Abstract: 1,066,124. Gas analysis. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 21, 1965 [May 21, 1964], No.21733/65. Heading G1B. A method of analysing a gaseous mixture comprises the steps of trapping a volume of the mixture in a vessel 4, cooling the vessel e.g. by use of liquid nitrogen until its temperature is lower than the sublimation temperature of all the components in the mixture whose concentration is to be measured, and measuring during reheating of the vessel 4, the amplitude of the sharp rises in pressure due to the passage from the solid to the gaseous state of each component in turn. The gaseous mixture is circulated through the vessel 4 which contains a baffle 6 from a conduit 10 to a conduit 12 and valves 14, 16 are closed to trap a volume of the mixture in the vessel. A liquefied gas is supplied via a conduit 24 to a tank 22 surrounding the vessel 24 to cool it and solidify therein all the mixture components which it is desired to determine. The vessel 4 is then allowed to warm up, which process may be aided by use of an electrical resistance 28, and the pressure in the vessel is recorded by a recording manometer 18. A correction factor must be applied to the results to allow for the fact that the sublimated gases are at the temperature of the vessel 4. In a modified embodiment to avoid this the vessel is formed as two enclosures, one of small volume in the tank, and the other of e. g. one hundred times the volume of the first, kept at a constant temperature, preferably atmospheric. In this way the gases in the mixture are solidified in the enclosure of small volume but when sublimated are kept at substantially a constant temperature.

Patent GB-826545-A (GB)
Title: Production of conjugated diolefins
Inventor: OLDHAM WILFRED JOHN
IPC: C07C2/86
Filed: 1957-07-10
Abstract: Conjugated diolefines are prepared by reacting acetaldehyde or formaldehyde with a monoolefine of not more than 6 carbons in the vapour phase over an acidic surface-active clay catalyst.  The mono-olefine is preferably a tertiary olefine and may be isobutene, 2-methylbutene-2 or 2-methylbutene-1.  Formaldehyde may be introduced as industrial formalin containing 36-40% by weight of formaldehyde or as compounds which give rise to formaldehyde under the reaction conditions, e.g. trioxane and paraformaldehyde.  The proportion of aldehyde in the reaction zone is preferably below 10 mol. per cent and this may be achieved by using an inert diluent such as nitrogen, a lower paraffin, carbon dioxide or steam.  Reaction temperatures of 150-400 DEG  C. can be used with space velocities of 0.5-50 mols. of aldehyde per litre of catalyst per hour.  Any pressure may be used but atmospheric or just above is preferred.  The catalyst may be an acid-activated montmorillonite, bentonite, fuller's earth. vermiculite, attapulgite, kaolinite or illite and may be used in fixed, moving or fluidized beds.  The catalyst is easily regenerated by heating in air to remove carbon.  The formation of isoprene from isobutene and formaldehyde is exemplified. Specification 826,546 is referred to.
