Abstract: A method for the epoxidation of an olefin comprising reacting a feed gas composition containing an olefin, oxygen, and a halocarbon moderator having a first moderator concentration M1 in the presence of an epoxidation catalyst at a first temperature T1; increasing the first temperature to a second temperature T2; and increasing the first moderator concentration to a second moderator concentration M2, wherein the second moderator concentration is defined by: M2=M1(1+r)T2−T1 wherein the temperature has the units of degrees Celsius, and r is a constant factor which is in the range of from 0.001% to 100%.

Abstract translation: 一种烯烃的环氧化方法，包括在环氧化催化剂的存在下，在第一温度T1下使包含烯烃，氧和具有第一缓和剂浓度M1的卤化碳慢化剂的进料气体组合物反应; 将第一温度升高到第二温度T2; 并且将第一减速剂浓度增加到第二减速剂浓度M2，其中第二减速剂浓度由以下定义：M2 = M1（1 + r）T2-T1其中温度具有摄氏度的单位，r是常数因子 在0.001％至100％的范围内。
