Abstract
A process for producing surfactant products by reacting, in a jacketed vacuum neutralizing reactor, the acid form of an anionic surfactant with a neutralizing agent, and supplementing heat to the reactor via a heat transfer medium on the jacket, which is not cooling water. The surfactant product made by such a process may exhibit a solids concentration of from about 50% by weight or greater. A vacuum reactor that has a heating jacket using a heat transfer medium, such as steam, that is not cooling water, and can function both as a neutralizing reactor and an evaporator is also contemplated.
