Patent GB-687160-A (GB)
Title: Manufacture of sulphuric acid
IPC: C01B17/74
Filed: 1950-05-31
Abstract: Sulphuric acid is produced by contacting a gas comprising sulphur trioxide with an aqueous fluid under such conditions that the resulting sulphuric acid reaches a temperature of at least 150 DEG C, the acid then being cooled by contact with air and the air after effecting cooling being contacted <PICT:0687160/III/1> with water or dilute sulphuric acid to effect heat and material exchange.  The resulting heated dilute acid may be employed as the aqueous fluid which is contacted with the sulphur trioxide.  In the Figure, sulphur trioxide enters an adsorber 2 at 1 and is washed with boiling sulphuric acid, the heat-concentrated acid then passing through pipe 3 to an air cooler 4.  Air enters at 5 and after cooling the acid and entraining acid vapours, passes through pipe 6 to a heat and material-exchanger 10 irrigated partly by the acid pumped from the cooler 4 via line 9 and partly by dilute acid added to the system at 11.  The cooled gases, freed from sulphur trioxide and acid vapours, are evacuated at 13 and may be recycled to the cooler 4 to avoid the introduction of water vapour to the cooler.  Product acid is withdrawn at 8.  The aqueous fluid used to absorb the sulphur trioxide may be diluted acid resulting from drying and heating gases with concentrated sulphuric acid, the absorbed water being partly reacted with the sulphuric trioxide and partly evaporated by the heat of the reaction, thereby reconcentrating the acid.  Alternatively, the dilute acid supply may be that from a refrigeration device where water evaporated under low pressure is absorbed in concentrated sulphuric acid.

Title: Metal borohydrides and process for preparing and using same
Inventor: KOLLONITSCH JANOS
IPC: C01B6/00
Filed: 1954-05-12
Abstract: Organic carbonyl compounds, e.g. aldehydes or ketones, are reduced by calcium, strontium or barium borohydride, or solutions thereof in an alcohol, ether or amine.  In Example (6), p-nitrobenzaldehyde is added to a solution of calcium borohydride in ethanol at - 15 DEG  C. with stirring, the mixture is left to stand and the pH adjusted to 5 with 5N HCl, water is added, the mixture is heated, and then cooled, when crystals of p-nitrobenzyl alcohol are formed, which are filtered, and washed with aqueous alcohol. In Example (7), dehydroandrosterone in ethanol is added to a solution of calcium borohydride in ethanol, the mixture is left to stand at - 30 to - 20 DEG  C. and the temperature is then allowed to rise, water is added to the mixture acidified with 5NHCl, the mixture is extracted with chloroform, the extract is washed with water, dried over magnesium sulphate, and concentrated by evaporation to leave a residue of 3b - D 4-17b  androstenediol, which is washed with ether and has a melting point 178-182 DEG  C.  An addition compound of calcium, strontium or barium borohydride with an ether is prepared by reacting an alkali metal borohydride with a halide of calcium, strontium or barium in an anhydrous ether, separating the solution of borohydride from the precipitated alkali metal halide, and evaporating excess ether. In Example (5), sodium borohydride is reacted with anhydrous calcium chloride in tetrahydrofuran with constant stirring in an atmosphere of nitrogen, and excess tetrahydrofuran is evaporated under vacuum.ALSO:Calcium, strontium, or barium borohydrides are prepared by reacting an alkali metal, e.g. sodium or potassium, borohydride with a salt, e.g. chloride or bromide, of calcium, strontium, or barium in a solvent medium from which the borohydride may be isolated.  The solvent may be an anhydrous ether, e.g. tetrahydrofuran, an amine, e.g. isopropylamine or cyclohexylamine, or an alcohol, e.g. glycols, absolute ethanol or methanol.  The reaction is carried out preferably at below 0 DEG  C. and, if effected in tetrahydrofuran, addition compounds of the ether with the borohydride are formed, when excess tetrahydrofuran is evaporated from the solution.  The alkali metal salt, which is precipitated, may be separated, and the borohydride recovered by distilling off the alcohol at below 0 DEG  C. under high vacuum, e.g. - 30 DEG  to - 50 DEG  C.  Alternatively, the alcohol may be distilled from the reaction mixture and the solid residue extracted with a hydroxyl-free selective solvent for the borohydride, e.g. an ether, or amine, as referred to above, or anhydrous liquid ammonia, and the solvent may be evaporated after separation of the alkali metal salt.  The borohydrides, or their solutions, may be used to reduce aldehydes or ketones to alcohols.
