The present invention relates to flameproof fabrics based on melarnine resin fibres, fireproof blankets and clothing made therewith and their use for extinguishing fires and protecting people and objects from fire, combustion products and/or extinguishing agents.

Flameproof fabrics based on melamine resin fibres

Metal coated melamine resin fiber and natural fiber mixture

Catalyst based on oxides of Fe, Co, Bi and Mo

A process for regenerating deactivated metal oxide catalysts comprising at least one of the elements antimony, iron, bismuth, molybdenum, vanadium, tungsten and/or uranium and a peptizable carrier, comprises the steps of:

Regeneration of metal oxide catalysts

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.degree. to 600.degree. 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.

Preparation of acrylonitrile

A molded supported catalyst which contains from 2 to 13% by weight of copper ions in the form of copper(II) chloride and/or copper oxychloride and from 0.2 to 3% by weight of alkali metal ion on a columnar carrier and has a diameter of from 4 to 7 mm and a height which is from 0.35 to 0.75 times the diameter is particularly suitable for preparing 1,2-dichloroethane by oxychlorination of ethylene.

Molded supported catalyst

1,2-Dichloroethane is prepared by oxychlorination of ethylene in the presence of a catalyst which contains, on a conventional carrier, copper(II) chloride in a concentration such that the amount of copper ions is from 1 to 20% by weight, based on the total weight of the catalyst, by a process in which the catalyst is obtained by impregnating the carrier with an aqueous solution which contains copper(II) chloride and hydrogen chloride in amounts such that the weight ratio of copper ions to hydrogen chloride is from 13:1 to 130:1.
