Patent GB-645253-A (GB)
Title: Isolation of anhydrous organic compounds from aqueous solutions thereof
IPC: B23F19/02
Filed: 1946-05-01
Abstract: Water-soluble, solid organic compounds are isolated from crude aqueous solutions by mixing the solution with a hydrophobic solvent which is a non-solvent for the organic compound but a solvent for the impurities known to be associated therewith, subjecting the mixture to distillation until all the water has been removed by entrainment with part of the solvent so as to leave a suspension of the organic compound in residual solvent, and separating the organic compound from the suspension.  The process may be carried out on the mother-liquor obtained from an initial crystallization of the aqueous solution.  The hydrophobic solvent is suitably chosen from hydrocarbons such as toluene, chlorinated hydrocarbons such as chloroform, alcohols such as butanol, and ketones such as methyl ethyl ketone.  A mixture of two solvents such as xylene-isoamyl alcohol, may be employed.  In an example, crude (95 per cent) vitamin C is dissolved in water, charcoal is added, the mixture is stirred for 1 hour at 60 DEG  C., and then filtered hot.  The filtrate is charged to a still with an equal volume of toluene; and distilled under 27 inches of vacuum with further additions of toluene, until all the water is removed. The resulting slurry is cooled to 15 DEG C. and filtered.  The filter-cake is washed with isoamyl alcohol, then with ether, and dried.  The product is 99.8 per cent l-ascorbic acid.  In another example, crude sulphosalicylic acid is dissolved in a small quantity of water at 80 DEG  C., and the solution is filtered.  The filtrate is cooled, with agitation, to crystallize sulphosalicylic acid dihydrate which is filtered off, washed with water, and dried at a temperature below 50 DEG  C.  The mother-liquor and washings are distilled with xylene under vacuum until completely dehydrated. Crude sulphosalicylic acid is filtered-off from the resulting suspension, and washed; it may be added to a subsequent batch for final purification.  In a further example, detailed experimental comparison is made between the purification of l-ascorbic acid by the process of the invention using tetrachlorethane and by a conventional process involving crystallization and vacuum evaporation.  The yield is 7 to 10 per cent higher by the azeotropic process.  Two other examples relate to the purification of ascorbic acid using as entrainer methyl ethyl ketone and isobutanol respectively.  Other examples describe the purification aminothiazole and l-sorbose.  Specification 16344/07, [Class 32], is referred to.

Title: Process for producing polyglycidyl compounds
IPC: C07D303/36
Filed: 1978-04-07
Abstract: Polyglycidyl compounds of the formula <IMAGE> in which A is phenylene or cyclohexylene, and R is hydrogen or methyl, are prepared by reacting a corresponding diamine with an epihalohydrin, and subsequently dehydrohalogenating the resultant product. In step (A), the diamine is slowly introduced into the epihalohydrin at a temperature below 60 DEG C in such amounts that the molar ratio between the diamine and the epihalohydrin is from 1:5.5 to 1:15. The addition reaction is carried out at a temperature of from 10 to 60 DEG C. Water is always present in the reaction system. At the time when the addition of the diamine to the epihalohydrin is complete, the water is present in an amount of from 0.5 to 15 mol per mol of the added diamine. In step (B), the water and excess, unreacted epihalohydrin are removed from the system during and/or after addition of the alkali to the reaction product obtained in step (A), and at the same time the dehydrohalogenation of the reaction product is carried out to form the polyglycidyl compound of the formula (I). The resultant compound can be used for the preparation of plastics.
