    摘要: The invention relates to a process for producing 5-nonyl salicylaldoxime that comprises of converting nonyl phenol to a 5-nonyl aldehyde in a two-step reaction using a novel catalyst mixture, followed by the oximation of the said aldehyde using hydroxylamine sulphate, and that the said catalytic process of aldehyde production is the main invention, in that the effective use of the catalyst mixture helps the reaction proceed at a faster and controlled rate which leads to a higher yield of aldehyde, as a result of complete conversion of all the reactants to the final products.
