NEW ROUTE TO PHTHALIC ACID!.
In a report to the Petroleum Division of the ACS, Dr. William G. Toland of the California Research Corporation recently announced the development of a new method for p r o d u c i n g Phthalic Acid, with the following over-all reaction : C6H4(CH3)2 + 6S + 4H 2 0 = C6H4(C02H)2 + 6H2S
Note that the presence of Sulphur right smack in the middle of this reaction is necessary for its comple tion. The Sulphur leaves the process at this point. The hydrogen sulphide can be oxidized to elemental Sulphur and returned to the initial reaction. It is thus operable in a closed cycle. According to Dr. Toland, who de veloped this new route to phthalic acid, the process is simple and cap able of high recoveries. Here is another good example of how strongly Sulphur is in the proc essing picture. Together with its many derivatives it enters into count less reactions.
