Title: Improvements relating to electrodialysis processes
Inventor: TYE FRANK LAURENCE
IPC: C01B21/42
Filed: 1956-02-20
Abstract: 815,154. Electrodialysis. PERMUTIT CO. Ltd. Feb. 7, 1957 [Feb. 20, 1956], No. 5201/56. Class 41. An electrodialysis process is carried out in a cell divided into compartments by alternate cation-exchange and anion-exchange barriers in which one or more compartments bounded on the cathode side by a cation-exchange barrier and on the anode side by an anion-exchange barrier are filled with fluid permeable packing of a single ion exchange material and an aqueous solution of a salt and a voltage is applied across the cell whereby the ions of the salt that are exchangeable by the ion-exchange material migrate from the filled compartments preferentially to the ions of the salt that have the other sign and the ionic balance is maintained by preferential migration of hydrogen or hydroxyl ions out of the compartments so that an excess of hydroxyl or hydrogen ions respectively remains behind. As shown, a five-compartment cell comprises a cathode compartment 6, compartments 8, 9 and 10 and an anode compartment 7, separated from one another by alternate cation-exchange and anion-exchange membranes designated " C " and " A " respectively. Compartments 8 and 10 are filled with anionexchange material together with an aqueous solution of a salt MX. Compartment 9 contains an ionising solvent. The current in compartments 8 and 10 is largely carried by the anions X moving on the anion-exchange material and hence to maintain the ionic balance in these compartments more hydrogen ions than cations M pass through the membranes C. Thus acid HX is formed in compartment 9 and alkali MOH in compartments 8 and 10. The cation exchange material may be a sulphonated crosslinked polystyrene resin and the anion exchange material may be a chlormethylated and aminated cross-linked polystyrene resin or a basic polystyrene resin containing quaternary ammonium groups. Examples describe the application of the process for reducing the alkalinity of tap water and for converting lithium sulphate to lithium hydroxide. Reference is also made to the production of hydrochloric acid from sodium chloride, nitric acid from sodium nitrate and ammonium hydroxide from ammonium chloride.

Title: Manufacture of 4-aminosalicylic acid salts of heterocyclic carboxylic hydrazides andof their complex copper, gold and iron salts
IPC: C07D213/86
Filed: 1953-02-25
Abstract: The invention comprises 4-aminosalicylic acid salts of heterocyclic carboxylic acid hydrazides and the preparation thereof by reacting 4-aminosalicylic acid, or a salt thereof with an inorganic base, and a heterocyclic carboxylic acid hydrazide, or a salt thereof with an inorganic acid, in an inert liquid medium in which both the reactants are soluble, e.g. alcohol or aqueous alcohol, and allowing the salt to crystallize out.  The invention also includes the complex copper, gold and iron salts of the above salts and the preparation thereof by carrying out the above process in the presence of a salt of copper, gold or iron which is soluble in the liquid medium used.  The preferred heterocyclic carboxylic acid hydrazide is a pyridine carboxylic hydrazide, e.g. pyridine - 4 - carboxylic acid hydrazide. The complex copper, gold or iron salts may be prepared by adding an aqueous solution of the metal salt to an alcoholic solution of the 4-aminosalicylic acid and the heterocyclic carboxylic acid hydrazide. The metal salt used may be an inorganic salt in conjunction with sodium acetate as a buffer salt, or an acetate salt may be used. Suitable metal salts mentioned are copper salts such as a copper sulphate or chloride, an iron salt such as ferrous or ferric sulphate or chloride, or a gold salt such as a gold chloride.  In the examples, complex salts are formed from pyridine-4-carboxylic acid hydrazide and 4-aminosalicylic acid, and from pyridine-4-carboxylic acid hydrazide, 4-aminosalicylic acid and cupric sulphate in the presence of sodium acetate.

Title: Preparation of hop extract emulsions
IPC: C12C3/08
Filed: 1966-02-08
Abstract: A hop extract is solubilized and stabilized by intimately mixing with it a non-toxic emulsifying agent, water and gum arabic.  When sorbitol is additionally included in the mixture less gum arabic need be used; typical proportions of the two constituents are 36%-7% by weight of gum arabic and 0%-45% by weight of sorbitol.  Aqueous solutions of the gum arabic and sorbitol may be employed.  The hop extract is heated to about 70 DEG C. to ensure complete and rapid emulsification. Non-isomerized, pre-isomerized, and reduced pre-isomerized hop extracts are suitable.  The hop extract emulsions produced by the intimate mixing are soluble in cold water, wort and beer. Non-isomerized hop extract emulsions should be added to the wort for isomerization to take place during boiling, whereas pre-isomerized hop extract emulsions may be added at any stage in the brewing e.g. to the fermented beer or ale. The hop extract emulsions may be used to supplement a hopping with hops.  Emulsifying agents: dioctyl sodium sulphosuccinate and sodium lauryl sulphate (preferred); polyoxyethylene sorbitan monolaurate, monopalmitate, monostearate, monooleate and tri-oleate; sorbitan monolaurate, monopalmitate, mono-oleate or tri-oleate; polyethylene glycol; and propylene glycol monolaurate; a proportion of 0.04%-2.0% is usually sufficient. Preferred ranges of proportions for the various constituents of the hop emulsions are disclosed.
