Title: Improvements in and relating to the de-polymerisation of cyclic polymers of -e-caprolactam
Inventor: PEACOCK JAMES MACKIE
IPC: C07D201/12
Filed: 1957-02-15
Abstract: Cyclic polymers of e -caprolactam, such as a dimer, are converted into the monomer by contact in the vapour phase with a bed of inert material at elevated temperature (preferably at least 300 DEG  C., e.g. 350-450 DEG  C.), and the resulting vapours treated to recover the monomer.  The preferred pressure is atmospheric.  By "inert material" is meant a material which exerts substantially no chemical or catalytic action, its function being believed to be the rapid transfer of heat to the vaporized polymer; suitable inert materials are sand, silica chips, coke and ceramic materials.  The vaporized polymer may contain monomer or be in the presence of a carrier gas. The monomer may be separated by condensing the vapours and extracting with a suitable solvent, such as water; unreacted polymer may be re-cycled.

Patent GB-803238-A (GB)
Title: An improved process for purifying fermentation or synthetic ethyl alcohol
IPC: B01D3/00
Filed: 1957-02-21
Abstract: Fermentation or synthetic ethanol is purified by mixing the crude alcohol with an alkali metal sulphite, e.g. sodium sulphite, maintaining the sulphite in contact with the alcohol for a period (e.g. 10 hours) sufficient to allow it to react with impurities contained in the alcohol, and then subjecting the mixture to rectification.  Potassium sulphite or lithium sulphite may also be used and, if the pH conditions allow, ammonium sulphite. Controlled pH conditions are suitably maintained, particularly in the case of yeast fermentations; e.g. a mixture of monosodium phosphate and disodium phosphate or a mixture of sulphuric acid and disodium phosphate, is preferably added, for maintaining the pH in the vicinity of the neutral point.  In an example, molasses alcohol of 96 DEG  G.L., having disagreeable taste and smell, is diluted to 70 DEG G.L.; and 10 grm. of pure sodium sulphite, Na2SO37H2O, are added per litre of alcohol. After a contact time of 10 hours between the sulphite and alcohol, the mixture is subjected to rectification.  The carbonyl compounds are collected almost quantitatively in the head fraction.  The middle fraction consists of 96 DEG  G.L. alcohol of neutral smell and taste.
