Abstract: The application relates to a process for the preparation of synthesis gases by partial autothermal oxidation of liquid fuels and/or solid fuels in the presence of oxygen or oxygen-containing gases with the addition of a temperature moderator such as steam and/or CO2, in an empty reactor space without baffles at temperatures of 1000 to 1500 DEG C at a pressure of 1 to 100 bar, the reactants fuel and oxygen-containing gas being fed separately to the reactor, characterised in that the steam or CO2 is fed in simultaneously with the feed of the fuel and, immediately before the orifice for the fuel, the steam is let down through one or more nozzles into the fuel stream, the let-down step being carried out with 30 to 250%, preferably 80 to 140%, of the critical pressure ratio. The application furthermore relates to an apparatus for carrying out the process.

Abstract: The invention is concerned with a process for the preparation of a 5-hydroxymethylimidazole of the formula 1 1 where R1 is hydrogen or alkyl of 1 to 18 carbon atoms, phenyl, benzyl or .beta.-phenylethyl, and R2 is alkyl of 1 to 18 carbon atoms or phenyl, wherein an imdazole of the formula 2 2 where R1 and R2 have the meanings given for formula 1, is reacted with formaldehyde or an oligomer of formaldehyde is aqueous hydrochloric acid solution, containing from 5 to 18% by weight of hydrogen chloride, at from 80.degree. to 160.degree.C, if appropriate in a closed system under pressure, the resulting 5hydroxymethylimidazole is isolated in the form of its hydrochloride and the ratio of imidazole to hydrogen chloride being from 1:1.5 to 1:5. The process according to the present invention is particularly usable to prepare 5-hydroxymethylimidazoles in a very simple manner, and in a form free from by-products, on an industrial scale.

Abstract: : The present invention relates to l-hydroxy-methylimidazoles which are unsubstituted or alkyl-substituted in the 2-position and which correspond to the following general formula (I) : wherein R is hydrogen or alkyl of 1 to 18 carbon atoms. This invention is also directed to the manufacture of these new compounds as well as their use as chemical intermediates, e.g. for other imidazole derivatives or for the drug cimetidine.
