optically active biobased hollow polymer particles preparation chiralization and adsorption toward chiral amines
Industrial & Engineering Chemistry Research, 2019Co-Authors: Saleem Raza, Xueyong Yong, Jianping DengAbstract:The present work reports a new type of optically active biobased hollow polymer particles (OABHPs) starting from a commonly available biophenylpropene trans-anethole (ANE). To prepare the OABHPs, ANE and maleic anhydride (MAH) underwent precipitation copolymerization in the presence of particulate template as cores, thereby forming core/shell particles. Subsequently removing the cores provided hollow particles, which were then chiralized with chiral agents (R- and S-1-phenylethylamine) and (R- and S-cyclohexyalethylamine) to fabricate the designed OABHPs. The as-prepared particles were characterized by SEM, TEM, elemental analysis, CD, and FT–IR measurements. The chiral particles’ enantioselectivity was further explored by using them as chiral adsorbent toward d- and l-alanine and (−)-cinchonidine and (+)-cinchonine. The optically active hollow particles showed good enantiomeric excess (e.e.) toward racemic alanine. The study not only opens up a new approach for preparing chiral polymer materials, but als...

thermodynamic properties and ideal gas enthalpies of formation for butyl vinyl ether 1 2 dimethoxyethane methyl glycolate bicyclo 2 2 1 hept 2 ene 5 vinylbicyclo 2 2 1 hept 2 ene trans azobenzene butyl acrylate di tert butyl ether and hexane 1 6 diol
Journal of Chemical & Engineering Data, 1996Co-Authors: W V Steele, S E Knipmeyer, Robert D. Chirico, A Nguyen, N K SmithAbstract:Ideal-gas enthalpies of formation of butyl vinyl ether, 1,2-dimethoxyethane, methyl glycolate, bicyclo[2.2.1]hept-2-ene, 5-vinylbicyclo[2.2.1]hept-2-ene, trans-azobenzene, butyl acrylate, di-tert-butyl ether, and hexane-1,6-diol are reported. Enthalpies of fusion were determined for bicyclo[2.2.1]hept-2-ene and trans-azobenzene. Two-phase (solid + vapor) or (liquid + vapor) heat capacities were determined from 300 K to the critical region or earlier decomposition temperature for each compound studied. Liquid-phase densities along the saturation line were measured for bicyclo[2.2.1]hept-2-ene. For butyl vinyl ether and 1,2-dimethoxyethane, critical temperatures and critical densities were determined from the dsc results and corresponding critical pressures derived from the fitting procedures. Fitting procedures were used to derive critical temperatures, critical pressures, and critical densities for bicyclo[2.2.1]hept-2-ene, 5-vinylbicyclo[2.2.1]hept-2-ene, trans-azobenzene, butyl acrylate, and di-tert-but...
