Reflux temperature of toluene
WebIf the reaction is carried out, for example, with toluene, which is less dense than water, the steam in the reflux condenser will consist of an azeotropic mixture of toluene and water. When this mixture is condensed, it falls into the so-called Dean-Stark, forming two layers: the top layer will consist of toluene and the bottom layer water ... WebAn azeotropic mixture of toluene and water distills out of the reaction, but only the toluene (density=0.865 g/ml) returns, ... 24% water and 8% alcohol at reflux temperature and the organic layer in the trap contains 86% ester, 11% alcohol and 3% water which is reintroduced. The water layer is 97% pure.
