The influence of CFC-12 content, effect of fluorination temperature and fluorinating time on the structure and hydrodesulfurization activity of the catalysts were examined systematically. The results revealed that hydrodesulfurization activity of the catalyst fluorinated by 1% CFC-12 at 623 K was obviously improved With an increase of 20%-30% as compared With that of the unfluorinated catalyst, the commercially available BY2 catalyst, and NH4F-fluorinated catalysts.

通过对0.5%~7%各种氟里昂浓度和473~773K各种温度及不同时间氟化处理的样品进行详细考察,发现在623K下由含氟里昂1%的湿空气氟化的载体制备的催化剂样品,其噻吩的加氢脱硫的活性有明显改善,相对於非氟化样品、BY-2工业催化剂以及氟化铵溶液浸渍处理的催化剂活性提高20%~30%,且非常稳定。

The result of above three aspects indicates:(1) under these optimize conditions,the yield of nitrating reaction is 95.52%, the yield of phase transfer catalysis fluorination is 90.03%, the yield of chlorination is 87.5%,and the reaction total yield is 75.47%, which are higher than the yields reported, the purity of product is 98.5%.

上述研究结果表明:(1)在实验所得的工艺条件下,硝化收率为95.52%,相转移催化收率为90.3%,氯化收率为87.5%,反应总收率达到75.47%,产品纯度为98.5%,均高于文献所报导收率。

Fluorination modification and electret properties were studied on the cellular polypropylene films modified by gaseous fluorine, by attenuated total reflection infrared analysis and the measurings of open-circuit thermally stimulated discharge current and in situ TSD charge and isothermal charge decay.

通过衰减全反射(Attenuated Total Reflection, ATR)红外光谱分析与开路热刺激放电(Thermally Stimulated Discharge, TSD)电流、原位实时电荷TSD和电荷等温衰减的测量,本文研究了氟气对孔洞聚丙烯膜的氟化改性及氟化改性对其驻极性能的影响。
