1. A continuous method of forming a bisphenol A oil comprising:
- forming the bisphenol A oil by mixing a molten bisphenol A and water;
wherein the bisphenol A oil comprises 10 to 30 wt % water based on a total weight of the bisphenol A oil and is at a temperature of 100 to 140°
C.;
flowing at least a portion of the bisphenol A oil through an inline densitometer and measuring a real-time density and a real-time temperature of the bisphenol A oil;
determining a real-time concentration of the bisphenol A oil based on the real-time density and the real-time temperature.

12. A method for interfacially polymerizing a polycarbonate, comprising:
-
adding a bisphenol A oil, a carbonate compound, water, a water immiscible solvent, and a catalyst to an interfacial reactor, wherein the bisphenol A oil comprises bisphenol A and 10 to 30 wt % water based on a total weight of the bisphenol A oil and is at a temperature of 100 to 140°
C.; andduring the adding of the bisphenol A oil, flowing at least a portion of the bisphenol A oil through an inline densitometer; measuring a real-time density and a real-time temperature of the bisphenol A oil; and determining a real-time concentration of the bisphenol A oil based on said real-time density and said real-time temperature; and interfacially polymerizing the polycarbonate. - View Dependent Claims (13, 14, 15, 16, 17, 18)
