<P>PROBLEM TO BE SOLVED: To provide a method for producing a methylenedianiline (MDA) derivative. <P>SOLUTION: The method for producing a methylenedianiline derivative expressed by formula (II) comprises allowing a compound expressed by formula (I) to react in the presence of zeolite. In formula (I), each R independently represents a hydrogen atom, a methyl group, an ethyl group, a linear or branched alkyl group having 3 to 8 carbon atoms, a cycloalkyl group having 4 to 10 carbon atoms or an aryl group having 6 to 12 carbon atoms. In formula (II), each R independently represents a hydrogen atom, a methyl group, an ethyl group, a linear or branched alkyl group having 3 to 8 carbon atoms, a cycloalkyl group having 4 to 10 carbon atoms or an aryl group having 6 to 12 carbon atoms, and n represents an integer of 1 to 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
