    摘要: Certain cephalosporins having a heterocyclicthiomethyl group at the 3-position such as cefoperazone are prepared by reacting a solution of a 7-acylamidocephalosporanic acid having a free amino group as part of said acyl substituent with about an equi-molar amount of the thiolester ##STR1## wherein --S-Het is the desired conventional heterocyclicthio group which displaces the 3-acetoxy group of the starting acid and ##STR2## is the conventional acyl group which displaces a hydrogen on the free amino group which is part of the acyl substituent of the starting 7-acylamidocephalosporanic acid.

    摘要: An object of the present invention is to solve problems of conventional ozone-scavenging materials and to provide an ozone-scavenging material capable of effectively decomposing/removing ozone at low cost. To attain the above object, the present invention provides an ozone-scavenging material characterized in that a metal having ozone-decomposing ability or an oxide thereof is supported on an organic polymer base having a polymer side chain having an ion exchange group on the backbone of a polymer. Said ozone-scavenging material can be prepared by introducing a polymer side chain having an ion exchange group onto the backbone of an organic polymer base, bringing the resulting organic polymer material into contact with a salt of a metal having ozone-decomposing ability to support the ion of said metal on the ion exchange group, and then precipitating fine particles of said metal or an oxide of said metal on the organic polymer material by oxidation or reduction.
