• Description: Sodium acetylide is an unstable powder, a salt of acetylene. It is a severe explosion risk when shocked or heated. It is used in the manufacture of detonators.
• Uses: Sodium acetylide suspension has been used in the preparation of: 2-ethynyladamantan-2-ol1 apical-equatorial (ae) isomer of (Et4N)3[1-(2′-B10H9)-2-NH3B10H8]2 trimethylsilylacetylene3 Sodium Acetylide Suspension is a reagent used in the synthesis of rhodium(I) amidinate complexes.

Technology Process of Sodium acetylide

There total 11 articles about Sodium acetylide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

N,N-dichloroethylamine (24948-83-2) + sodium (7440-23-5) → sodium acetylide (115570-70-2,1066-26-8) + sodium chloride (7647-14-5)

Guidance literature:

In xylene; byproducts: N2, C2H2; vigorous reaction of crushed Na with ethyldichloramine at 80-100°C; evolution of N2, C2H2, saturated hydrocarbons; mixture of NaCl and C2NaH remained;;

Reference yield:

acetylene (74-86-2,25067-58-7) → sodium acetylide (1066-26-8)

Guidance literature:

With sodium; xylene; at 60 - 110 ℃;

DOI:10.1021/jo01357a016

Reference yield:
