The invention relates to a method and equipment for producing trimethylsilyl trifluoromethanesulfonate, which belongs to the technical field of trimethylsilyl trifluoromethanesulfonate production. Themethod comprises the following steps of adding trifluoromethanesulfonic acid into a reaction kettle, dropwisely adding trimethylchlorosilane, reacting at 20-30 DEG C under 0.002-0.003 MPa for 8.5-10hours, carrying out reduced pressure distillation, and collecting 125-135 DEG C fractions, thereby obtaining the trimethylsilyl trifluoromethanesulfonate. The equipment comprises a reaction kettle anda quantitative tank, a fixed plate is fixed in the reaction kettle, a rotating rod is rotatably connected to the fixed plate, a motor fixed to the rotating rod is installed at the bottom of the reaction kettle, a stirring mechanism is arranged on the outer side of the rotating rod, and a titration opening is formed in the top of the reaction kettle and connected with a titration mechanism in a liquid inlet pipe at the bott
