The deca- Nord manufacturing method which is due to the hydrogenation of decenal

摘要

As for this invention, in regard to the method in order to produce at least one deca- Nord, at least with the hydrogenation of one decenal, at that time, as for 1st hydrogenation, in the liquid phase it is done with the solid 1st catalyst, in this case the 1st catalyst contains the copper and the nickel. It is something which is based on the topic that it states the method of the superordinate concept where this invention, after the long operating time, at high yield hydrogenates decenal to deca- Nord, is stated in the beginning. Especially, content of the unreacted decenal in hydrogenation carrying out ones is proper under 1500ppm. This topic does hydrogenation at two stages, namely with 1st process itself with known method, the chrome and/or does with the catalyst which contains barium oxide with the copper, the nickel and case, follows to that and with 2nd process, it must be copper non- containing, chrome non- containing and nickel non- containing, it is solved by doing with another catalyst.
