CA 2278666

A reactor (5, 15, 301) and process for the production of oxirane compounds by reaction of an olefin such as propylene with an organic hydroperoxide using a solid contact catalyst, characterized by the following features: (1) the reactor is divided into a series of separate zones (8, 10, 16, 19, 304, 311), each zone (8, 10, 16, 19, 304, 311) containing a bed of solid epoxidation catalyst; (2) about 25-75 % of the heat of reaction is removed by preheating cold reactor feed by direct contact with a heated recycle stream from the reactor; and (3) about 25-75 % of the heat of reaction is accounted for by a reaction mixture temperature rise of 20-100 °F and by vaporization of 15-40 of the net reactor product.

L'invention concerne un réacteur (5, 15, 301) ainsi qu'un procédé de production de composés oxiranne, lequel procédé consiste à faire réagir une oléfine, telle qu'un propylène, avec un hydroperoxyde organique, à l'aide d'un catalyseur solide de contact, et est caractérisé en ce que: (1) l'on a divisé le réacteur en une série de zones séparées (8, 10, 16, 19, 304, 311), chaque zone (8, 10, 16, 19, 304, 311) contenant un lit d'un catalyseur d'époxydation solide, (2) l'on a ôté environ 25 à 75 % de la chaleur de la réaction en préchauffant le courant d'alimentation froid du réacteur, en mettant ce courant en contact direct avec un courant de recyclage chauffé provenant du réacteur, et (3) l'on obtient environ 25 à 75 % de la chaleur de réaction en élevant en température le mélange de réaction, de 20 à 100 DEG F et en vaporisant 15 à 40 % du produit net du réacteur.
