Abstract: 1,214,928. Cephalosporins. ELI LILLY & CO. 1 March, 1968, No. 10028/68. Heading C2A. The invention comprises aminoalkyl phenylacetamido cephalosporanic acids of Formula I: wherein R is H or C 1 -C 2  alkyl and R<SP>1</SP> is H or acetoxy, an inner salt thereof, stereoisomeric mixtures thereof, or a salt thereof with a pharmaceutically acceptable acid or base. Typical compounds are 7-[4<SP>1</SP>-(aminomethyl) phenylacetamido] cephalosporanic acid and 7-[4<SP>1</SP> (α- aminoethyl) phenylacetamido] desacetoxycephalosporanic acid. The compounds are prepared by acylating 7-aminocephalosporanic acid or 7-aminodesacetoxycephalosporanic acid, or a water-soluble salt thereof, with an acylating acid of formula or a reactive derivative thereof, wherein R is as defined above and the amino group has a conventional protective group, and removing said protective group. The protective group, e.g. carbobenzoxy or tert.-butoxycarbonyl, is removed by (a) hydrogenation in presence of a palladium catalyst, (b) treatment with formic acid at room temperature for 1-5 hours, (c) treatment with trifluoroacetic acid to form the acid salt, followed by treatment with an anion exchange resin in base or acetate form to produce the cephalosporin acid in the Zwitterion form. When the separate optical cephalosporin isomers are desired, the selected 2-[4<SP>1</SP>-(α- aminoalkyl) phenyl] acetic acid starting materials can be resolved in a conventional manner to separate the desired optical d- or l-acid prior to the acylation step. Salts of the cephalosporins may be with bases, e.g. alkali metal or amine salts, or with acids, e.g. hydrochloric or trifluoroacetic acid. The cephalosporins are orally acceptable. A pharmaceutical composition for oral use comprises an aminoalkylphenylacetamido cephalosporanic acid of Formula I and a carrier.

Title: Improvements in the production of alkali nitrate
IPC: C01D9/10
Filed: 1935-04-02
Abstract: In the production of alkali nitrate by reaction between alkali chloride and ammonium nitrate in aqueous solution, the alkali chloride is suspended in a solution saturated with alkali chloride, alkali nitrate, and ammonium chloride, and the ammonium nitrate dissolved in a similarly saturated solution then added. Reaction may be effected at room temperature with stirring, and the reaction mixture be cooled to remove the heat of crystallization.  By this procedure, assisted if desired by suspending a large quantity of coarse-grained alkali nitrate crystals in the reaction liquor, the crystals of alkali nitrate in the mixture of alkali nitrate and ammonium chloride deposited during the reaction are coarse-grained, and render separation of the two salts by mechanical means, such as elutriation, easy.  An example relates to the production of sodium nitrate.
