Document Type and Number:
Japanese Patent JP2011093837
Kind Code:
A
Abstract:
To provide a method for producing dimethylvinylsilyltriflate, by which the dimethylvinylsilyltriflate can stably be obtained from trifluoromethane sulfonic acid at a low cost without expensive silver trifluoromethanesulfonate and dimethyl ether having a low ignition point and without a solvent.
The method for producing the dimethylvinylsilyltriflate is characterized by mixing trifluoromethanesulfonic acid with 1,3-divinyl-1,1,3,3-tetramethyldisilazane to produce a neutral salt, thermally decomposing the neutral salt, and then distilling.
