Title: Process for the preparation of hydroxyaldehydes and derivatives thereof
IPC: C07C45/75
Filed: 1964-05-06
Abstract: A b -hydroxy-aldehyde is prepared by reacting, under anhydrous conditions, formaldehyde in a polymeric form with an aliphatic aldehyde having at least one hydrogen atom attached to the a -carbon atom in the presence of an alkaline catalyst.  The preferred catalysts are the alcoholates, carbonates, bicarbonates or organic salts of alkali or alkaline earth metals, a mono-, di- or tri-substituted aliphatic amine or an aromatic or quaternary ammonium base.  The process is particularly applicable to the reaction between trioxymethylene and iso-butyraldehyde to give hydroxypivalic aldehyde along with some 2,2-dimethylpropane-1,3-diol and its monoisobutyric and mono-hydroxypivalic esters as by-products.  The hydroxyaldehydes may be oxidized to the corresponding hydroxy acids, for example, using oxygen and an oxidation catalyst such as Ag/Cu in basic solution.  Glycols may also be made by hydrogenation of the hydroxy aldehydes.  Examples are given of (a) the reaction between paraformaldehyde and isobutyraldehyde to give hydroxypivalic aldehyde which is catalytically hydrogenated to give neopentyl glycol; (b) the reaction between paraformaldehyde and iso valerylaldehyde to give 2-isopropyl-hydracrylic aldehyde and (c) the reaction between paraformaldehyde and 2-methylbutyric aldehyde to give 2-methyl-2-ethyl - 3 - hydroxypropionic aldehyde.

Title: A process for the reduction of oxidic ores
IPC: C21B13/08
Filed: 1953-07-09
Abstract: In a process for reducing oxidic ores in the presence of carbonaceous material, the principal part of the reduction is effected in a rotary furnace and the mixture of partly-reduced ore and excess carbonaceous material is directly transferred to an externally heated retort for further reduction.  Approximately 70 per cent reduction is preferably obtained in the rotary furnace and the amount of excess carbonaceous material transferred is approximately 20 per cent of the weight of the ore.  In the example described, oxidic iron ore (with 35 per cent Fe) and coke was fed into a rotary furnace and reduced in counter-current to the furnace gases at a temperature of 1000 DEG  C. so that 65 per cent reduction of the ore was obtained.  The partially reduced ore and excess coke, which amounted to 25 per cent of the weight of the ore, was then transferred to a retort heated by oil burners where after 1 hour, 95 per cent reduction was obtained.  The charge was then cooled and removed on a belt.  The exhaust gases from the retort may be burnt in the rotary furnace.
