Acetylene on Si(100) from first principles: adsorption geometries, equilibrium coverages and thermal decomposition [PDF]
, 2000 Adsorption of acetylene on Si(100) is studied from first principles. We find that, among a number of possible adsorption configurations, the lowest-energy structure is a ``bridge'' configuration, where the C$_2$H$_2$ molecule is bonded to two Si atoms ...

Dynamic optimization of acetylene hydrogenation reactors with considering catalyst deactivation [PDF]
مجله مدل سازی در مهندسی, 2022 Ethylene is a very important material in petrochemical industries, whose chief application is producing polymers. The steam cracking of naphtha or ethane is usually applied to produce ethylene. A small amount of acetylene is produced in this process. The

Influence of acetylene on methane–air explosion characteristics in a confined chamber
Scientific Reports, 2021 To study the impact of acetylene on methane explosions, the safe operation of coal mines should be ensured. In this paper, a 20 L spherical tank was used to study the explosive characteristics of acetylene–methane–air mixture.

Diverse synthesis of C2-linked functionalized molecules via molecular glue strategy with acetylene
Nature Communications, 2022 Although acetylene is an ideal two-carbon building block, very few catalytic methods can be applied to incorporate acetylene into fine chemicals. Here, the authors show photoredox-catalyzed syntheses of C2- linked molecules with gaseous acetylene under ...
