Impregnation of 12-tungstophosphoric acid on tonsil: An effective catalyst for esterification of formic acid with n-butyl alcohol and kinetic modeling
Altıokka, Mehmet Riza; Akbay, Elif Ödeş; Him, Zeynep (Elsevier Science BV, 2014)Esterification of formic acid with n-butanol was catalyzed by dodecatungstophosphoric acid, H-3 PW12O40 (DTP) impregnated on tonsil earth. A series of catalysts containing 10%, 20% and 30% of DTP on tonsil earth were ... -
Investigation of the dissolution kinetics of kaolin in HCl solution
Altıokka, Mehmet Riza; Hoşgün, Halit Levent (Elsevier Science BV, 2003)Kaolin with a given size distribution was calcined at 1023 K for 2 h. The calcined samples were digested in hydrochloric acid solutions of known concentration at constant temperatures. The samples taken from the solution ... -
Investigation of the Dissolution Kinetics of Meta-Kaolin in H2SO4 Solution
Altıokka, Mehmet Riza; Akalın, Handan; Melek, Nergis; Akyalçın, Sema (American Chemical Society, 2010)Kaolin with a given size distribution was calcined at 1023 K for 2 h then digested in 3 0, 4 5, and 60 N sulfuric acid at constant temperatures within the range 328-358 K The samples taken from the solution at predetermined ... -
Kinetics of hydrolysis of benzaldehyde dimethyl acetal over Amberlite IR-120
Altıokka, Mehmet Riza; Hoşgün, Halit Levent (American Chemical Society, 2007)The kinetics of the hydrolysis of benzaldehyde dimethyl acetal has been studied using a circulated batch reactor in dioxane. Amberlite IR-120, in its acidic form, was used as a heterogeneous catalyst. Kinetic expression ... -
Kinetics of the Hydration of Ethylene Oxide in the Presence of Heterogeneous Catalyst
Altıokka, Mehmet Riza; Akyalçın, Sema (American Chemical Society, 2009)Kinetic data on the hydration of ethylene oxide was obtained from both uncatalyzed and heterogeneously catalyzed reactions using a pressurized batch reactor. Amberjet 4200/HCO(3)(-) was used as the heterogeneous catalyst, ... -
Kinetics study of esterification of acetic acid with isobutanol in the presence of amberlite catalyst
Altıokka, Mehmet Riza; Çıtak, A (Elsevier Science BV, 2003)Kinetic data on the esterification of acetic acid with isobutanol have been obtained from both the uncatalyzed and heterogeneously catalyzed reactions using a stirred batch reactor in dioxane. The equilibrium constant, ... -
Power-Consumption for a Scraped-Surface Heat-Exchanger With a No-Leak Reactor
Altıokka, Mehmet Riza (American Chemical Society, 1992)In this work, the power consumption for a scraped-surface heat exchanger with a "no-leak" reactor was investigated to scale up a pilot plant reactor for industrial use. The experimental results Obtained at various speeds ... -
Reaction kinetics of the catalytic esterification of acrylic acid with propylene glycol
Altıokka, Mehmet Riza; Ödeş, Elif (Elsevier Science BV, 2009)The kinetics of esterification of acrylic acid with propylene glycol has been studied in the presence of Amberlyst-15 as a heterogeneous catalyst. The reaction was realized in a batch reactor at different temperatures and ... -
Some physical effects of reaction rate on PbS thin films obtained by chemical bath deposition
Altıokka, Barış; Baykul, Mevlana Celalettin; Altıokka, Mehmet Riza (Elsevier Science BV, 2013)Thin films of polycrystalline lead sulfide (PbS) have been deposited on glass substrates at 303 +/- 1 K using chemical bath deposition (CBD). The precipitation of PbS on solid surfaces under four different reaction conditions ...
