A detailed theoretical investigation for the ion−molecule reaction of HCN + with C 2 H 2 is performed at the B3LYP/6-311G(d,p) and CCSD(T)/6-311++G(3df,2pd) (single-point) levels. Possible energetically allowed reaction pathways leading to various low-lying dissociation products are probed.

C2H2 + HCN = CH2CHCN is a Synthesis reaction where one mole of Acetylene [C 2 H 2] and one mole of Hydrogen Cyanide [HCN] combine to form one mole of Acrylonitrile [CH 2 CHCN]

2021年3月1日 · Implications for extraterrestrial hydrocarbon chemistry: analysis of acetylene (C2H2) and D2-acetylene (C2D2) ices exposed to ionizing radiation via ultraviolet-visible spectroscopy, infrared spectroscopy, and reflectron time-of-flight mass spectrometry

2025年2月19日 · The detection of HCN suggests intense vertical mixing ($K_{zz}\sim10^{11}$cm$^2$s$^{-1}$), challenging previous literature derivations of $K_{zz}$ values for T-type brown dwarfs. Even more surprising is the C2H2 detection, which cannot be explained with existing atmospheric models for isolated objects.

2024年2月1日 · To address this gap, we present a detailed C2-CN sub-mechanism integrated into a NOx and polycyclic aromatic hydrocarbons (PAHs) kinetic model. The rate constants of the barrierless association reactions of C2 H+CN, C 2 H 3 +CN, C 2 H 5 +CN, and CH 3 +CH 2CN were updated using the variable reaction coordinate transition state theory (VRC-TST).

2008年9月4日 · A detailed theoretical investigation for the ion-molecule reaction of HCN (+) with C 2H 2 is performed at the B3LYP/6-311G (d,p) and CCSD (T)/6-311++G (3df,2pd) (single-point) levels. Possible energetically allowed reaction pathways leading to various low-lying dissociation products are probed.

Chủ đề c2h2+hcn: Phản ứng giữa C2H2 và HCN là một quá trình hóa học quan trọng, mang lại nhiều ứng dụng trong công nghiệp và nghiên cứu. Trong bài viết này, chúng ta sẽ khám phá chi tiết về cơ chế, sản phẩm, và tác động của phản ứng …

C2H2 + HCN = C5H5N is a Synthesis reaction where two moles of Acetylene [C 2 H 2] and one mole of Hydrogen Cyanide [HCN] combine to form one mole of Pyridine [C 5 H 5 N]

1989年12月1日 · For both isomers the acetylenic and hydrogen cyanide C-H stretch vibrational bands have been recorded. The results clearly show that the predissociation lifetimes of these isomers depend strongly upon whether or not the C-H vibration excited is in- volved directly in the formation of the hydrogen bond.

2012年8月11日 · c2h2+hcn=ch2=chcn 关于炔烃的亲核加成的机理，通常解释为sp杂化轨道的电子云过于密集，不能充分覆盖C 原子核 ，使亲核试剂可以进攻C原子核，从而发生亲核加成反应。
