A* Step up sulfonation efficiency. "Sulfan" has 99.5% S 0 3 available for sulfonation re actions. For many applications, "Sulfan" offers nine times as much usable SO3 as 100% sulfuric acid . . . over three times as much as 20% oleum. This can mean a con siderable saving in operating costs.

S t e p up p r o c e s s i n g e f f i c i e n c y . W i t h "Sulfan," there is no waste acid. This means that you can increase batch sizes or get more rapid t h r o u g h - p u t . . . often double without increasing size of equipment! Since no water is formed when "Sulfan" is used for sulfona tion, the waste acid problem inherent with use of sulfuric acid or oleum is eliminated.
These benefits alone make "Sulfan" worth your thorough investigation. You may be able to realize other i m p o r t a n t process economies and advantages too.
