EPOXIDATION CATALYST, A PROCESS FOR THE PREPARATION OF THE CATALYST AND A PROCESS FOR THE PRODUCTION OF AN OLEPHINE OXIDE, A 1,2-DIOL, A 1,2-DIOL ETHER, A 1,2-CARBONATE OR AN ALKANOLAMINE

摘要

epididation catalyst, a process for preparing the catalyst and a process for producing an olefin oxide, a 1,2-diol, a 1,2-diol ether, a 1,2-carbonate or an alkanolamine "a catalyst for epoxidation of an olefin comprising a vehicle and, deposited in the vehicle, silver, a rhenium promoter, a first co-promoter, and a second co-promoter; where the amount of rhenium promoter deposited in the vehicle is greater than 1 mmol / kg, based on the weight of the catalyst; the first co-promoter is selected from sulfur, phosphorus, boron and their mixtures; the second co-promoter is selected from tungsten, molybdenum, chromium and their mixtures; and the total amount of the first and second co-promoter deposited in the vehicle is a maximum of 3.8 mmol / kg, in relation to the weight of the catalyst; a process for preparing the catalyst; a process for preparing an olefin oxide through the reaction of a feeder comprising an olefin na and oxygen in the presence of the catalyst; and a process for preparing a 1,2-diol, a 1,2-diol ether, a 1,2-carbonate or an alkanolamine.
