    Abstract: Propane is ammoxidised in the gas phase by contacting with oxygen, ammonia and, if desired, water, in the presence of a catalyst based on iron, antimony and oxygen under elevated temperature and pressure, using a catalyst represented by the formula E d Fe a Sb b O c I where E is vanadium, chromium and/or niobium, a is 1, b is a real number from 1 to 8, c is a real number from 2.5 to 18, and d/c is in the range from 0.01:1 to 1:1.

    Abstract: Acrylonitrile is prepared by a process which comprises the ammoxidation of propylene with ammonia and molecular oxygen or a gas containing molecular oxygen at from 300 DEG to 600 DEG C. in the presence of a metal oxide catalyst which contains tellurium and one or more of the metals iron, molybdenum and antimony, in a fluidized bed, with regeneration of the catalyst during the reaction by the addition of oxidic tellurium compounds or tellurium compounds which form oxidic tellurium compounds under the reaction conditions, in dissolved or suspended form.

    Abstract: A briquette, which is easily pierceable and supportable, comprises compacted particulate material and has an outer region ( 1 ) and an inner region ( 2 ), said inner region ( 2 ) being provided with a well ( 3 ) having a diameter which decreases progressively in a non-linear relationship with increasing distance from the top of the well such that the sides of the well extend convexly into the well. The briquette, preferably, is a rodenticide block although it may, instead, be a block for sanitary, and/or domestic use. The briquette may be manufactured by compacting particulate material into the nip between a first rotating roll, having a surface provided with a suitable mould, and a second, counter-rotating roll.
