The invention provides a methyl chloroacetate synthesis process which comprises the following steps: firstly, methanol and preheated chloroacetic acid are fed into a tower kettle of a reactive distillation tower for reaction to obtain a reaction system, then the reaction system is rectified through the reactive distillation tower to obtain a rectified system, and the rectified system is discharged from the tower top of the reactive distillation tower to obtain methyl chloroacetate. Carrying out condensation and oil-water separation to obtain a heavy phase; and finally, feeding the heavy phase obtained in the previous step into a crude ester refining rectifying tower to rectify again, and extracting from the bottom of the crude ester refining rectifying tower to obtain methyl chloroacetate. The invention also provides a methyl chloroacetate synthesis system. The methyl chloroacetate synthesis process designed by the invention is a novel continuous low-energy-consumption methyl chloroacetate ...
