| 摘要 |
The present invention is a synthesizing method of xylylenediamine (m-XDA) by halogenating xylene to attach halogen to methyl group and then by substituting halogen to -NH2 at relatively low temperatures using an aminating agent. Low operating cost comparing to a hydrogenation method, since the reaction can be made at low temperatures, atmospheric pressure, or low pressure so that investment cost of facilities does not nearly occur, is an advantage of the present invention. |
