Description
Предметом изобретени вл етс способ получени медно-хром-окисного катализатора дл каталитического восстановлени органических соединений путем осаждени медноаммониевой соли хромовой кислоты с последующим термическим ее разложением .The subject of the invention is a method for producing a copper-chromium oxide catalyst for the catalytic reduction of organic compounds by precipitating a chromic acid copper ammonium salt, followed by thermal decomposition thereof.
Известно получение медно-хромокисного катализатора взаимодействием бихромата аммони с аммиаком и нитритом меди с последуюпд ,ей термической обработкой выпавшего осадка. Одиако этот способ дает небольшой выход катализатора .It is known to obtain a copper chromaoxidic catalyst by the interaction of ammonium dichromate with ammonia and copper nitrite with subsequent thermal treatment of the precipitated precipitate. Odiako this method gives a small yield of catalyst.
Особенность предлагаемого способа состоит в том, что медноаммогшевую соль хромовой кислоты осаждают в присутствии значительного избытка аммиака, благодар чему выход катализатора повышаетс на 50%.A feature of the proposed method is that the chromic acid copper muam salt is precipitated in the presence of a significant excess of ammonia, due to which the yield of the catalyst is increased by 50%.
Дл осунхествлени предлагаемого способа, к раствору двухромовокислого аммони прибавл ют аммиак в количестве, на 50% превышаюш ,ем то, которое требуетс дл In order to instill the proposed method, ammonia is added to the ammonium dichromate solution in an amount that is 50% higher than that required for
перевода бихромата в хромат. Затем к полученному раствору добавл ют нитрат меди. При этом осаждаетс медноаммониева соль хромовой кислоты.transfer of dichromate to chromate. Copper nitrate is then added to the resulting solution. This precipitates the ammonium ammonium salt of the chromic acid.
Осадок про.мывают и сушат при 100-110, затем подвергают термической обработке, после чего обрабатывают 10%-ным раствором уксусной кислоты, фильтруют, промывают водой и высушивают.The precipitate is washed and dried at 100-110, then subjected to heat treatment, then treated with a 10% solution of acetic acid, filtered, washed with water and dried.
Полученный медно-хром-окисный катализатор обладает посто нным стандартным качеством, по своей активности не уступающим лучшим образцам.The resulting copper-chromium oxide catalyst has a constant standard quality, in its activity is not inferior to the best samples.
Предмет изобретени Subject invention
Способ получени медно-хромокисного катализатора дл каталитического восстановлени органических соединений путем осаждени медноаммониевой соли хромовой кислоты с последующим термическим разложением последней, отличающийс тем, что медпоаммониевую соль хромовой кислоты осаждают в присутствии значительного избытка аммиака.A method for preparing a copper chromate catalyst for catalytic reduction of organic compounds by precipitating a chromic acid copper ammonium salt followed by thermal decomposition of the latter, characterized in that the chromic acid honey ammonium salt is precipitated in the presence of a significant excess of ammonia.
