Green process for methacrolein separation with ionic liquids in the production of methyl methacrylate

Separation of methacrolein (MAL) is a critical technique for the production of methyl methacrylate, which is an important raw material for the preparation of acrylic resins applied in a variety of end‐uses. In this work, an azeotropic distillation process and an ionic liquid (IL) green process were developed for the separation of MAL with BmimBF₄. The two processes were simulated with Aspen plus. The simulated results are in good agreement with the experimental results which were attained in a pilot plant. Also the economic and green degree analysis of these two processes was investigated. When compared with the azeotropic distillation process, the IL green process exhibits economic superiority and green degree superiority. © 2010 American Institute of Chemical Engineers AIChE J, 2011     

植物生长调节剂对沙田柚采后伤果的贮藏防腐保鲜

沙田柚采后果实中部表面削10个约1cm^2的伤口,以多效唑、2,4-D、防落素、IAA、α-萘乙酸、β-萘氧乙酸、矮壮素、赤霉素、缩节胺、丁酰肼、青鲜素、激动素、水杨酸（sA）等PGR处理,7d后单果包聚苯乙烯薄膜。1．0mmol／L多效唑处理沙田柚伤果室温贮藏90d,绿色南方的腐果率相当,表明多效唑对沙田柚伤果的贮藏腐烂的抑制作用明显。多效唑、矮壮素、缩节胺及α-萘乙酸处理果实贮期内的呼吸强度、汁孢果汁率、可溶性固形物、Vc和果酸含量无明显差异。

滑板磨制粉泥在滑板中的利用研究

为了研究滑板磨制粉泥利用的可行性,将经过干燥和碎化处理的滑板磨制粉少量取代或全部取代常用铝锆碳滑板生产配方中的预混粉,成型后的样块经200℃24 h干燥后,分别在电炉中裸烧(500℃3 h、1 000℃3 h)和在滑板生产线的匣钵中埋炭烧成(1 300～1 450℃)。通过检测不同条件热处理后试样的显气孔率、体积密度、质量变化率、线变化率、常温耐压强度、高温抗折强度及抗水化性能发现:用少量(质量分数1.9%～5.5%)的滑板磨制干粉泥部分取代滑板生产配方中的预混粉时,对滑板的性能影响较小;用其全部取代预混粉且加入铝粉和增强抗水化剂进行基质调节时,试样的各项性能接近甚至超过滑板生产试样的。可见,滑板磨制粉泥经干燥和碎化处理后,可作为优质微细粉原料应用于滑板生产中。     

Regeneration dynamics of potassium-based sediment sorbents for CO2 capture

Simulating regeneration tests of Potassium-Based sorbents that supported by Suzhou River Channel Sediment were carried out in order to obtain parameters of regeneration reaction. Potassium-based sediment sorbents have a better morphology with the surface area of 156.73 m²·g^?1, the pore volume of 357.5×10^?3 cm³·g^?1 and the distribution of pore diameters about 2–20 nm. As a comparison, those of hexagonal potassium-based sorbents are only 2.83 m²g^?1, 7.45×10^?3 cm³g^?1 and 1.72–5.4 nm, respectively. TGA analysis shows that the optimum final temperature of regeneration is 200 and the optimum loading is about 40%, with the best heating rate of 10 °C·min^?1. By the modified Coats-Redfern integral method, the activation energy of 40% KHCO₃ sorbents is 102.43 kJ·mol^?1. The results obtained can be used as basic data for designing and operating CO₂ capture process.
