Two model systems have been examined: (i) the catalytic decomposition of aqueous sodium hypochlorite by cobalt peroxide, with oxygen production; (ii) the reaction of alkali metals with alcohols. For case (i) the catalyst was embedded, in the form of a mixture with 90% of zeolite 13X, into the photografted polymer matrix; while for case (ii) the alkali metal reagent, supported onto 90% of zeolite 13X, was incorporated into the microporous membrane. Kinetics of reaction (i) were studied in standard conditions (1.0 <em>M</em> NaOCl; 1.0 <em>M</em> NaCl; 0.25 <em>M</em> NaOH) between 288.2 to 318.2 K, and the relation between pseudp-first order kinetic constants and amount of catalyst incorporated into the membrane determined. Isotope effects for reaction (ii), relative to H<sub>2</sub>, D<sub>2</sub>, HD production, were measured with mixtures of deuterated and non-deuterated CH<sub>3</sub>OH(D), C<sub>2</sub>H<sub>5</sub>OH(D), n-C<sub>3</sub>H<sub>7</sub>OH(D), and i-C<sub>3</sub>H<sub>7</sub>OH(D) at 25 °C, as a function of volume percent of non-deuterated alkanols in the liquid phase.</p><p>For reaction (i) reactivity was found to be substantially the same in the membrane reactor as in ordinary chemical conditions: loss of catalytic activity did not exceed 15%. For reaction (ii) isotope effects, the origin of which is discussed, fully coincided with those measured in the absence of the polymer matrix.</p></div>","PeriodicalId":101060,"journal":{"name":"Reactive Polymers, Ion Exchangers, Sorbents","volume":"9 1","pages":"Pages 11-18"},"PeriodicalIF":0.0,"publicationDate":"1988-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-6989(88)90045-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77013090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
