Oops, my mistake. I really should think twice about writing emails at 1:30am. In any case, can you comment on the proper desiccant to dry H2SO4 with?

Concentrated sulfuric acid (~98%) is 18 M or 18 molar. This does make a significance difference. an 18 M solution is 36 N or 36 normal, because sulfuric acid is diprotic. Hence a 18 N solution of sulfuric acid would only be about 50%, the remainder water. I doubt that it would work as a catalyst with the water present, because the acid stage appears to be very sensitive to the presence of water. H ------------------------ Yahoo!
