New pyrene-based microporous organic polymers PPOP-1, PPOP-2, and PPOP-3 have been synthesized via Friedel-Crafts alkylation reaction between pyrene and bis(1,4-dibromomethyl)benzene at their different molar ratios in the presence of a Lewis acid catalyst FeCl3 under refluxing conditions. Pore surfaces of PPOP-1, PPOP-2, and PPOP-3 have been functionalized by -SO3H groups via chlorosulfonic acid treatment under controlled reaction conditions to obtain sulfonated porous organic polymers, and these are designated as SPPOP-1, SPPOP-2, and SPPOP-3, resp. Powder X-ray diffraction, N2 sorption, HR-TEM, FE-SEM, NH3-TPD, solid state 13C CP MAS-NMR, and FT-IR spectroscopic tools are employed to characterize these materials. These sulfonated porous polymers showed nanofiber-like or spherical morphol., very high surface acidity, and excellent catalytic activity for the synthesis of biodiesels via esterification/transesterification of long chain fatty acids/esters at room temperature together with very high recycling efficiency, suggesting the future potential of these sulfonated porous polymers in a wide range of sustainable acid-catalyzed chem. reactions. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Related Products of 106-79-6).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Related Products of 106-79-6
