Embodiment
[0018] as attached figure 1 Shown:
[0019] The invention provides a passivation coating Raney nickel production process, comprising the following steps:
[0020] 1) Raw material addition: ① Raney nickel alloy raw materials are added to the passivation reactor equipped with a cooling system, and cooling liquid is added to the passivation reactor at the same time; ② Sodium hypochlorite is added to the buffer tank and passed through the pipeline Input into the passivation reactor; ③, tap water is added into the reverse osmosis pure water machine, and the purified water is also input into the passivation reactor through the pipeline;
[0021] 2), passivation coating treatment: the Raney nickel alloy raw material after the passivation reactor treatment in the step 1) is input in the Raney nickel passivation coating separator, carries out the passivation coating treatment, and in the step 1) after the reaction The purified water purified by the osmotic pure water machine is also ...

The invention provides a production process of passivation coating Raney nickel, relates to the technical field of Raney nickel, and solves the problem that traditional Raney nickel can spontaneously ignite when being in contact with air and must be transported and produced after being sealed and stored with water. The passivation coating Raney nickel production process comprises the following steps: 1) raw material addition: (1) adding a Raney nickel alloy raw material into a passivation reactor provided with a cooling system, and adding a cooling liquid into the passivation reactor at the same time. The raney nickel alloy raw material is subjected to passivation reaction and passivation coating treatment during production to obtain the passivation coated raney nickel, and the defect that the traditional raney nickel can spontaneously ignite when being in contact with air and must be transported and produced after being sealed with water is overcome. The obtained passivation coated raney nickel is not spontaneously ignited when being in contact with air, is not combusted, does not need to be sealed with water, is safe and reliable in transportation and use processes, is insensitive to toxicants, and can better meet application requirements compared with traditional Raney nickel.
Description
technical field [0001] The invention belongs to the technical field of Raney nickel, and more specifically relates to a passivation coating Raney nickel production process. Background technique [0002] Raney nickel, also translated as Raney nickel, is a solid-state heterogeneous catalyst composed of fine grains of nickel-aluminum alloy with a porous structure. Usually used as a hydrogenation catalyst for organic compounds, it can be used in hydrogenation reduction reactions of compounds containing unsaturated bonds such as aldehydes and ketones. [0003] Traditional Raney nickel can spontaneously ignite when in contact with air and must be stored in water. It is easy to spontaneously ignite and burn when in contact with air, and it is easy to cause safety accidents during transportation and production. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a passivation coating Raney nickel production process to ...
