'' f. 5442, mixture of chlorinated terphenyls, 42% Cl. y g. 5460-, mixture of chlorinated terphenyls, 60% Cl, The following information which we discussed will be very helpful: GLC data on one typical Arochlor; solubility in common organic solvents; technical bulletins on their uses and physical properties; and stability on storage, . . It would also te quite useful if you could Include any data you have on the elemental analysis, molecular weight range and the 'amount of unreacted biphenyl and terphenyl in these Arochlor mixtures. Does the chlorinated terphenyl mixtures include chlorinated m-terphenyl (1,3-diphenyl benzene) and o-terphenyl (1,2-diphenyl benzene) in addition to the p-terphenyl (1,4-dlphenyl benzene)?

These bulletins contain Information on sol ubility In cotanon solvents and physical properties. To preserve the highest quality as for dielectrlcal Insula tion use the Aroclora are beat stored In opaque con tainers at normal storage conditions. In addition, l have included a paper on QLC analysis of AroclorB by Ueingarten, Rosa, Schlater and Wheeler, The average chlorination value by weight Is reflected by the last two numbers of the four digit nutobert l,c*, Aroolor 1242 would have approximately *2$ by weight of chlorine. The amount of unreacted biphenyl and ter- phenyl will vary inversely with the degree of chlorina tion. Aroclor 1222 may contain 15* biphenyl; Aroclor 1252 may contain 8* biphenyl and Aroclor 1260 will have <0,13. ,. The chlorinated terphenyi products will contain a mix ture of chlorinated o, a, and p terphenyi. Clnoerely yours. WRRtms V. X.
