Apparatus for producing methane sulfonyl chloride
Abstract
Abstract MEANS TO PROVIDE FLOW OF THE REACTION MATRIX FROM THE TOP OF THE COLUMN REACTOR FIRST TO THE COOLER, THEN TO THE SEPARATOR AND FINALLY THE LIGHTER PHASE FROM THE SEPARATOR TO THE BOTTOM OF THE COLUMN REACTOR. THE CONDENSER BEING MOUNTED AT AN ELEVATED POSITION ABOVE THE COLUMN REACTOR FOR GRAVITY RECYCLE OF CONDENSED LIQUIDS. APPARATUS FOR CONDUCTING A CONTINUOUS CHEMICAL REACTION COMPRISING IN COMBINATION: (A) A VERTICALLLY DISPOSED BAFFLED COLUMN REACTOR; (B) A COOLER; (C) A SEPARATOR; (D) A VENTED CONDENSER; AND (E) CONDUIT MEANS FOR FEEDING AND DISPERSING REACTANTS INTO THE COLUMN REACTOR AT A POSITION NEAR THE BOTTOM. THE BAFFLED COLUMN REACTOR, COOLER AND SEPARATOR ARE CONNECTED BY CONDUIT
