In 2022,Tandekar, Kesar; Tripathi, Anjali; Prasad, Muvva D.; Supriya, Sabbani published an article in Materials Advances. The title of the article was 《Keggin based self-assembled mesoporous materials for capture of selective guest molecules》.Quality Control of Ethyltriphenylphosphonium bromide The author mentioned the following in the article:
A series of self-assembled mesoporous materials, compounds 1-9, of the type [RPPh3]n[XM12O40] (R = Ph, Me, Et; n = 3 or 4; X = P, Si; M = Mo, W) composed of Keggin anions and phosphonium cations have been fabricated and characterized. These thermally stable hybrid materials show selective reversible uptake of non-polar mols. such as iodine and carbon disulfide under ambient conditions. The resultant porosity is attributed to the self-assembling of the cations on the surface of the Keggin anion such that the pores are lined with the phosphonium cations rendering them hydrophobhic. The present work explores the spontaneous self-assembly process of POM integrated mesoporous compounds stabilized via non-covalent interactions and their potential applications as adsorbing materials. In the experimental materials used by the author, we found Ethyltriphenylphosphonium bromide(cas: 1530-32-1Quality Control of Ethyltriphenylphosphonium bromide)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. CatOnium ETPB is also used as catalysts in the synthesis of certain organic compounds.Quality Control of Ethyltriphenylphosphonium bromide
