N1 - Experiments on synthesis and examination of the properties of carbon nanomaterials were supported financially by the Ministry of Science and Higher Education of the Russian Federation (project 075-15-2020-797 (13.1902.21.0024)).

N2 - The pyrolysis of acetylene was studied experimentally in a cyclic compression reactor in an atmosphere of buffer inert gases (argon, neon, helium). A significant difference in the thermodynamic conditions for the complete pyrolysis of the precursor for various buffer gases was revealed. The reaction products of acetylene in neon and helium contained up to 20% of the part soluble in organic solvents. The study of the ethanol-soluble part of the product using time-of-flight mass spectrometry with matrix-assisted laser desorption/ionization made it possible to distinguish even and odd branches in the spectrum of substances by the number of carbon atoms. A mechanism is proposed for the formation of larger particles by merging smaller ones. Keywords: cyclic compression reactor, acetylene pyrolysis, buffer inert gas, growth mechanism, carbon nanoparticles.
