Abstract
The invention discloses a kind of sulfonation cyclization technique for synthesizing acesulfame potassium for continuous production without stirring and special equipment for this technique. An injection pump is adopted to directly inject the sulfonation raw material and sulfonating agent into autoclave for sulfonation cyclization reaction under high velocity. Moreover, the reciprocating pump is adopted to deliver part of materials in autoclave to condenser designed outside the autoclave for cooling, followed by delivering the cooled materials to another input end of injection pump which together with sulfonation raw material and sulfonating agent is injected into autoclave through high-velocity injection by injection pump. The apparatus is composed of autoclave, injection pump, reciprocating pump and condenser.
