Abstract
The invention relates to a method for preparing cobalt carbonyl. The method is characterized by comprising employing a cobalt particle as a raw material, performing carbonylation on the cobalt particle with CO in a high-pressure synthesis kettle for generating a cobalt carbonyl gas, and condensating the cobalt carbonyl gas to form cobalt carbonyl. The method for preparing cobalt carbonyl is simple in technology and is suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of method preparing cobalt-carbonyl.
Background technology
Cobalt-carbonyl is a kind of important carbonylcomplex, is also a kind of important catalyzer.Common monokaryon cobalt-carbonyl mainly contains three kinds of form: Co
2(CO)
8, HCo (CO)
4and Na [Co (CO)
4].The catalyst activity made due to cobalt-carbonyl is high, and cost ratio Pt, Pd, Rh complex compound is cheap, therefore receives much concern.Its synthetic method is a difficult problem all the time, does not make substantial progress.
Summary of the invention
Object of the present invention develop a kind of technique simple, mass-producing can prepare the method for cobalt-carbonyl.
To achieve these goals, the present invention by the following technical solutions.
Prepare a method for cobalt-carbonyl, it is characterized in that its preparation process adopts cobalt granule to be raw material, cobalt granule and CO are carried out carbonylation at Autoclaves for synthesis and generates cobalt-carbonyl gas, then cobalt-carbonyl that cobalt-carbonyl gas cold is congealed into.
A kind of method preparing cobalt-carbonyl of the present invention, it is characterized in that its cobalt granule is cobalt powder or the shrend cobalt be made up of electrodeposited cobalt or levigate cobalt powder, its particle diameter is less than 5mm.
A kind of method preparing cobalt-carbonyl of the present invention, it is characterized in that cobalt granule is placed in Autoclaves for synthesis by preparation process, by passing into the high-purity CO being heated to 150-170 DEG C bottom synthesis reactor, control synthesis reactor pressure 20-25MPa, CO and cobalt granule carbonylation generate cobalt-carbonyl gas, and synthetic gas is discharged by synthesis reactor top, through interchanger, synthetic gas temperature are reduced to 20-25 DEG C, cobalt-carbonyl gas cold congeals into cobalt-carbonyl particle, is packaged into vial in after being collected by strainer.
A kind of method preparing cobalt-carbonyl of the present invention, employing cobalt granule is raw material, is reacted by cobalt granule, prepare cobalt-carbonyl in reactor Yu by the carbon monoxide gas of reactor, can realize suitability for industrialized production.
