    Abstract: 2.1. Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at only a few percent. Drying the crude fermentation broth and using it as such generally led to aggregating sticky products or to products having too low a supplementary amino acid content. Using the new animal feed supplement and preparation process, a supplementary amino acid is intended to be made available which is not too expensive, not excessively hygroscopic or sticky, and whose contents can be standardised. 2.2. The animal feed supplement is based on a fermentation broth and contains the majority of its components, if required, with the exception of part of the biomass. Preferably, the biomass is present at no more than 10 % by weight of the dry matter. Proteins are preferably present at up to a maximum of 10 % by weight. For the production, during fermentation, at least towards the end, the sugar content is adjusted to a value of at most 4 g/l and during further processing, if required, at least a part of the biomass is separated off. 2.3. Supplementation or preparation of animal feed agents or premixes, in particular containing lysine.

    Abstract: The invention relates to a process for the fermentative production of amino acids, in which a strain of the genera Brevibacterium or Corynebacterium producing one or more amino acids is cultured in a nutrient medium and, at the end of the fermentation, the amino acid(s) is/are isolated from the culture fluid, which process is characterised in that following the strong growth phase the bacterial culture has less assimilable carbon source available than it could metabolise on account of the strain construction and of the amount of the otherwise necessary supplements provided in the nutrient medium.

    Abstract: Crude nicotinamide is purified by a recrystallization and in this way freed especially from nicotinic acid and salts of nicotinic acid. As solvent there is used a 2-methylpropanol-1 containing water. The recrystallization takes place at a pH between about 7 and 10.

    Abstract: The gaseous mixture resulting from the catalytic reaction of 3-methylpyridine with ammonia and oxygen is treated with water to recover 3-cyanopyridine. The treatment takes place in two steps. In the first step there is used a temperature of about 30 DEG to 60 DEG C. and in the second step at a temperature about 10 DEG to 30 DEG C. lower than in the first step.

    Abstract: The present invention provides a process for producing 2,3:5,6-bis-cycloalkeno)pyridines from cycloalkanones, in which cycloalkanones having at least one reactive methylene group adjacent to the keto group are reacted with aliphatic aldehydes and with ammonia in the gas phase at temperatures from approximately 250 to 550.degree.C in the presence of a catalyst having dehydrating and dehydrogenating properties.

    Abstract: 1397153 Formaldehyde DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 7 Sept 1972 [14 Sept 1971] 41551/72 Heading C2C [Also in Division B1] Formaldehyde is produced by the oxidation of methanol with a free oxygen-containing gas at elevated temperature over a catalyst comprising oxidic compounds of molybdenum and iron in a weight ratio calculated as MoO 3 to Fe 2 O 3 of less than 10 to 1 and having a titanium dioxide content of up to 90% wt, wherein the catalyst has been prepared by a specified method of coprecipitation, shaping and calcining (see Division B1). The oxidation is effected at 275-310‹ C., using a methanol to air molar ratio of from 129 : 1 to 15 : 1 by passage of the gas mixture through a tubular reactor immersed in an oil bath.
