By means of the constructed ternary phase diagrams of these systems,it is found that the binodal curve of ScCO_2/acetone/CA system is quite close to the polymer/solvent axis.

3通过理论计算，获得了ScCO_2/丙酮/CA、ScCO_2/甲苯/PSt及ScCO_2/溶剂/PVB铸膜体系的三元相图。

Methods Seventy-three patients with clinically and biochemically documented phenylketonuria were studied with use of 0.5 T superconductive MRI.

Just prior to the analysis, prep a re the test solution by adding 0.5ml of the bromophenol blue indicator solution to each 100ml of the aqueous acetone solution and titrating with 0.01 N HCl or 0.01 N NaOH until the test solution is just yellow in color.

分析前准备好测试溶剂，100ml含2%水的丙酮加到锥形瓶中，加0.5ml 1%溴酚蓝水溶液指示剂，用0.01N NaOH溶液滴定至绿色或蓝色，然后用0.01N 盐酸标准溶液滴定至刚好呈黄色

Methods:The target compound was synthesized using 4-hydrazino-N-methyl-benzyl-sulphonamide hydrochloride and 4,4-dimethoxy-N,N-dimethyl butylamine as the starting materials,PPA and sodium dihydrogen phosphate instead as catalysts and isopropyl ether and acetone as solvents for recrylstallization,via 4-step reactions:condensation,rearrangement,cyclization and salt formtion.

以4-肼基-N-甲基-苄基磺酰胺盐酸盐与4，4-二甲氧基-N，N-二甲基-丁胺为起始原料，改用多聚磷酸和磷酸二氢钠作为催化剂，后处理采用异丙醚和丙酮作为重结晶溶剂，经缩合、重排、环合、成盐的4步反应合成琥珀酸舒马曲坦。

To study the chemical constituents from the leaves of Celastrus gemmatus Loes., chromatographic methods were used to isolate and purify the chemical constituents, their structures were elucidated by the physiochemical characteristics and spectral data.

为研究哥兰叶(Celastrus gemmatus Loes。)中的化学成分，用Diaion HP-20，Toyopearl HW-40，silica gel等柱色谱方法，从其70﹪含水丙酮提取物中分离得到化合物，并根据理化性质和波谱数据鉴定其结构。

The model was applicable to most of the organics in the experiment, and wasnot well applicable to acetone and chloroacetic acid.

模型对大部分试验有机物都适用，对丙酮和氯乙酸的适用性较差。

When acetone oxime was used as substrates, lower conversion and selectivity were obtained. For cyclopentanone oxime as the substrate, the Beckmann fragmentation was observed.

对于丙酮肟和环戊酮肟，前者重排得到N-甲基乙酰胺的选择性低，后者则不发生Beckmann重排。
