Abstract
In the preceding paper, the titrimetry of nonionics was established with both sodium tetraphenylborate and barium chloride. In this work, the composition of the nonionicsbarium-tetraphenylborate complex was studied by Morgan's method, Neu's method, and gravimetry. It was found that 6 moles of ethylene oxide combined with 1 mole of tetraphenylborate and 0.5 mole of barium in the complex in 10∼40 units ethylene oxide condensates and the titrimetry was applicable to the determination of the ethylene oxide content in nonionics.
