Abstract
The continuous preparation of epoxy resins of low, moderate and high molecular weight is carried out from epichlorohydrin, 2,2-bis(4-hydroxyphenyl)propane, alkali metal hydroxide and water without further starting materials. The raw materials are mixed vigorously and continuously in a reactor at rates of from 15 to 50 ms<-1> in a very small space, where they are reacted in a maximum of 5 s at temperatures of from 60 to 180 DEG C. The reaction is optionally continued in a second reactor, in which case it is possible for only a proportion of the reaction participants to be reacted in the first reactor, while the remainder are added in the second reactor. The resultant resins and the effluent can be extracted in countercurrent with water or organic solvents in a pulsation unit.
