Procedure
600 g of m-cyanobenzylamine crude product (m-cyanobenzylamine 90% by weight, m-xylylenediamine 10% by weight) obtained by hydrogen reduction of isophthalonitrile in the presence of sponge metal nickel catalyst was added dropwise in 8 kg of water while stirring at room temperature for dissolution and the solution was left to stand overnight at 5C. The crystals which precipitated were filtered by centrifugation to obtain 783 g of m-cyanobenzylamine hydrate (water content: 48% by weight).
