    摘要: Penicillin is prepared in an industrially advantageous manner by reacting 6-amino-penicillanic acid with silylhalides, to protect the carboxyl group of the 6-aminopenicillanic acid, by forming a mixed acid anhydride grouping, then reacting the above obtained product in the presence of an acid-binding agent with reactive derivatives of carboxylic acid, and then solvolyzing the product to remove the protecting group of the carboxy group to form penicillin.

    摘要: 7-Aminocephalosporanic acids have been prepared in an industrially advantageous manner, by reacting 7aminocephalosporanic acids with a halogenated compound, represented by the formula (III-1) to (III-4), in the presence of an acid-binding agent, to protect the carboxy group of the said 7-acylamidocephalosporanic acid derivatives, by forming a mixed acid anhydride grouping, converting the reaction product into the corresponding imino halide by further reaction with an imino halide-forming reagent, converting the resultant imino halide into the corresponding iminoether, and removing the protecting group of the carboxyl group to form 7-aminocephalosporanic acids.

    摘要: PREPARATION OF TRI-SUBSTITUTED HYDROCARBYL PHOSPHATES, BY REACTING DIHYDROCARBYLCHLOROPHOSPHATES WITH ALCOHOLS IN THE PRESENCE OF CAUSTIC ALKALIS, SUCH AS CAUSTIC SODA AND CAUSTIC POTASH, ETC., WHEREBY THE HYDROEN CHLORIDE FORMED SIMULTANEOUSLY IS NEUTRALIZED QUICKLY WITH THE CAUSTIC ALKALI. ACCORDING TO THIS PROCESS, IT IS POSSIBLE NOT ONLY TO PREVENT THE DECOMPOSITION OF DIHYDROCARBYLCHLOROPHOSPHATES BUT ALSO TO SUPPRESS THE SIDE REACTION REPRESENTED BY THE EQUATION:

    (RO)3PO+HCL-->(RO)2P(O)OH+RIL

    WHEREIN R IS AN ALKYL GROUP. THE COMPOUNDS PRODUCED BY THE INVENTION ARE USEFUL AS ADDITIVES FOR GASOLINE, PLASTICIZERS FOR THERMOPLASTIC RESINS AND FLAME RETARDING AGENTS FOR RIGID POLYURETHANE FOAM, POLYESTER RESIN, ETC.
