| titleOfInvention | New carbon catalysts and their use in the preparation of vinyl esters |
| abstract | A carbon catalyst for use in certain vinylation reactions (see Group IV(b)) is prepared by irradiating active carbon with ionizing radiation and if desired thereafter impregnating with a Group IIb metal compound, e.g. zinc acetate, zinc formate, zinc propionate, zinc chloride, zinc oxide, cadmium acetate, mercuric acetate and mercuric chloride. Specified radiations are g -rays from a cobalt-60 source and an electron beam from a Van de Fraaf accelerator, the preferred quantity of radiation being between 104-1010 Roentgen. For impregnation, the irradiated active carbon is immersed for a day in an aqueous solution of the metal compound at room temperature and dried.ALSO:Vinyl esters are produced by reacting a carboxylic acid or hydrogen chloride with acetylene in the presence of an active carbon catalyst which has been irradiated with an ionising radiation and preferably then impregnated with a compound of a Group IIb metal. Metal compounds specified are zinc acetate, zinc formate, zinc propionate, zinc oxide, cadmium acetate, mercuric acetate and mercuric chloride. The preferred quantity of radiation is between 104-1010 Roentgens. In examples active carbon is irradiated with g -rays from a cobalt-60 source or an electron beam from a Van de Graaf accelerator and impregnated with a zinc salt by immersing it in a solution of the salt for a day at room temperature and used as a vinylation catalyst for the vapour phase reaction of acetylene with acetic acid, propionic acid and hydrogen chloride at temperatures in the range of 135-200 DEG C. |
