Abstract
Carbonyl sulphide, COS, is prepared by reacting CO and S vapour in molar ratio 0,5-2:1 at 500-900 DEG F. in the presence of a dehydrated crystalline alumino-silicate catalyst having rigid three-dimensional networks made up of unit cells characterized by absence of change in unit cell dimensions upon dehydration and rehydration, and a sorption capacity at 760 mm. and 25 DEG C. of at least 4% of n-butane. Pressure may be atmospheric-50 psig. and space velocities 5-25,000 v/v/hr. Catalysts may be zeolitic molecular sieves, e.g. Na12(AlO2)12(SiO2)12, 27 H2O, Na86[(AlO2)86(SiO2)106 267H2O, or the corresponding Ca salts. CO enters externally heated jacket 11 at 12 and flows through molten S and aperture 13 to cylindrical reactor 10. Further CO may be added at 15 and the mixture flows through catalyst on sintered disc 14. The <PICT:0885871/III/1> resulting mixture flows through S condenser 18 maintained at 120 DEG C. by steam in jacket 19, and condensed S is separated in 22. Remaining gas is condensed in trap 25 at -78 DEG C. and COS is distilled from column 27 at 28.
