Pore volume accessibility of particulate and monolithic stationary phases was written by Urban, Jiri. And the article was included in Journal of Chromatography A in 2015.COA of Formula: C16H26O7 This article mentions the following:
A chromatog. characterization of pore volume accessibility for both particulate and monolithic stationary phases is presented. Size-exclusion calibration curves were used to determine the pore volume fraction that is accessible for six alkylbenzenes and twelve polystyrene standards in THF as the mobile phase. Accessible porosity was then correlated with the size of the pores from which individual compounds are just excluded. The author has determined pore volume accessibility of com. available columns packed with fully and superficially porous particles, as well as with silica-based monolithic stationary phase. The author also has studied pore accessibility of polymer-based monolithic stationary phases. Suggested protocol was used to characterize pore formation at the early stage of the polymerization, to evaluate an extent of hypercrosslinking during modification of pore surface, and to characterize the pore accessibility of monolithic stationary phases hypercrosslinked after an early termination of polymerization reaction. Pore volume accessibility was also correlated to column efficiency of both particulate and monolithic stationary phases. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1COA of Formula: C16H26O7).
((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.COA of Formula: C16H26O7
