Patent GB-814574-A (GB)
Title: Method of producing ascorbic acid
IPC: A61K31/375
Filed: 1957-05-01
Abstract: The invention comprises a method of obtaining pure ascorbic acid by extraction with a twophase system, in starting from natural materials containing ascorbic acid, characterized in that leaves from a plant of the type Tucca Guatemalensis or Fourcroya Gigantea are subjected to grinding in a screw press, after said leaves have been cut up in fragments transversely to the direction of the fibres, then the resulting ground product is pressed in a hammer grinder; the juice obtained is subsequently treated for extraction of the ascorbic acid by way of a solvent system comprising two non-miscible phases, each formed by water, acetone and magnesium chloride; the extract is concentrated and purified by a treatment with acetic acid, lastly pure ascorbic acid is recovered from said extract.  In order to preserve the extracted juice, sodium hydrosulphite and xylol may be added in the preferred proportions of 7 g./l. of the former and 4 ccs./1. of the latter.  The two phases obtained by extraction are opposed in counter-current apparatus, and after concentration the ascorbic acid is crystallized from the upper phase.  Preferably the extraction is carried out in the temperature range 35-40 DEG  C. Alternatively, instead of crystallizing immediately ascorbic acid, subsequent to the step of extraction with water-acetone-magnesium chloride system, the phase containing the extracted ascorbic acid is subjected to a concentration bringing the acetone content to 50/55 per cent with respect to the water present and the phase so concentrated is then subjected to a new extraction with a two system comprising water, acetone and zinc sulphate.  The acetone which forms the lower phase extracts the ascorbic acid.

Title: Process of and Apparatus for Separating Solids from Liquids.
Inventor: SHARPLES PHILIP TRIEST
IPC: C10G73/06
Filed: 1917-09-27
Abstract: 119,288. Sharples, P. T. Sept. 27, 1917. Density separators.-A composition having constituents of different specific gravities is mixed with a carrier liquid heavier than at least one of the said constituents and subjected to centrifugal action to separate the constituents. In a particular example, the lighter constituent is first separated from the remainder of the mixture, which may be further subjected to centrifugal action to separate the carrier liquid, which is heavier than either constituent, from the heavier constituent. The carrier liquid may be returned to the apparatus and used repeatedly. Fig. 1 shows an apparatus for the process described. The composition is introduced 'by a pipe 4 and the carrier liquid by a pipe 6 to the 'bowl 2, in which separation takes place by the centrifugal force as the mixture rises. The carrier liquid and the solid matter pass outside the disk 10 and sleeve 11 to the chamber 11' and the lighter liquid passes through the sleeve 11 to the outlet 14 and thence to the outflow channel 16. The carrier liquid passes to the outlet 12 and flows back to the inlet 6. Solids are discharged by the outlet 18 to the shoot 20.

Title: Process for the partial separation of gaseous mixtures

Filed: 1932-05-19
Abstract: 386,205. Separating gases by liquefaction. FRANKL, M., 234, Ulmerstras'se, Augsburg, Germany. May 19, 1932, No. 14276. Convention date, May 20, 1931. [Class 8 (ii).] A process for the partial separation of gas mixtures comprises, as applied to air, a first rectification under pressure in a column bl, giving a liquid mixture rich in oxygen which is transferred by a pipe 5 to low-pressure rectifier b<11>, and a residue mainly of nitrogen which is liquefied in a condenser c and used as washing liquid in the rectifier b<11> from which the liquid rich in oxygen collecting at the base is drawn off to the condenser c in which it is vaporized outside the low-pressure column. Alternatively, the two bodies of liquid may be transferred from their columns direct to the condenser. The nitrogen from the top of the column b<11> passes off through regenerators A<1>, All alternately, these regenerators cooling incoming compressed air ; while the oxygen mixture and a separate body of air at lower pressure pass alternately through regenerators B<1>, B<11>. Part of the high-pressure air is delivered to a circuit comprising a compressor h, motor k, and exchangers and passes to the low-pressure column. Highpressure air cooled, e.g. by an ammonia refrigerating machine, is liquefied in a coil z and delivered to the column b<1> to compensate cold losses. In a modification, in place of a circuit of compressed air in the motor compressor, nitrogen is withdrawn in gaseous form from the condenser c on the high-pressure side and after passage through this circuit passes away with the nitrogen from the low-pressure column to the exchangers.
