利福平菌丝体厌氧生化处理的研究

制药厂生产利福平过程中产生大量的利福平菌丝体,可严重污染环境。用厌氧消化法处理利福平菌丝体,消化温度40℃,反应器容积负荷2KgCOD/m~3·d,液料滞留期(SRT)14～20天,取得了良好的处理效果。COD去除率稳定在90％左右,BOD_5去除率达到95％以上,产气率达到0.49m~3/去除KgCOD。     

THE INFLUENCE OF SPINNING CONDITION ON STRUCTURE & PROPERTIES OF MASS-DYED SUPERFINE PP AS-SPUN FILAMENTS

The effect of colorant additive on the rheology of PP polymer melt and the influence of spinning conditions on the crystalline and orientation structure of mass-dyed as-spun PP filament are reported. The △E~~~ value for all colored chips is higher than that of blank chip to a varying degree. The crystallinity and orientation degree of dyed PP as-spun filament decrease with increasing melt temperature, decreasing spinning speed and increasing denier per filament (dpf), while the crystallinity of dyed as-spun filament increases with the content of colorant additive as a nucleation agent.

SIMULTANEOUS REACTION AND LIQUID-LIQUID EXTRACTION IN THE HYDROGEN PEROXIDE PRODUCTION

The gas-liquid-liquid reactive extraction system for preparing hydrogen peroxide via anthraquinone was investigated. The oxidation reaction of hydrogenated working solution was combined with the extraction of hydrogen peroxide from working solution in a sieve plate column. The reaction of 2-ethylanthrahydroquionone with oxygen and the liquid-liquid extraction of hydrogen peroxide take place simultaneously. The oxygen was introduced with hydrogenated working solution through a nozzle in the bottom of the column, which worked as agitated air as well as oxidation reagent. The results showed the oxidation and extraction do not hamper each other, on the contrary, the presence of oxidation gas in the column can promote the transfer of hydrogen peroxide from organic phase to aqueous phase, thus the reaction efficiency and extraction efficiency increased with increasing gas superficial velocity. Furthermore, the oxidation efficiency is almost 100% and the extraction efficiency is higher than 90% in this process.

以4,4''''-二(咪唑基亚甲基)联苯为客体的环糊精类轮烷的合成与表征

以4,4'-二(咪唑基亚甲基)联苯(bibp)为客体,通过自组装合成了4,4'-二(咪唑基亚甲基)联苯和环糊精的[3]类轮烷,并通过元素分析,1HNMR,ESI-MS,IR,TG-DSC进行了表征和固体热稳定性等研究,结果表明:由于bibp客体分子链较长,含有两个苯环,所以可穿入两个β-环糊精分子,形成[3]类轮烷.     

财务报表的时间性特征及其对财务分析的影响

财务报表中的各种指标按所反映的企业资金运动的时间状况，可分为反映企业资金运动在某一时刻状况的指标和反映企业资金运动在某一时期内发展变化结果的指标两大类：充分认识财务报表指标的时间性特征，有利于人们了解它对财务分析的影响。从而正确计算和运用某些财务分析指标。
