Easy, safe, and cost-effective hydroxyl-containing microporous hyper-crosslinked polymers based on phenol (pPhOH) or 4,4′-(propane-2,2-diyl)diphenol (or bisphenol A; BPA) were prepared by the Friedel-Crafts alkylation reaction of phenol and bisphenol A using dimethoxymethane as an external crosslinker. The pPhOH and pBPA were functionalized by chlorosulfonic acid to yield corresponding sulfonic acid-functionalized polymers, pPh-SO3H and pBPA-SO3H, resp., with their surface areas of 210 m2/g and 324 m2/g, resp. The physicochem. properties of pPh-SO3H and pBPA-SO3H were analyzed by Fourier transform IR spectroscopy, X-ray diffraction, thermogravimetric anal., SEM, Brunauer-Emmett-Teller anal., and XPS. The pPh-SO3H and pBPA-SO3H polymers show excellent catalytic activity for the esterification of free fatty acids and transesterification of vegetable oils at room temperature, as well as excellent recyclability, signifying the potential of these porous polymers in a wide array of eco-friendly acid-promoted chem. transformations. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Safety of Dimethyl decanedioate).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Safety of Dimethyl decanedioate
