The invention relates to the technical field of tetramethyltin synthesis, in particular to a high-efficiency tetramethyltin synthesis process which comprises the following steps: S1,
material selection and preparation: selecting corresponding raw materials according to tetramethyltin synthesis requirements, dividing the raw materials into main materials, auxiliary materials and additives, and subsequently weighing the raw materials by using a weighing device; s2, material pretreatment: adding the weighed main material into a
dehydration device, starting the
dehydration device to carry out
dehydration treatment, detecting after dehydration is finished, and taking out the dehydrated main material when a detection result meets a standard; by introducing the double-stage design of low-temperature catalytic
methylation and gradient heating reaction and combining a
dimethyl sulfide catalytic
system to replace a traditional
iodine initiator and
magnesium powder dynamic equilibrium mechanism, the reaction heat release rate is greatly reduced, the temperature in the whole reaction process is kept in a constant range, the material flushing or explosion risk caused by local overheating is thoroughly eliminated, and the product quality is improved. And intrinsically safe production is realized.
