The importance of copper-phyllosilicate formed in CuO/SiO₂ catalysts in the ethynylation of formaldehyde for 1,4-butynediol synthesis

Abstract

Ethynylation of formaldehyde for 1,4-butynediol synthesis catalyzed by Cu-based catalyst is an attractive technology in chemistry industry field related to 1,4-butanediol. The stabilization of Cu+ species under a reducing atmosphere...

Effective Performance of the Cu/Zn/SiO2 Catalyst Applied in the Ethynylation of Formaldehyde for 1,4-Butynediol Synthesis

“…Wang et al revealed that a small amount of ZnO can prevent the agglomeration of copper crystallites in the Cu/ZnO/SiO 2 catalyst. To further promote the activity and stability of Cu 2 C 2 , some types of supports are used in Cu-based catalysts. , Nano-SiO 2 microspheres with rich mesoporous and hydroxy groups are an appropriate choice for supporting and stabilizing Cu species. , Their application as a support effectively prevents the loss of active components of the catalyst, which greatly improves the stability of the catalyst.…”
