The issue of measuring the refractive indices of nickel carbonyl has been addressed in only two papers. However, the purity of the samples used for measurements is not indicated in them; measurements were carried out for a small number of spectral lines and in a limited temperature range. ...

The cross section of the nickel carbonyl oxidation reaction was measured by studying the kinetics of the reaction. The amount of reacted substances was determined by the appearance of oxidation products in the reaction chamber by the optical method. As is known, the oxidation products of nickel carbonyl ...

When obtaining powdered nickel by the carbonyl method, at the intermediate stage it is necessary to monitor the degree of purification of nickel carbonyl from iron carbonyl. Currently, the content of iron carbonyl is determined by chemical analysis lasting 6‑8 hours. A faster method for monitoring the content of iron carbonyl in the product is proposed – an optical one, which can be made the basis of an automatic analyser...
