Abstract:α-Hydroxyl fatty acids (α-HFA) were hydrothermally synthesized through neutral hydrolysis of α-chloro fatty acids (α-CFA) derived directly from natural fatty acids, which is a novel green route to synthesize α-HFA from natural fatty acids with the characteristics of high yield, low-cost and environmental-friendly. In this paper, the structure of α-HFA was identified by FTIR and GC-MS and the relative molecular weight was confirmed by ESI-MS. The purity of purified α-HFA as 99% was examined by GC. Moreover, the influence of mass ratios, water dosages, reaction temperatures and reaction time on the hydrothermal synthesis has been studied. The results indicate that the yield of α-hydroxyl natural fatty acid (C12~C18) can reach 98%~99% under the following conditions: n(CaCO3) : n(α-CFA) = 1.05 : 1; m(H2O) : m(α-CFA) = 2 : 1 at 155 oC for 4 hours.

Abstract:Functional molecules of 5,10,15,20-tetraphenyl porphyrin manganese (MnTPP) and 5,10,15,20-tetraphenyl porphyrin indium (InTPP) were aggregated to be nano-materials in the water/ dimethylsulfoxide (DMSO) mixed solution by using mixed-solvents approach. UV-Vis method was used in this study, nano-dispersion systems were applied to detect dimethylmethylphosphonate (DMMP), which used to be simulant of sarin agent. Detection limits of MnTPP and InTPP to DMMP were 10-9 and 10-10 L/L respectively. Two reaction models between porphyrins and DMMP were constructed and optimized by using Density Functional Theory (DFT). The results indicated the sensing property to DMMP of InTPP was superior. This was consistent with detection results of UV-Vis technology.

The melting point and fusion enthalpy of the microcapsules are 43.7℃ and 84.96J•g-1, respectively, which mean the microcapsules possess a good potential as a latent heat storage material in latent heat thermal storage applications.

Abstract:In this paper, carboxymethylcellulose sodium/poly(acriylic acid)/attapulgite superabsorbent composites were prepared by aqueous solution polymerization using N,N’ –methylenebisacrylamide as crosslinker and ammonium persulfate as an initiator in the presence of different purity of attapulgite. The effect of the purity of attapulgite on water absorbency, water absorption rate and swelling properties in different pH medium were studied. FTIR spectra proved acriylic acid monomers were grafted onto the carboxymethylcellulose sodium backbone, and attapulgite participated in polymerization through its active silanol groups. FESEM observation showed that attapulgite fibrils led to a better dispersion in the polymeric matrix and formed a surface porous structure. More Ca2+ and Mg2+ in attapulgite are helpful to improve the swelling behaviors of the superabsorbent composites under the same content of attapulgite.

Abstract:Preferential oxidation of CO is an efficient method to remove the small amount of CO from reformed gas. The catalytic performances of different K/Pt molar ratio catalyst coatings in the preferential oxidation of CO in hydrogen rich stream were studied. The results showed that the optimal K/Pt molar ratio is about 1~1.5. When the K amount exceeded this value, the CO conversion decreased significantly. The increase in inlet O2 concentration from 1% to 1.5% can increase the CO conversion and decrease the CO2 selectivity. In addition, the effects of H2O and CO2 were also investigated. The best catalyst coating exhibited a good H2O and CO2 resistance under the best catalytic reaction temperature. The good stability during a continuous test of 100 h indicates high potential of this catalyst coating in commercial preferential oxidation of CO.
