Production of mesitylene on an AShNTs-3 catalyst

Production of mesitylene on an AShNTs-3 catalyst. Sultanov, A. S.; Islamova, M. S.Chemicals with cas numbers 108-67-8 and 1318-02-1 also play role.; Sapozhnikova, E. A. (USSR). Deposited Doc., VINITI 1222-74, 4 pp. Avail. BLLD (Russian) 1974. DOCUMENT TYPE: Report CA Section: 25 (Noncondensed Aromatic Compounds) Mesitylene was prepd. in 22.5% yield with no by-products by dehydrating Me2CO at 220.degree. and space velocity 0.6 h-1 in the presence of AShNTs-3 catalysts. The activity of the catalyst was regenerated completely in a stream of air. .

Catalytic conversion of butane to propane

Catalytic conversion of butane to propane. Bernard, Jean R.; Bousquet, Jacques; Grand, Michel (Entreprise de Recherches et d'Activites Petrolieres, Fr.). Ger. Offen. DE 2626840 23 Dec 1976, 18 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C009-08. PRIORITY: FR 75-18911 17 Jun 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Butane [106-97-8] and isobutane [75-28-5] are converted to propane [74-98-6]-rich products by hydrocracking (20-40 bar H pressure) in the presence of mordenite [12173-98-7] catalysts at 325-450.degree.. Thus, a 7-8:1 (vol.) H-butane flow at 400 vol. hourly space velocity was passed over a catalyst (H form) at 330.degree. to provide 41% conversion with selectivity (200 C3/(C1 + C2 + C3)) 198. Isobutane at 310.degree. 1318-02-1 and 12173-98-7 which are cas registry numbers of substances are two of reagents here. was 24% converted with selectivity 199. The use of erionite as a catalyst at 400.degree. gave 23% conversion and 182 selectivity for butane; isobutane was not converted. .
