Gene ral Offices June 16, 1959 2 / 3 7 *- CKLOHACKE PROBLEM - GZRKAT P.TICIZ Reference : Your r.eno 6/c/p9 Mr. L. C. Weger Nitro, Vest Va. 5 i/MJ 5. T tfk --1 LUDfii&A/i/JO R M & t J I certainly thank you for the translation of the German article on chloracne. I wish we had been able to investigate the previous difficulties completely enough to isolate the chlorinated dlbenzodioxine (dlphenylenedloxide) as an important causing agent. Similarly, we would have been quite pleased if Monsanto research or that at Mellon Institute or Kettering Laboratory had developed the information on the 2,3,6,7-tetrachlorodibenzodioxine. The article appears to bear out Dr. Oettel1s state ment in 1956 that he believed that a chlorinated di phenyloxide was responsible and that such materials could be produced in any process of chlorination of phenol* n r 1 . : c:uv, Einer P.
