Organosilicon compounds in supercritical carbon dioxide: Synthesis, polymerization, modification, and production of new materials

Organosilicone Compounds in Supercritical Carbon Dioxide

“…At present, supercritical CO 2 has a wide range of applications. A large number of works have been devoted to the synthesis of various polymer particles in supercritical fluids, including CO 2 [2], the creation of composites based on compounds soluble in CO 2 and insoluble substrates [3], the modification of polymers, the synthesis of catalysts, polymerization, and polycondensation [4,5]. One more significant field is organosilicon polymers, which, along with fluoropolymers, form two large classes of macromolecular compounds soluble in scCO 2 [6,7].…”

“…We focused on the results of (co)polymerization in scCO 2 , the advantages of using organosilicon compounds as polymerization stabilizers, and the development of approaches to coating from carbon dioxide. In this review, the authors tried to supplement the previous review on related topics published in 2016, where the role of supercritical carbon dioxide in various chemical processes both as a solvent and a reagent was analyzed [5]. In the present review, we focus on recently published articles as well as those not previously reviewed in Ref.…”

A Versatile Equilibrium Method for the Synthesis of High-Strength, Ladder-like Polyphenylsilsesquioxanes with Finely Tunable Molecular Parameters

“…In recent decades, there has been a growing interest in compressed gas media as new solvents for chemical reactions, including condensed gases and supercritical fluids [26][27][28][29]. The main advantages of these media include the possibility of adjusting their dissolving capacity and their instant removal from the reaction media.…”

Mechanism on The Disproportionating Synthesis of Dichlorodimethyl‐ silane by ZSM‐5(5 T)@γ‐Al2O3 Series Core‐Shell Catalysts

“…With the continuous growth of the number and variety of organic silicon, the application market has been continuously expanded to form an important product system unique to the chemical new materials industry, and demand for them is likewise increasing. In the silicone industry chain, monomers play a vital role, which preparation level marks the development level of the silicone industry . The amount of methylchlorosilanes accounts for more than 90% of the total monomers' yield, in which dimethyldichlorosilane((CH 3 ) 2 SiCl 2 , abbreviated as M2) is the most used and most important one .…”
