objective to determine the contents of residual acetone in acetoacetic ester,the raw material for the synthesis of edaravone, by gas chromatography.methods sample solution was injected on a gdx column (0.18 mm~0.25 mm) with nitrogen as the carrier gas.the residue was calculated by the external standard method.results the linearity was good over the range of 25 μg/ml~400 μg/ml,with the correlation coefficient of acetone being 0.996 and the average recovery 96.8%.conclusions the method was proved to be simple,rapid,practical and highly sensitive.it is an efficient method for the quality control of acetoacetic ester.
摘要] 目的:用气相色谱法测定依达拉奉合成起始原料乙酰乙酸乙酯中丙酮的残留量。方法:采用固定相为二乙烯苯乙基乙烯苯型高分子多孔小球(直径为0.18 mm~0.25 mm),氮气为载气,用外标法测定乙酰乙酸乙酯中残留丙酮的含量。结果:该方法在丙酮浓度范围在25 μg/ml~400 μg/ml内呈良好的线性关系,响应曲线相关系数为0.996,平均回收率为96.8%。结论:本法简便,快速、实用,灵敏度高,可有效地用于乙酰乙酸乙酯的质量控制。

The concentrations of CODcr and NH4+ vary from low to high, then from high to low in the process of refuse leaching, that is to say that there are three phases which are aerobian decomposition, facultative aerobian and anaerobian decomposition;(3)The time of landfill reaching to stabilize under the condition of filtration, for landfill of Jinqianpu, is at least 86 years if CODcr is regarded as a index; but is about 98 years when NH4+ as an index;(4)The column leaching experiment simulated is carried on interactivity between leachate and different lithologic characters, water-bearing media of different thickness. Some parameters can be determined by calculation, such as, the retained factor and hydro-chemical transportation rate of pollutants in suspended media, which quantitatively analyse the suspended soil capability of components purification and the pollution scope of water bearing media.
垃圾淋滤过程中和经历了一个由低到高、再由高到低的过程,即垃圾填埋过程中经历了好氧分解、兼性好氧分解及完全厌氧分解等三个阶段;(3)垃圾组分在淋滤条件下分解达到稳定的时间,对于金钱堡垃圾填埋场,若以作为考核指标,填埋场达到稳定化时间至少需要86年;若以作为考核指标,则填埋场达到稳定化至少需98年的时间;(4)对垃圾浸泡液与不同岩性、不同厚度含水层介质之间的作用进行了土柱淋滤模拟试验,通过计算污染质在包气带介质中运移的阻滞因子和水化学迁移率等参数,定量地描述了包气带土层对污染质的净化能力和污染范围。
