The invention relates to a preparation method of thermosensitive sensitizer. The preparation method is characterized in that methyl substituted phenol (metacresol, o-cresol or p-cresol) and dichloroethane have condensation reaction at the temperature of 70 to 80 DEG C, then the thermosensitive sensitizer 1,2-dimethyl phenoxyl ethane crude product with the purity of 95 to 98 percent (the main impurity is the single substituted phenoxyl ethane) is obtained in the steps of layering, continuous reaction, extraction and layering, and then the crude product is rectified to obtain the high-purity thermosensitive sensitizer. The method is simple to operate, environmentally friendly, high in yield, moderate in reaction condition and low in production cost; the extracted impurity can be used as the raw material to be continued in the reaction.
