摘要：
A catalyst composition comprising a support having a surface area of at least 500 m2/kg, and deposited on the support:silver metal,a metal or component comprising rhenium, tungsten, molybdenum or a nitrate- or nitrite-forming compound, anda Group IA metal or component comprising a Group IA metal having an atomic number of at least 37, and in addition potassium,wherein the value of the expression (QK/R)+QHIA is in the range of from 1.5 to 30 mmole/kg, wherein QHIA and QK represent the quantities in mmole/kg of the Group IA metal having an atomic number of at least 37 and potassium, respectively, present in the catalyst composition, the ratio of QHIA to QK is at least 1:1, the value of QK is at least 0.01 mmole/kg, and R is a dimensionless number in the range of from 1.5 to 5, the units mmole/kg being relative to the weight of the catalyst composition.
