Abstract

Analysis of gas streams leaving ammoxidn. process, in which a mixt. of an aliphatic 2-6 (3-4) esp. 3C alpha-monoolefin, NH3 and O3 is passed through a solid ammoxidn. catalyst at ca. 260-621 (426-510) degrees C, to produce the corresp. unsatd. aliphatic nitrile (CH2:CHCN), comprises cooling part of the gas, adjusting to 176-233 degrees C (in a closed gas cycle), removing solids with dia. >5 (>1-2) esp. >1 mu m and analysing the filtered and temp.-conditioned sample. This gives a stable gas stream, which does not form solids which would block the pipes, filters, valves and similar appts. Analysis can be carried out rapidly, allowing better process control.
