid conditions the thus obtained methylmercaptopropionic aldehyde cyanhydrine (MMP-CH). In order to produce ammonium-2-hydroxy-4-methylthio-n-butyrate and mixtures containing the same with a remarkable fluidity and a very low oligomer proportion by a process based on exclusively "liquid" steps, the reaction mixture is treated with a water-immiscible or partially water-miscible inert solvent, until a first organic extract and a first aqueous raffinate are obtained, and the first organic extract is decomposed into a second organic extract and a second aqueous raffinate by treating it with ammonia and phase separation. Re-extraction of MHA as MHAAS is carried out in the second aqueous raffinate, causing salt formation, and MHAAS is isolated from the second aqueous raffinate. This compound is useful as feedstuff supplement and as methionine substitute.

摘要： The invention relates to a process for improving the storage stability of sodium percarbonate (2Na2CO3.3H2O2) by encasing it in sodium perborate. According to the invention, sodium percarbonate wet salt, obtained by the reaction of soda with hydrogen peroxide in the aqueous phase and separating the salt from the aqueous phase, is treated with a sodium perborate-containing solution or suspension in a solid-liquid separation device according to a process of displacement wash. The invention provides longer storage stability with a thinner perborate coating than prior art processes.
