Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1977-07-7, Name is 11-(4-Methylpiperazin-1-yl)-5H-dibenzo[b,e][1,4]diazepine, molecular formula is C18H20N4, belongs to pyrrolines compound, is a common compound. In a patnet, author is Alavinia, Sedigheh, once mentioned the new application about 1977-07-7, Safety of 11-(4-Methylpiperazin-1-yl)-5H-dibenzo[b,e][1,4]diazepine.
Targeted development of hydrophilic porous polysulfonamide gels with catalytic activity
We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Brunsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydmgels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1977-07-7. The above is the message from the blog manager. Safety of 11-(4-Methylpiperazin-1-yl)-5H-dibenzo[b,e][1,4]diazepine.
