<PICT:0993891/C2/1> An apparatus for the continuous mixing of solids and liquids (see also Division B1) may be used for the alkylation of phenols with olefins using a solid (e.g. ion-exchange) catalyst. The phenol and olefin are fed continuously through pipe 12 to the bottom of mixing chamber 24 which is heat controlled and in which are cation exchange resin beads 48. Propeller 34 causes liquid reaction product and solid catalyst to pass up through openings 28 into settling chamber 26; solid catalyst settles in cone 20 and falls back into the mixing chamber through opening 30 while reaction product overflows at 16.
