    摘要： A process for preparing ethylene oxide by reacting ethylene with oxygen in the presence of a catalyst composition comprising a support having a surface area of at least 500 m 2 /kg, and deposited on the support:
    - silver metal,
    - a metal or component comprising rhenium, tungsten, molybdenum or a nitrate- or nitrite-forming compound, and
    - a 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 (Q K / R) + Q HIA is in the range of from 1.5 to 30 mmole/kg, wherein Q HIA and Q K 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 Q HIA to Q K is at least 1:1, the value of Q K 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,
    wherein a feed comprising ethylene and oxygen is contacted with the catalyst composition, and the feed comprises carbon dioxide, in addition to ethylene and oxygen, in a concentration in the range of from 0.5 to 2 mole-%, relative to the total feed.

    摘要： To provide a novel method for producing an isothiocyanate compound having a carboxyl group(s) from the corresponding amino compound having a carboxyl group(s).
    A method for producing an isothiocyanate compound which has a carboxyl group(s) and is represented by the formula (2). And the method comprises reacting an amino compound which has a carboxyl group(s) and is represented by the formula (1) (wherein A is e.g. a C 6-14 aromatic hydrocarbon group or a C 1-12 saturated hydrocarbon group, and B is e.g. a single bond, a C 6-14 aromatic hydrocarbon group or a C 1-12 saturated hydrocarbon group), in a solvent, with carbon disulfide (CS 2 ) and then with a halogen as a simple substance.
