Fabrication of zeolite-supported cobalt ferrite (CoFe2O4/ H-zsm-5) catalyst for the synthesis of 4-(9-(4-substituted)-1,2,3,4,5,6,7,8-octahydro-3,3,6,6-tetramethyl-1,8-dioxoacridin-10(9H)-yl)benzoic acid derivatives in semi aqueous condition

A cobalt ferrite (CoFe₂O₄/H-ZSM-5) catalyst supported by zeolite has been studied as a multicomponent reaction for making dioxoacridin-10(9H)-ylbenzoic acid derivatives in semi-aqueous conditions. This reaction offers a cost-effective and simple operational strategy and provides different substrates. Scope and various functional groups are well tolerated under optimized reaction conditions. Firstly, the catalyst was characterized using FT-IR, XRD, BET, XPS, TGA, and SEM techniques. The study determined the optimal operating conditions for achieving an efficient synthesis of target organic compounds. The optimized conditions for the synthesis of model compounds (4a) with a yield of 96 % were achieved through a reaction time of 40 min, a catalyst amount of 10 mol%, a temperature of 90 °C, and a solvent of 6/4 of the ethanol and water mixture. All of the characterization measurements confirmed that the catalyst's stability remained unaltered even after four consecutive cycles of the synthesis of model compounds. Furthermore, the reusability feature cuts costs and lessens environmental effects, making it an appealing option for practical applications. The findings emphasize this approach's enormous potential for sustainable chemical synthesis, opening the path for future advances in the sector. In addition, an experiment was set up to look into the thermodynamic and kinetic properties of compound (4a) when it was heated to between 343.15 and 373.15 K with the help of a catalyst. The current investigation has shown that the reaction favors thermodynamics rather than kinetic control.
