PURPOSE: A synthesis method of phosphonium based-ionic liquid which includes small amount of halide using a micro reactor is provided to efficiently relieve complex reaction condition of the manufacturing method. CONSTITUTION: A synthesis method of phosphonium based-ionic liquid includes a step of reacting cation - provided phosphonium compound with dimethyl sulfate, trifluoro methane sulfate, or negative ion-provided compound of iodine alkane by using a micro reactor. The cation - provided phosphonium compound is trimethyl phosphine, triethylene phosphin, tripropylphosphine, tributyl phosphine or triphenylphosphine. The manufacturing method includes a step of separately vacuum evaporating the ionic liquid which came out after being reacted. The application concentration of the cation - provided phosphonium compound is 0.0002-1.0 mole, and the application concentration of the negative ion - provided compound is 0.0002-1.0 mole.
