Title:OptimizationoftheSynthesisConditionsforortho-Chlorobenzaldehyde
Abstract:
Ortho-chlorobenzaldehyde(o-CBA)isanindustriallysignificantorganiccompoundwidelyemployedinthesynthesisofpharmaceuticals,agrochemicals,anddyes.Thispaperaimstooptimizethesynthesisconditionsforo-CBAusingvariousapproaches,includingtemperature,reactiontime,catalystconcentration,andmolarratioofreactants.Theoptimizationprocessinvolvesconsideringtheimpactoftheseparametersontheyield,selectivity,andefficiencyofo-CBAsynthesis.
