A process for the preparation of alkylene oxide, which process involves passing a feed containing an organic hydroperoxide and alkene through a bank of at least two serially connected reactors containing epoxidation catalyst and withdrawing a product stream having alkylene oxide and an alcohol as reaction products, in which bank of reactors the temperature of the feed is controlled such that during operation the outlet temperature of the final reactor is at least 4&#xb0; C. higher than the outlet temperature of the first reactor.

Process for preparing alkylene oxide (epoxid, oxirane)

The invention relates to a process for preparing polymers by bulk polymerizing a monomer feedstock composed of styrene or styrene-like monomers and/or anionically copolymerizable comonomers employing an anionic initiator and a conventional spray-tower as reactor in the absence of a quenching solvent that fills the lower portion of the spray-tower, and the polymers so produced.
