Abstract：
 The present invention relates to a superbranched polyquaternary ammonium salt and its preparation method. Said method includes the following steps: firstly, using tertiary amine with dihydroxyl group or trihydroxy group as raw material to synthesize halogenated monoquaternary ammonium halate with two functionalities or three functionalities, then using dichloromethane as tracting agent of synthesize halogenated tertiary amine self-body with two functionalities or three functionalities, finally adding zeolite, heating and making reflux reaction so as to synthesize the invented superbranched polyquaternary ammonium salt. It can be directly used in the various places of phase transfer catalysis, nano-grade catalysis, reactor, immunodiagnosis reagent, medicine and gene vector, etc. or after having been modified it can be used in the above-mentioned various places.
