Supportsd Liquid-Phass Catalysts

Halogen-Mediated Oxidative Dehydrogenation of Propane Using Iodine or Molten Lithium Iodide

“…according to the reactions (5)- (10). These reactions produce HI and it has been proposed [5][6][7]36] that HI reacts with Li2O according to Li2O(s) + 2 HI → 2 LiI + H2O (12) We propose that this is a minor reaction since LiI, like many other molten salts, is extremely hygroscopic [12,24,25,27,26] and LiI being "catalysts".…”

“…The use of a molten salt may appear unusual, but there has been quite a bit of work over years exploring the use of molten salts as catalysts [8][9][10][11][12] or as promoters [13][14][15][16][17][18][19][20][21][22][23]. Molten salts have high heat capacity and heat conductivity [24][25][26][27]12] which is helpful in preventing hot spots in oxidation reactions.…”

Carbon Supported Phosphoric Acid Catalysts for Gas-Phase Synthesis of Diesel Additives

“…In general, supported phosphoric acid catalysts can be considered to belong to the family of supported liquid phase catalysts when the reaction temperature is above the melting point of the active phase (H 3 PO 4 : 42 °C) [35]. Historically, phosphoric acid impregnated on kieselguhr or other silica supports-also called solid phosphoric acid (SPA)-was used in solid acid catalysis [36]. SPA is highly active in reactions such as gas-phase oligomerisation of low molecular weight olefins and benzene alkylation to ethylbenzene or cumene.…”

?Ethane oxychlorination? over ?-Al2O3 supported CuCl2?KCl?LaCl3

“…Since the discovery that copper chloride catalyzes the conversion of hydrogen chloride to chlorine in the Deacon process, much work has been done on the oxychlorination reaction of methane and ethylene [1][2][3][4]. However, ethane oxychlorination is promising for developing a rational technology of ethylene chloride production, because ethane as a raw material is cheaper than ethylene [5,6].…”
