Step up sulfonation efficiency. "Sulfan" has 99.5% S 0 3 available for sulfonation reactions. For many applications, "Sulfan" offers nine times as much usable SO3 as 100% sulfuric acid . . . over three times a s much as 20% oleum. This can mean a considerable saving in operating costs.
TO S T E P UP EFFICIENCY OF SULFONATIONS,
Step up processing efficiency. With "Sulfan," there is no waste acid. This means t h a t 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 sulfonation, the waste acid problem inherent with use of sulfuric acid or oleum is eliminated.
These benefits alone make "Sulfan" worth
