Is sulforaphane a form of sulfuric acid
WitrynaThe second step in making sulfuric acid from the resulting “Scrubber Feedstock” is removing any impurities that are still present from the smelting process; purity and accuracy of grade are the primary goals of sulfuric acid production. The Contact Process, described here, is almost universally used to convert SO2 to sulfuric acid … WitrynaThe sulfonic acid is taken up by the organic solution of a tertiary amine which is then separated from the aqueous solution. The purified sulfonic acid can then be readily stripped from the amine by known techniques. It is therefore one object of this invention to provide a method of separating sulfonic acids from sulfuric acids and sulfates.
