Abstract: p-Menthane-1,8-diamine (MDA) is an important intensive-processing product of turpentine having similar framework of terpenediol hydrate. This paper summarized its special physical properties, and reviewed the research progress on its applications, such as curing agent of epoxy resin, bacteriostatic agent in soap, agents in polyamd resin and polyurethane, catalysts for condensation reaction of silicon-bonded hydroxyl groups, copolymer for improving dyeing ability of polyolefin textile fibers and assistant in some reaction processes.
