Abstract: The invention comprises thiophosphoric esters of the formula (CH3O)2P(X)SCH2CH2 SCH(CH3)CONHCH3 wherein X is an oxygen atom or a sulphur atom. They may be obtained (a) by reacting a halogeno phosphate of the formula (CH3O)2P(X1)Hal with a compound of the formula HX2.CH2.CH2.S.CH(CH3) CONHCH3 or with a salt thereof, where X1 and X2 are both sulphur atoms or one of X1 and X2 is an oxygen atom and the other is a sulphur atom and Hal is a halogen atom preferably chlorine, (b) by reacting a salt, e.g. an alkali metal or ammonium salt, of an O,O-dimethylthio (or dithio) phosphoric acid with a reactive ester of the formula Y.CH2. CH2.SCH(CH3)CONHCH3 where Y is the acid residue of a reactive ester, e.g. a halogen atom, or a sulphuric or sulphonic ester group, or (c) by reacting a reactive ester (e.g. a halide) of an O,O-dimethylthio(or dithio)phosphoryl-2-ethanol with the compound HS.CH(CH3) CONHCH3 or with a salt thereof. Method (a) is preferably carried out in a solvent medium at below 150 DEG C. in the presence of a basic condensing agent, e.g. an alkali metal or its hydroxide or carbonate. The reaction may be effected without the condensing agent when the second mentioned reactant is used in the form of an alkali metal salt. Suitable solvents are aliphatic alcohols and ketones and chlorinated hydrocarbons. Methods (b) and (c) are preferably carried out in water or an organic solvent, e.g. an aliphatic alcohol or nitrile, or a ketone, at between 15 and 150 DEG C., e.g. at the boiling point of the solvent used. Examples are given for the production of the O,O-dimethylthiolo(and dithio)phosphoryl compounds using method (a). The products have pesticidal properties (see Group VI).ALSO:A pesticidal composition comprises at least one phosphorus ester of the formula <FORM:0924821/VI/1> wherein X is an oxygen atom or a sulphur atom (see Group IV (b)) together with at least one diluent compatible therewith. Specified diluents include talc, calcined magnesia, kieselguhr, tricalcium phosphate, powdered cork, absorbent carbon black, kaolin, bentonite, aromatic hydrocarbons e.g. toluene or xylene, and mineral, animal or vegetable oils.

Title: Recovery of cephalosporin c
IPC: B01J47/00
Filed: 1961-01-24
Abstract: Cephalosporin C is recovered from a clarified beer containing it and co-present Cephalosporin N by lowering the pH of the clarified beer preferably adjusted to pH5-6 with acetic acid or sodium hydroxide by treatment with a cation exchange material containing strong acidic groups in hydrogen form to a value of from 2.8 to 4.0, separating the cation exchange material from the acidified medium, then passing the acidified medium through a strong anion exchange material in the form of a salt of a weak monobasic organic acid e.g. acetic acid to remove substantially all chloride and other inorganic anions therefrom and thereafter separating the Cephalosporin C from the percolate. The Cephalosporin C may be separated from the percolate by contacting it with an anion exchange material in the form of a salt of a weak monobasic organic acid e.g. acetic acid to adsorb the Cephalosporin C thereon and eluting the adsorbed Cephalosporin C therefrom with acetic or formic acid which, in the case where the anion exchange material is a weak anion exchange material is buffered by the addition of a weak base which is volatile enough to be removed by distillation in vacuo from aqueous solution at a temperature below the decomposition temperature of Cephalosporin C e.g. pyridine or ammonia. The Cephalosporin C may be precipitated from the eluate by acetone, dissolved in water and converted to its sodium salt by treatment with sodium hydroxide or a strong cation exchange resin in sodium form. The removal of chloride and other anions may be effected by a plurality of sections of strong anion exchange material. The Cephalosporin C may be separated from the percolate by adsorption on alumina or charcoal and elution therefrom. Specification 810,196 is referred to.
