Title: A process for preparing unsaturated monocarboxylic acids from olefins
IPC: B01J27/19
Filed: 1962-04-19
Abstract: Unsaturated monocarboxylic acids are prepared by oxidising an olefine in the vapour phase in a single stage with molecular oxygen, in the presence as a catalyst of phospho-molybdic acid in admixture with arsenic or an arsenic containing compound. Propylene and/or isobutylene are converted to acrylic and methacrylic acids respectively and an inert diluent may be present.  Arsenic may be present as oxide, arsenide, halogen or sulphur compounds or mixtures thereof, and part or all may be combined with molybdenum e.g. as arsenomolybdic acid.  Other metals e.g. Fe, Cu, Pb, Co, Ni W, and Sb or oxides thereof may also be present. The catalyst may be supported on conventional carriers and in the form of a solid fixed bed, as a suspension, or as a fluid catalyst bed, and the process may be continuous. Examples describe the oxidation of propylene to give a mixture of acrylic acid, acrolein and minor amounts of acetic acid, acetaldehyde, maleic acid, acetone and oxides of carbon, which may be recycled to increase the acrylic acid yield.  Specifications 822,140 and 939,713 are referred to.ALSO:An oxidation catalyst consists essentially of phospho-molybdic acid in admixture with arsenic or an arsenic-containing compound. The phospho-molybdic acid component may be made by reacting molybdenum trioxide on sodium molybdenum trioxide with phosphoric acid or may be the commercially available acid.  The arsenic, preferably in the range 0,1-10%, may be in the form of oxide, acid, metallic arsenide, and halogen or sulphur compounds, or in combination with molybdenum.  Metals, e.g. Fe, Cu, Pb, Co, Ni, W, may also be present together with fillers and/or carriers, such as aluminas, silica-alumina, or silicon carbides.  Examples describe the preparation of the catalysts and the oxidation of olefines to unsaturated monocarboxylic acids.  Specifications 822,140 and 939,713 are referred to.

Patent GB-387324-A (GB)
Title: Improvements in compositions for bituminous roads
Filed: 1931-05-26
Abstract: A porous friable material such as coke, porous stone, crushed brick, &c. is added to a hot-mix bituminous road-making composition to absorb excess binder so that the composition is manipulable on cooling.  The binder is subsequently released by the crushing of the absorbent material after the composition has been laid.  Preferably the absorbent is added to the sand or fine portion of the aggregate and this mixture is treated with bitumen; the coarse aggregate is separately coated with binder, and the two components are finally mixed together.  The absorbent may, however, be added to the aggregate before the binder.  Cold sand may also be added to the hot mix to assist in the absorption or concealment of the binder.  The proportion of binder may be 4-12 per cent of the total composition and that of absorbent 2-8 per cent.  The invention is not restricted to compositions containing coarse aggregate but extends also to sand and like mixes for surface dressings.  The use of quarry fines as a substistute for sand is mentioned.
