23 Ιαν 2023 · Grignard reagents react with carbon dioxide in two stages. In the first, you get an addition of the Grignard reagent to the carbon dioxide. Dry carbon dioxide is bubbled through a solution of the Grignard reagent in ethoxyethane, made as described above. For example:
CO2 + Mg(OH)2 = Mg2(CO3)(OH)2 + H2O is a Double Displacement (Metathesis) reaction where one mole of Carbon Dioxide [CO 2] and two moles of Magnesium Hydroxide [Mg(OH) 2] react to form one mole of Pokrovskite [Mg 2 (CO 3)(OH) 2] and one mole of Water [H 2 O]
Process: split the reaction into two half-reactions, balance the atoms and charges in each half-reaction, and then combine the half-reactions, ensuring that electrons are balanced. Example: Cu + HNO 3 = Cu(NO 3 ) 2 + NO 2 + H 2 O

30 Μαρ 2022 · Understanding the mechanisms of these reactions is accomplished by calculating adsorption energy, charge transfer, electron localization function, and adsorption/dissociation energy barriers of H 2 O and CO 2 upon reactions with the MgO and Mg(OH) 2 clusters.
The reaction of CO with Cl 2 gives phosgene (COCl 2), a nerve gas that was used in World War I. Use the mechanism shown here to complete the following exercises: $$Cl_2\;(g)\rightarrow 2Cl\;(g)\quad \text{(fast)}$$ $$CO\;(g)+Cl\;(g)\rightarrow COCl (g)\quad \text{(slow}) $$ $$COCl\;(g)+Cl\;(g)\rightarrow COCl_2\, (g)\quad \text{(fast})$$
Its basic principle is that Mg(OH)2, as decarbonization agent, absorbs carbon dioxide and converts it into magnesium bicarbonate solution, which is heated in the desorption tower to regenerate magnesium hydroxide over and over again.
