Monsanto industrial chemicals co. ....< . pt r Cova T3C 1 < i i i March 25, 1974 SPECIFICATIONS FOR MONOCHLOROBIPHENYL TO K. R. Richard T3A H. S. Bergen - B2SL T. L. Cossagc - BISL C. Paton * B2SC J. R. Savage - B2SL The present specifications for polychlorobiphenyls (PCBs) in Monochlorobiphenyl (MCBP) are a maximum of 1.04 and 1.34 for lov;-para and high-para MCBP, respectively. Most of this PCB is 2,2'-Dichlorobiphenyl. The samples ve have generated in the laboratory have been found to contain 440 to 500 ppm of PCBs other than 2,2'-Dichlorobiphenyl. V'ould there be an advantage to us to split this out in the specifications? The new specifications would be as follows: Low-Para MCBP High-Para MCEP Biphenyl o-Chlorobiphenyl m-Chiorobiphenyl p*Chlorobiphenyl 2,2'-Dichlorobiphenyl All other PCBs 0.64 max. 60.04 min. 4.04 max. Remainder 0.94 max. 0.14 max. 0.64 max. 75.04 min. 5.54 max. 14.04 min. 1.24 max. 0.14 max. &A D. R. Cova HONS 021732
