The gas-phase catalytic amination of iso-octanol has been preliminarily studied. The catalysts tried consist of alumina unpromoted or promoted by various oxides.Within the scope of the present investigation, the best catalysts have been found to be pure aluminium oxide and that composed of 95%Al_2O_3 and 5%gO.Systematic investigation has bsen made for the 95%Al_2O_3-5%MgO catalyst on the effects of such variables as reaction temperature, space velocity and inlet gas composition expressed in terms of mol ratio of ammonia to iso-octanol. The suitable reaction temperature observed is about 300℃. The maximum percent conversion obtained of iso-octanol to amines is 48% and the maximum percent yield on the basis of consumed iso-octanol, 78.5%.The effect on catalytic activity of the temprature of activation of the Al_2O_3-MgO catalyst mentioned above has also been preliminarily studied, the suitable temperature of activation has been found to be about 400℃.A lowered catalytic activity has been observed as a result of adding potash to the catalyst.

对异辛醇的气相催化胺化进行了初步的研究。所用催化剂是加有不同氧化物作为助化剂的氧化鋁催化剂和单一的三氧化二鋁。在本研究工作已完成的实驗范围中,較好的催化剂是95%Al_2O_3—5%MgO催化剂和純的Al_2O_3。在試驗中系統地研究了反应溫度、空間速度和进口反应气中氨对醇的分子比对胺化的影响;也初步地观察了催化剂的活化溫度和在催化剂中加碱对催化剂活性的影响。

The kinetics of gas phase oxidation of isobutene was studied in the range of 295—485℃ and 96—387 mm Hg. Under these conditions, no cool flame and negative temperature coefficient phenomenon was observed. The maximum reaction rate which is expressed in terms of the rate of pressure change follows the relationship:

在295—485℃,96—387毫米汞柱范围内研究了异丁烯的气相氧化。在这样的条件下,异丁烯的氧化溲有冷焰与负温度系数现象。在试验条件范围内,以压升量表示的最大反应速度遵守: 分析了异丁烯氧化的产品,除深度氧化产品H_2O,CO,CO_2外,产品中有多量的丙酮、甲醛(分别达原料异丁烯压力的50%和60%)和环氧化合物。产品中还有甲醇、甲烷、丙烯等。亦有乙醛、丙醛和异丁烯醛生成,但其总量不超过3毫米汞柱(5%)。根据所得结果,讨论了反应的机理。

The epoxidation of propene in gas phase has been investigated. About 10% of propylene oxide may be produced from the oxidation of pure propene. The formation of propylene oxide may be probably due to the following reactions:

研究了纯丙烯气相氧化的环氧化反应。生成的环氧丙烷为10%左右。讨论了环氧丙烷生成的途径。还研究了添加乙醛情况下的丙烯氧化。添加乙醛可以提高环氧丙烷的产率。在反应初期丙烯转化为环氧丙烷的定向性达80%以上,但乙醛有多量消耗。如果在反应初期仅加少量乙醛,则反应中同时生成的乙醛能补偿在反应中的消耗,此时环氧丙烷产率可达28.5%。乙醛在反应中的作用可能是生成过乙酸,然后与丙烯发生环氧化反应生成环氧丙烷。
