All rights reserved.Potassium methoxide is the catalyst for methanol carbonylation process with the CO. This catalyst is prepared by reacting potassium hydroxide with methanol at a temperature of 25-50 °C. Besides the reaction temperature, preparation of catalyst was influenced by the composition of the feed of reactants. Chemical composition in the liquid phase were analyzed using gas chromatography method, and composition of vapour phase was predicted using UNIFAC model. Concentration of CH3OK in the catalyst solution increases with increasing molar ratio of feed and temperature. Yield of CH3OK decrease if molar ratio of feed increased. The highest concentration of CH3OK achieved at molar ratio of feed 0.039 and temperature 50°C. Reaction rate for alcoholysis of potassium hydroxide is a function of the concentration of potassium hydroxide. The activation energy was found 17.81 kJ/mole, and pre-exponential factor was 26.3 min-1.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Alcoholysis,Chemical and vapour-liquid phase equilibrium,Kinetics,Potassium methoxide[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
