Silver catalysts and their use in producing ethylene oxide. Rebsdat, Siegfried; Mayer, Sigmund; Alfranseder, Josef (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3310685 A1 9 Feb 1984, 30 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: B01J023-50; C07D301-10. APPLICATION: DE 83-3310685 24 Mar 1983. PRIORITY: DE 82-3227753 24 Jul 1982. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 67 Catalysts for the prodn. of ethylene oxide (I) [75-21-8] from O and C2H4 [74-85-1] consist of 8.6-10.6:0.Several substances with their cas registry numbers 563-63-3 and 74-85-1 may be metioned in this study.014-0.026 (wt. %) Ag-Cs on a-Al2O3. The catalysts are prepd. by dissoln. of AgNO3 (or AgOAc) and CsNO3 (or CsOAc) in a 1:2.7-4.4:2.8-4.2 tert-BuNH2 [75-64-9]-sec-BuNH2 [13952-84-6]-H2O soln. and impregnation of the support. Alternatively, the Cs can be impregnated after impregnation of Ag. The catalysts have a 79-81.3% selectivity to I at 183-197° with 6-12% C2H4 conversion. .

Preventing fruit decay. Nelson, Paul M. (FMC Corp. , USA). U.S. US 4434185 A 28 Feb 1984, 4 pp. Cont. 24634-61-5 and 17804-35-2 are cas registry numbers. These chemicals are also mentioned in this article.-in-part of U.S. Ser. No. 166,944, abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A23B007-00; A23B007-10; A23B007-16. NCL: 426308000. APPLICATION: US 81-300080 8 Sep 1981. PRIORITY: US 80-166944 8 Jul 1980; US 80-166945 8 Jul 1980. DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Citrus fruit may be protected against fungal rot by treating them with a combination of a sol. sorbate and at least 1 antifungal agent of the benzimidazole type, an alk. metal o-phenylphenol, or sec- butylamine [13952-84-6]. Thus, oranges showed only 11% spoilage after 7 days storage when they were treated with Na o-phenylphenol [132-27-4] applied from a std. foamer, and then with water contg. 2000 ppm thiabendazole [148-79-8] and 2% K sorbate [24634-61-5] 24 h after inoculation with Penicillium digitatum spores, 50% of which were resistant to thiabendazole and 50% of which were o-phenylphenol-resistant. Control oranges showed 36% spoilage after 7 days. .
