Abstract: A bag for preserving and transporting a sterile product in powder form and a method for preparing solutions of the sterile product in the bag. The bag contains a sterile product in powder form and has a port closed by a membrane through which a solvent can be fed into the bag to form a sterile solution of the powder. Further, the bag contains an amount of the sterile product in powder form adapted to give with the solvent and within the bag a reconstituted ready to use solution that only partially fills a capacity of the bag.

A salt of the compound of formula (I) is isolated from the reaction mixture, after washing with acidic water and addition of a pharmaceutically acceptable acid, by treatment with a suitable solvent.

Abstract: Cephalosporine desacetoxy esters having the formula ##STR1## wherein R is selected from the group consisting of ##STR2## and R.sub.1 is selected from the group consisting of ##STR3## Such esters and salts thereof having antibiotic activity are prepared by reacting 7-ADCA with bromophthalide or chloromethyl pivalate in the presence of an alkylamine at a temperature in the range of 0.degree.-70.degree. C. The reaction product is reacted with chloride chlorohydrate of D(-)dihydrophenylglycine or D(-)p-hydroxy phenylgycine.A salt of the compound of formula (I) is isolated from the reaction mixture, which after washing with acidic water and addition of a pharmaceutically acceptable acid is obtained by treatment with suitable solvent.

Abstract: N-carboxy cefadroxil disodium salt having formula ##STR1## Said salt is endowed with antibiotic activity and can be administered parenterally.

Abstract: Salts of cefadroxil with an amino acid selected from the group consisting of L-lysine, L-arginine and acetylcysteine. Said salts are obtained by reacting an aqueous suspension of cefadroxil with an aqueous solution of an amino acid or its derivative, selected from the group consisting of L-lysine, L-arginine and acetylcysteine. To isolate the salt, the aqueous solution is submitted to lyophilization.

Abstract: Process for the production of 6-D-.alpha.-amino-p-hydroxyphenylacetamido penicillanic acid which is a potent antibiotic also known generically as amoxicillin. According to the process there is reacted a boron derivative of 6-APA with an acylating agent derived from the D(-)-p-hydroxyphenylglycine, in dimethylformamide or in dimethylsulfoxide in admixture with methylene chloride or chloroform, hydrolyzing and then removing the enaminic group.

Abstract: Process for preparing cephalexine monohydrate and cephadroxyl monohydrate, according to which a reaction is carried out of a mixed anhydride prepared from a Dane salt of phenylglycine or p-hydroxyphenyl-glycine with a chloroformiate, with an aqueous solution of 7-ADCA in a solvent selected from the group comprising dimethyl sulphoxide, dimethylacetamide, formamide, dimethylformamide and dioxane.

Abstract: A process for preparing cephalosporines in which a cephalosporanic derivative is treated with a polar solvent, then with an organic base to give a mixture which is cooled at a temperature lower than -25.degree. C. A cyclic derivative of boron is added to the mixture and the temperature is increased to about 0.degree. C. An intermediate compound is formed which by treatment first with an acylating agent and then with a mixture of water and alcohol provides a solution containing cephalosporines.
