    摘要: The present invention relates to a process for the coammoximation, that is to say for the simultaneous ammoximation, of ketones, in particular of cyclic ketones such as cyclododecanone and cyclohexanone. Ammoximation is taken to mean here the preparation of oximes from ketones or aldehydes together with hydrogen peroxide and ammonia and in the presence of a catalyst which essentially consists of silicon, titanium and oxygen, for example titanium silicalite.

    摘要: The invention relates to a method for the coammoxidation, i.e. for the simultaneous ammoxidation of ketones, especially of cyclic ketones such as cyclododecanone and cyclohexanone. The ammoxidatian method of the invention relates to the production of oximes from ketones or aldehydes using hydrogen peroxide and amnmonia and further using a catalyst that substantially consists of silicon, titanium and oxygen, such as for example titanium silicalite.

    摘要: A process for oxidizing a cycloalkane, includes contacting a gas with a starting mixture, to form a product mixture, where the starting mixture contains (i) a cycloalkane, (ii) boric acid, and (iii) cobalt. The gas contains oxygen, the cycloalkane has 9 to 16 carbon atoms, and the product mixture contains a cyclic alcohol. The reactor output is increased by adding the cobalt salt, so that it is possible to lower the temperature, which decreases the rate of parallel and secondary reactions.
