Title: Purification of antibiotic 106í¬7
Filed: 1954-10-08
Abstract: Antibiotic 106-7 is purified from aqueous solution at alkaline pH by extracting with an aliphatic alcohol containing from one to five carbon atoms in the molecule and recovering the antibiotic from the alcohol extract.  The pH may be 8 to 12 and is preferably 9-10.  pH is adjusted by means of water-soluble inorganic or organic bases such as the alkali metal or alkaline earth metal hydroxides, ammonium hydroxide, aliphatic amines including quaternary amines.  It is preferred to use sodium, potassium or ammonium hydroxides.  Specified alcohols are methanol, ethanol, isopropanol, or mixtures thereof. Antibiotic 106-7 is precipitated from the concentrated alcoholic extract by adjusting the pH to 5.5 to 6.0 by means of an inorganic acid such as hydrochloric or sulphuric or by an organic acid such as a C1-C5 aliphatic carboxylic acid especially acetic or propionic acid, and a sulphonic acid, e.g. p-toluene-sulphonic acid.  It is desirable that the base and acid are so chosen that the salt produced is soluble in the alcohol used in the extraction.  The purification process may be applied to the eluates obtained during the isolation of antibiotic 106-7 by means of ionexchange resins.  Specifications 757,089, 757,090 and 758,496 are referred to.

Abstract: A process of producing a bleached sulphate or sulphonate detergent comprises mixing a water-soluble silicate and a hypochlorite of an alkali metal with an aqueous slurry of a water-soluble salt of an organic sulphuric acid reaction product having detersive properties. The process is particularly applicable to the treatment of alkyl aryl sulphonates, usually those having an alkyl chain of 8 to 22 carbon atoms, e.g. dodecyl-benzene sulphonate, dodecyl-naphthalene sulphonate and tetradecyltoluene sulphonate, to water-soluble salts of the sulphuric acid ester of higher fatty acid glycerides, such as the sodium salt of the sulphuric acid ester of coconut oil fatty acid mono-glycerides, and to sulphuric acid esters of fatty alcohols derived from coconut oil fatty acids or other acids having 8 to 22 carbon atoms.  Sodium, potassium and lithium hypochlorites are specified.  Sodium silicate is the preferred silicate, those with a Na2O:SiO2 ratio between 1:2 and 1:3.25 being particularly advantageous.  The hypochlorite may be used in amount between 0.1 and 5 per cent, and the silicate from about 1 per cent upwards, based on the weight of the water-soluble salt. The components may be mixed in any order, but preferably the hypochlorite is added last.  The bleaching may be effected batchwise or continuously.  Table I shows the reduction in colour of portions of dodecyl benzene sulphonate (obtained by polymerizing propylene, condensing the tetramer with benzene, sulphonating and neutralizing) on treatment with sodium hypochlorite alone, sodium silicate alone, and sodium hypochlorite and sodium silicate together.  Table II shows the reduction in viscosity of a 50 per cent slurry of such a sulphonate when treated with a sodium silicate.ALSO:Bleached sulphate or sulphonate detergents are produced by mixing a watersoluble silicate and a hypochlorite of an alkali metal with an aqueous slurry of a water-soluble salt of an organic sulphuric acid reaction product having detersive properties.
