determination and correlation of solubilities for succinic acid in the adipic acid glutaric acid Acetone Mixture and adipic acid in the succinic acid glutaric acid Acetone Mixture
Journal of Chemical & Engineering Data, 2016Co-Authors: Fei Wang, Zhuoyuan Ning, Chunhua Jiang, Xunqiu WangAbstract:To provide fundamental thermodynamic data for the crystallization separation of succinic acid and adipic acid from mixed dibasic acid, the solubilities of succinic acid in various mass fractions of the adipic acid + glutaric acid + Acetone Mixture and adipic acid in various mass fractions of the succinic acid + glutaric acid + Acetone Mixture were measured by the dynamic method at a temperature range of 277.85–327.95 K under atmospheric pressure. The results showed that the solubility of succinic acid in Acetone increased with increasing mass fraction of adipic acid and glutaric acid in the mixed solvent at the same temperature. Similarly, the solubility of adipic acid in Acetone increased with increasing mass fraction of succinic acid and glutaric acid in the mixed solvent at the same temperature. The ideal solution equation, Apelblat equation, λh equation, and nonrandom two-liquid (NRTL) equation were applied to correlate the experimental solubility data, which were all in good agreement with the four e...

solubilities of adipic acid and succinic acid in a glutaric acid Acetone or n butanol Mixture
Journal of Chemical & Engineering Data, 2014Co-Authors: Yatao Wang, Zhuoyuan Ning, Jianfang Cui, Xunqiu WangAbstract:In order to provide thermodynamic data for mixed dibasic acid separation technology, the solubilities of adipic acid (AA) and succinic acid (SA) in glutaric acid (GA) + Acetone Mixture and GA + n-butanol Mixture were measured by dynamic method at atmospheric pressure. The mass fraction of GA (wGA) ranged from (0 to 30.11) %. The results show that solubilities of AA and SA in Acetone or n-butanol increased with increasing mass fraction of GA in the mixed solvent GA and Acetone (or n-butanol) at the same temperature. The ideal solution equation, Apelblat equation, and λh equation were applied to correlation of the experimental solubility data, which were all in good agreement with the three equations. The Apelblat equation is regarded as the best one of the three equations for describing the dissolving of two acids in solvent at the same time.

structural features of liquefaction residue from shenmu fugu subbituminous coal
Fuel, 2019Co-Authors: Zhi-min Zong, Xian-yong Wei, Yugao Wang, Guixia FanAbstract:Abstract Liquefaction residue (LRSFSBC) from Shenmu-Fugu subbituminous coal was ultrasonically extracted with petroleum ether, methanol, cyclohexane, ethyl acetate, Acetone, carbon disulfide (CDS) and isometric CDS/Acetone Mixture (IMCDSAM), respectively. A number of alkanes, arenes, arenols, alkanols, alkenones, esters, and nitrogen-containing organic compounds were identified according to the analyses with Fourier transform infrared spectrometer, gas chromatograph/mass spectrometer, direct analysis in real-time ionization source coupled with ion trap mass spectrometer, and solid-state 13C nuclear magnetic resonance (SS 13C NMR). The tetra- and penta-substituted anthracene or phenanthrene unit could be the average structures in LRSFSBC by SS 13C NMR analysis. The main intermolecular interactions among the organic species in LRSFSBC are π–hydrogen bonds and π–π interactions. These interactions are also the cause for “capsule” formation. Stronger interactions between LRSFSBC and solvents, especially CDS and IMCDSAM, destroyed the interactions and thereby led to high extract yields.

sequential extraction and characterization of liquefaction residue from shenmu fugu subbituminous coal
Fuel Processing Technology, 2015Co-Authors: Zhi-min Zong, Xian-yong Wei, Yun-peng Zhao, Xing Fan, Fang-jing Liu, Yugao Wang, Wei ZhaoAbstract:Abstract Liquefaction residue from Shenmu–Fugu subbituminous coal (LR SFSBC ) was fractionated into extracts 1–6 (E 1 –E 6 ) and inextractable portion (IEP) by sequential extraction with petroleum ether, cyclohexane, methanol, Acetone, carbon disulfide (CDS), and isometric CDS and Acetone Mixture (ICDSAM) followed by analyses with Fourier transform infrared (FTIR) spectrometer, gas chromatography/mass spectrometer (GC/MS) and atmospheric solid analysis probe/time of flight mass spectrometer (ASAP/TOF-MS). In total, 69.06% of LR SFSBC were extracted by the sequential extraction. Large amounts of multi-substituted alkylarenes and hydroarenes were identified in LR SFSBC according to GC/MS and FTIR analyses. A series of nitrogen heterocyclic aromatics and arylamines in LR SFSBC were enriched in E 3 . In total 61 compounds were detected with GC/MS, including 48 arenes with a total relative content of 98.72%, while 478 organooxygens, organonitrogens, organosulfurs, and organochlorines were detected with ASAP/TOF-MS. The double bond equivalent, carbon number, and molecular mass distribution of the compounds range from 0 to 13, 6 to 23, and 230 to 511 Da, respectively, by ASAP/TOF-MS analysis. E 1 with the yield of 33.47% could be converted to light oil by catalytic hydroconversion due to its high H/C ratio and low sulfur content, while E 5 could be a promising precursor for preparing carbon materials because of its high carbon content and C/H ratio.
