Ni-loaded Catalyst Containing Activated Clay for Maleic anhydride Hydrogenation to succinic anhydride

引用

China Petroleum Processing & Petrochemical Technology 2011年第4期13卷 35-40页

作者： Tian Weiping Guo Shaofei Shi Li (The State Key Laboratory of Chemical Engineering, East China University of Science and Technology, Shanghai 200237) E China Univ Sci & Technol State Key Lab Chem Engn Shanghai 200237 Peoples R China

In this work, the hydrogenation of maleic anhydride to succinic anhydride in the presence of 5 m%Ni/clay catalysts was investigated. These catalysts were characterized by X-ray diffraction （XRD）, H2 temperature programmed reduction （TPR） and thermogravimetric analysis （TGA） techniques. The XRD and TPR studies showed that Ni was present as Ni2＋ on the support, which indicated that there were no elemental nickel （Ni^0） and Ni203 species in the unreduced samples. Increasing of calcination temperature to 650 ℃ leads to destruction of the support structure observed in TGA, while the catalyst sample calcined at 550 ℃ exhibits better performances than other samples. The ideal conversion of maleic anhydride （97.14%） and selectivity of succinic anhydride （99.55%） were realized at a reaction temperature of 180 ℃ and a weight hourly space velocity of 4 h^-1 under a reaction pressure of 1 MPa.

The aim of this work was to use cellulose nanocrystals that were obtained by hydrolysis in phosphoric acid solution and further modified with succinic anhydride in the microwave field for PLA reinforcement.A series of allbionanocomposites containing unmodified and surface modified cellulose nanocrystals with CNC content in the range of 1–3%_(w.t.) were obtained by melt blending and tested by XRD,SEM,DSC and DMA to investigate the effect of surface esterification of CNCs on the structure,morphology,dynamic mechanical properties of bionanocomposites,as well as phase transitions of PLA in the presence of cellulosic *** investigations showed the highest increase of storage modulus by ca.7%(335 MPa at 25℃)in the glassy state of PLA for 2%_(w.t.)of unmodified ***,addition of 2%_(w.t.)of succinylated CNCs caused the highest increase of the onset of glass transition temperature(by 6.2℃)thus widening the temperature range of biocomposite *** increase of glass transition temperature indicates the strongest interfacial interactions due to improved miscibility of surface modified nanocrystals and thus good dispersion of additive in PLA matrix providing high interface.

Ring opening copolymerization of succinic anhydride (SA) with ethylene oxide (EO)was successfully carried out by using a series of aluminum-based catalyst in 1,4-dioxane at62±2℃. The results showed that in-situ AlR_3-H_2O (R=ethyl, iso-butyl) catalysts gavehigher molecular weight (M_w～10~4), while Al(OR)_3 catalysts gave the higher alternatingcopolymer structure with slightly lower molecular weight. The in-situ AlR_3-H_2O systemshave been evaluated in more detail for the reaction which showed the optimum H_2O/Almolar ratio to be 0.5. The copolymers with different composition (F_(SA)/F_(EO)= 36/64to 45/55 mol/mol) were synthesized by using different monomer feed ratio. The melt-ing point (T_m), glass transition temperature (T_g) and enthalpy of fusion (ΔH_f) of thesecopolymers are depended on the copolymer composition and in the range of 87～102℃,-12～-18℃, and 37～66J/g, respectively. The second heating scan of DSC also in-dicated that the higher alternating copolymer was more easily recrystallized. The onsetdecomposition temperature was more than 300℃ under nitrogen and influenced by thecopolymer composition.

Ni/Al_2O_3 catalysts derived from spinel NiAl_2O_4 for low-temperature hydrogenation of maleic anhydride to succinic anhydride

引用

Chinese Journal of Catalysis 2017年第7期38卷 1166-1173页

作者：李杰任远航岳斌贺鹤勇复旦大学化学系上海市分子催化与功能材料重点实验室上海200433

Ni/Al2O3 catalysts were derived from spinel NiAl2O4 with different Ni content ((2.5, 5 and 7.5) wt%). The catalysts were obtained by H-2 reduction and were investigated for the low-temperature hydrogenation of maleic anhydride (MA) to produce succinic anhydride (SA). The characterization results showed that Ni-0 active sites were mainly derived during the H2 reduction from spinel NiAl2O4 Among the catalysts studied, employing the optimum preparation and reaction conditions with Ni(5%)/Al2O3 yielded the highest catalytic performance. A near-100% conversion of MA and similar to 90% selectivity to SA were achieved at 120 degrees C and 0.5 MPa of H-2 with a weighted hourly space velocity (MA) of 2 h(-1).

Preparation of Starch Succinate WITH INTERMEDIATE DS BY AQUEOUS SLURRY REACTION

引用

Chinese Journal of Reactive Polymers 2001年第2期10卷 179-185页

作者： ZHU Changying WANG Bin ZHAO Fukai CAO Yurong WANG Linfu XU Jiayi Department of Chemistry NanKai University Tianjin 300071 China

The succinylation of cornstarch by slurry reaction has been studied using sodium hydroxide as catalyst. Several reaction parameters affecting the succinylation were investigated including the concentration of starch in water, the ratio of succinic anhydride to starch, the reaction time and the reaction temperature. The favorable conditions for an intermediate degree of substitution (DS) and reasonably high reaction efficiency (RE) are pH 8.5~9.0, 50% starch by weight to water, succinic anhydride to starch 1/1 (w/w), reaction time 4h, reaction temperature 30℃. Under these conditions, the DS of 0.45 and RE of 28% were achieved. The addition of an adequate amount of crosslinking agent imparted starch succinate water absorbency.
