A continuous reactor was developed for industrial production of monodispersed alumina particles from the metal alkoxide. Taylor vortex flow was used for solution mixing. Individual Taylor vortices served as batch reaction vessels. Monodispersed spherical alumina particles were prepared by the hydrolysis of aluminum alkoxide in the mixture oF octanol and acetonitrile. Monodispersed alumina particles were continuously produced for 5 h by the reactor. The particle size and distribution were comparable to those obtained by a batch process. The effects of Taylor number (Ta) and residense time on the particle size, particle size distribution, yield, and particle number density of monodispersed alumina particles were investigated. Monodispersed alostina Particles wcrc obtained at Ta number from 50 to 150.
