  • Process for the production of epoxide resins
    Patent number: 4306054
    Abstract: The invention relates to the continuous production of epoxide resins of low, medium and high molecular weight, and also to their purification and to that of the waste water. No raw materials are required in addition to epichlorohydrin, 2,2-bis-(4-hydroxyphenyl)-propane, alkali hydroxide and water. The raw materials are fed at a shear rate of 7.5-50.times.10.sup.4 sec.sup.-1 (at a peripheral speed of the rotor of 15 to 50 m/sec and a distance of the rotor elements from the stator elements of 0.01 to 0.02 cm) continuously into a reactor and mixed in such a way that by the concentration of high kinetic energy in a very limited space the interfaces of the phases of the heterogeneous reaction mixture are increased to an extreme extent and the reagents are caused to react with one another within 5 sec. at the latest.The reaction proceeds very evenly in the reactor.
