G. Krummrich Plant has be . made using phenol from the sulfonation process. In approxink: 2y two years, sulfonation phenol facilities will probably be ret/\,-ed. A plant test is required to determine the effect of cumene phenol on the process, and if it has any effect on 2 , 4-dlchlorophenoxy- acetic acid. DISCUSSION Laboratory results shows the finished crude 2,4-dichlorophenol to be dark amber rather than light amber. The 2, 4-dichlorophonoxyacetic acid prepared from cumene 2, 4-DCP in the lab is equivalent to that from sulfonation 2, 4-DCP in appearance, color, odor, yield quality, and reaction rates. The red color from the cumene 2, 4DCP remains in the mother liquor stream. K n u no* Tentative Amendment "A" 2- - SAFETY No change. QUALITY Color will"be dark amber rather than light amber.
