- A macro analytic method for coal tar derived from pyrolysis at different temperatures
Qihang Liu, Xiaoming Li and Keng Wu
Version of Record online: 19 JAN 2017 | DOI: 10.1002/jccs.201600734
An experimental investigation aimed at studying kinetics of tar evolution during coal pyrolysis was reported. Pyrolysis tests were conducted on a specially designed laboratory-scale apparatus which allowed continuous monitoring and recording the tar yield. The fitting result illustrates that the established hybrid dynamic model was effective for the prediction of tar yield. Furthermore, shrinking core model, multi-particle's first order reaction and Anti-Jander diffusion equation were respectively built to elucidate the macro releasing mechanisms of coal tar.
- Sulfamic Acid-functionalized Nano-titanium dioxide as a Novel and Highly Efficient Heterogeneous Nanocatalyst for One-pot and Solvent-free Synthesis of Hexahydroquinolines
Elham Tabrizian and Ali Amoozadeh
Version of Record online: 18 JAN 2017 | DOI: 10.1002/jccs.201600802
Hexahydroquinolines are synthesized via one-pot, four-component condensation of 1,3-cyclic diketones, aromatic aldehydes, malononitrile, and ammonium acetate in the presence of sulfamic acid-functionalized nano-titanium dioxide as a novel type of heterogeneous nanocatalyst. The reaction condition is optimized using the response surface method (Box–Behnken design [BBD]). The nanocatalyst can be recovered easily by centrifugation and reused for at least seven consecutive runs.

- Synthesis of Highly Dispersed Fe3O4 Submicrometer Spheres in a One-Pot Anion-induced Solvothermal System
Peng Huang, Ting Yin, Qian Zhang, Guo Gao, Joseph G. Shapter, Cameron J. Shearer, Chunlei Zhang, Wen Qi and Daxiang Cui
Version of Record online: 12 JAN 2017 | DOI: 10.1002/jccs.201600833
Magnetic Fe3O4 submicrometer spheres are widely used for coatings, as drug and gene carriers, for catalytic treatment, and as anode materials for lithium ion batteries. Two kinds of highly dispersed magnetic Fe3O4 submicrometer spheres (~500 and ~200 nm) have been successfully synthesized via a facile anion-induced, one-pot solvothermal method. The formation mechanism relies on Ostwald ripening.
- New Substituted 1-Aryl-4,4,6-Trimethyl-3,4-Dihydropyrimidine-2-(1H)Thiones; A Metal-Free and Solvent-Free Synthesis, Characterization, and Lymphoid Tyrosine Phosphatase Inhibition Studies
Asma Khurshid and Aamer Saeed
Version of Record online: 12 JAN 2017 | DOI: 10.1002/jccs.201600805
A green synthesis of 3,4-dihydropyrimidine-2-thiones has been achieved. The series of newly synthesized compounds were tested for the lymphoid tyrosine phosphatase PTPN22 inhibition, the most potent hit being the compound 3d, having a methoxy substituent at the 2-position of the phenyl ring with an IC50 = 18.1±1 μM, and second most potent compound 3c with an IC50 value of 45.3 ± 3 μM, had methyl substituents at both 2- and 4-position of the phenyl ring.
