Abstract:The traditional synthesis method of m-phthalaldehyde with chlorination and catalytic oxidation was improved on the basis of current producing process of m-phthalaldehyde. The results showed that the yield of the product reached more than 50.2%,which was 11% higher than that obtained in the traditional method,with a purity of over 99.6%. The improved method markedly decreased cost of product. |
Key words:m-phthalaldehyde;synthesis;hexamethylene tetramine |
