The thermal desorption spectra of propene and oxygen adsorbed on blue tungsten oxide WO_(2.90) have been measured by means of flash heating the sample in ultra high vacuum. It has been discovered that at room temperature only one adsorption state of propene on blue tungsten oxide surface exists, which corresponds to a desorption peak at the temperature around 100℃ appeared in the thermal desorption spectra. The desor-. ption parameters determined by the experiment are: n=l (first order desorption) and the activation energy of desorption E_d=10.1 kcal/mol. The probability of forming stable adsorption state of propene on blue tungsten oxide decreases as the sample temperature increases. At room temperature, the blue tungsten oxide doesn't interact with oxygen significantly. But after raising the temperature to above 300℃, WO_(2.90) is oxidized into W03 accompanying with a strong adsorption of oxygen. This implies that the blue tungsten oxide could be used as a promising oxygen getter in the vacuum valves.

在超高真空条件下,用对样品进行闪烁加热的方法测定了蓝色氧化钨WO_(2.90)吸附丙烯和氧的热脱附谱。发现在室温下,丙烯在蓝色氧化钨表面只有一个吸附态,对应于热脱附谱中在100℃附近出现一个脱附峰。实验测定的热脱附参数为n=1(一级脱附),脱附活化能E_d=10.1kcal/mol。温度升高,丙烯在蓝色氧化钨表面形成稳定吸附态的几率减小。在125℃以上,不能形成稳定的吸附态,蓝色氧化钨在室温下对氧的吸附并不明显,温度升高到300℃以上,WO_(2.90)具有极强的吸氧能力,同时本身被氧化成WO_3。这一现象有可能使蓝色氧化钨被用于电真空器件中作为一种氧的消气剂。

The characteristics and kinetics of oxygen absorption of Shanjiasi, Shengli and Renqiu road asphalts and their constituents, i. e. saturates, aromatics,resins and asphaltenes, were investigated by means of precisely measuring the change of oxygen pressure in the reactor.

把单家寺、胜利和任丘道路沥青及其分离组分——饱和烃组分、芳香烃组分、胶质和沥青质制成1mm厚的样品薄膜,采用精确度较高的压力法在50℃、0.13MPa(O↓2)无光照条件下,研究了沥青及其组分的吸氧性能和动力学规律。结果表明,饱和烃组分基本上不吸氧;其次为芳香烃组分;胶质和沥青质的吸氧能力最强,是沥青中最不稳定的组分。对于所试验的直馏沥青而言,抗老化性能好的沥青,其组分的抗老化性能也好。用粘度较低、基本上不吸氧的饱和烃组分稀释沥青质后,沥青质的吸氧速度变大。单家寺沥青的胶质能明显改善胜利沥青的抗老化性能。动力学研究表明,本文所提出的最大化合氧数学模型很好地解释了沥青及其组分的吸氧规律,理论计算值与实测值能够很好地吻合。

The catalysis or carrying oxygen functions of ferric,ferrous and cobal-tous coordination compounds of 5[p-[4-(m-pyridyloxy)butoxy]phenyl]-10,15,20-triphenylporphyrin(PyBPTPP)have been studied respectively.Hydroxylation ofeyclohexane to cyclohexanol and cyclohexanone was studied by the systems consi-sting of the synthetic metalloporphyrins,ascorbic acid and substrate as a modelsystem of cytochrome P450 monooxygenase.The dioxygen uptaking abilities ofthese systems were determined.The yields of hydroxylation products were measured by gas chromatography.The results indicated that the ferric tailed porphyrincomplex Fe(Ⅲ)PyBPTPPCI is more efficient than the simple corresponding onesfor the hydroxylation.This suggests that the presence of an axial ligand,whichis covalently linked to the porphyrin ring,greatly increase the catalytic efficien-cy.The oxygen-carrying abilities of the tailed Co(Ⅱ)porphyrin complex,Co(Ⅱ)PyBPTPP were determined by UV-Vis spectrophotometry.This model com-pound exhibited oxygen-carrying capacity reversibly in benzene solution at roomtemperature.The oxygen molecule in the end group fashion coordinate to the cen-ter cobalt of the porphyrln ring in oxymetalloporphyrin complex was proved fur-ther by infrared spectra.
