    Abstract: In Examples 5 and 8, nitrobenzene is hydrogenated to aniline in presence of hollow silica beads impregnated with copper, at temperatures of 280 DEG -290 DEG C.ALSO:Catalysts or catalyst carriers in the form of hollow beads are prepared by spraying a hydrogel containing at least 30% by weight of water and/or a suspension and/or a solution of metal compounds at a pressure of 10 to 100 atmospheres into a tower-shaped vessel, and cocurrently introducing a gas at 300 DEG to 700 DEG C. in amounts of 4 to 18 cubic meters per kgm. of initial material. Hydrogels of silicic acid, alumina, silicates and titania are mentioned, Al, Mg, Zr or Zn salts may be added in preparing a silicic acid hydrogel. The metal compounds may be compounds of Cu, Ag, Zn, Mg, Al, Sn, Pb, V, Cr, Mo, W, Mn, Fe, Ni, Co, Pt or Pd. The hollow beads may be treated with halogen or a phosphoric acid. Examples relate to (1), (5) silica gel; (2), (3) alumina gel; (4) aluminium phosphate; (6) alumina + Co + Mo; (7) Mo + P + V; (8) silica gel + Cu.ALSO:Catalysts or catalyst carriers in the form of hollow beads are prepared by spraying a hydrogel containing at least 30% by weight of water and/or a suspension and/or a solution of metal compounds at a pressure of 10 to 100 atmospheres into a tower-shaped vessel, and cocurrently introducing a gas at 300 DEG to 700 DEG C. in amounts of 4 to 18 cubic meters per kgm of initial material.

A reactor for hydrogenation of nitrobenzene has diameter to height ratio 1:4 and has twenty two-component nozzles arranged at three levels above the grate at the bottom of the reactor. The upper portion of the vessel is widened to 1 1/2 times and includes a cyclone; reaction gases leaving by the cyclone are recycled via a heat exchanger, condenser, gas-liquid separator, preheater and pump. Cooling tubes are arranged in the catalyst layer at a distance from the wall of the reactor.

    Abstract: The invention comprises compounds of the formulae: (R1R2N-CH2-CH2-SO2-O-) 2R, or wherein R1 and R2 represent hydrogen or an alkyl, alkenyl, cycloalkyl, hydroxyalkyl, aralkyl, aryl or -CH2-CH2-SO2-O-R radical, or jointly with the nitrogen atom represent a heterocyclic radical, R represents a tetrahydronaphthyl radical or an aryl radical which may be optionally substituted, e.g. by alkyl, chlorine, bromine or carboalkoxy, and R3 represents an alkylene radical, and salts of such compounds, e.g. with hydrochloric, sulphuric, formic and acetic acids. The above compounds are prepared by reacting a , b -unsaturated sulphonic esters of the formula R-O-SO2-CH=CH2 with ammonia, hydrazine or an appropriate amine. Specification 910,377 is referred to.ALSO:A fungicidal composition comprises an aminoethyl sulphonic ester of the formul : - or wherein R1 and R2 represent hydrogen or an alkyl, alkenyl, cycloalkyl, hydroxyalkyl, aralkyl, aryl or -CH2-CH2-SO2-O-R radical, or jointly with the nitrogen atom represent a heterocyclic radical, R represents a tetrahydronaphthyl radical or an aryl radical which may be optionally substituted, e.g. by alkyl, chlorine, bromine or carboalkoxy, and R3 represents an alkylene radical, or a salt of such compounds, e.g. with hydrochloric, sulphuric, formic or acetic acid, together with an inert solid or liquid diluent or carrier and, if desired, a dispersing or wetting agent. They may be used in admixture with other active ingredients, e.g. acaricdies, insecticides, ovicides, herbicides, fungicides and bactericides. Specification 910,377 is referred to.
