Title (EN) BETA-MERCAPTOETHANOL SYNTHESIS
(FR) SYNTHÈSE DE BÊTA-MERCAPTOÉTHANOL
Abstract:
(EN) A process includes reacting, in a reactor having a fixed bed containing a solid catalyst which contains a heterogeneous ion exchange resin, hydrogen sulfide and ethylene oxide in the presence of the solid catalyst to yield a reaction product which contains beta-mercaptoethanol. A reactor system includes the reactor, an ethylene oxide stream, a hydrogen sulfide stream, a fixed bed containing the solid catalyst placed in the reactor, and an effluent stream containing the reaction product. During steady state operation of the reactor in the process and the reactor system, the hydrogen sulfide and the ethylene oxide are present in a mole ratio in a range of about 9:1 to about 20:1.
(FR) La présente invention concerne un procédé consistant à faire réagir, dans un réacteur comprenant un lit fixe contenant un catalyseur solide qui contient une résine échangeuse d'ions hétérogène, du sulfure d'hydrogène et de l'oxyde d'éthylène en présence d'un catalyseur solide pour donner un produit de réaction qui contient du bêta-mercaptoéthanol. Un système de réacteur comprend le réacteur, un courant d'oxyde d'éthylène, un courant de sulfure d'hydrogène, un lit fixe contenant le catalyseur solide placé dans le réacteur, et un courant d'effluent contenant le produit de réaction. Lors du fonctionnement à l'état d'équilibre du réacteur dans le procédé et le système de réacteur, le sulfure d'hydrogène et l'oxyde d'éthylène sont présents dans un rapport molaire compris dans une plage d'environ 9:1 à environ 20:1.
