Various embodiments disclosed relate to methods and apparatus for synthesizing various biphenols. In various embodiments, the present invention provides a method of making a bisphenol including feeding a phenol at or proximate to the first end of a reactor column including a first end and a second end and including a solid catalyst distributed in multiple locations between the first end and the second end of the reactor column. The method includes feeding an oxomethylene compound to the reactor column at a first location that is at or proximate the first end and at one or more additional locations between the first location and the second end of the reactor column, and removing at least some water from the reactor column. The method includes removing a product composition including a diphenolmethylene product at or proximate to the second end of the reactor column.
