查询词典 acetylene

The graphite and acetylene black are added to a anode material in making Zn-Mn battery, therefore the sample solution prepared appears as feculency and the titration end point of the solution is difficult to judge when active manganese in the battery is determined by iodimetry with starch as a indicator.

在测定锌锰干电池锰粉中活性二氧化锰含量时，由于制备电池时正极锰粉中添加了乙炔黑、石墨等导电材料，使制得的样品溶液显色且混浊，影响用淀粉作为指示剂进行碘量法滴定终点的判断。

采用涂膜法制备了以碳纳米管、乙炔黑和石墨粉为导电填料的导电胶，研究了它们的电学性能、力学性能和粘结性能。结果显示，聚偏氟乙烯/CNTS导电胶有较好的综合性能

In particularly, we conducted a deep discussion on potassic testing conditions using the TAS-986 model atomic absorbing spectrophotometer, with a flaming (air - acetylene ) approach.

尤其是对TAS—986型原子吸收分光光度计用火焰法测钾的条件作了深入的探讨。

Examples of highly unsaturated hydrocarbons include without limitation acetylene, methylacetylene and propadiene.

高度不饱和烃的实例包括但不限于乙炔、甲基乙炔和丙二烯。

In an embodiment, the selective hydrogenation catalysts of this disclosure are used in the hydrogenation of highly unsaturated hydrocarbons such as for example and without limitation acetylene, methylacetylene, propadiene or combinations thereof.

在实施方案中，本公开的选择性加氢催化剂被用于高度不饱和烃的加氢中，其中所述高度不饱和烃例如但不限于乙炔、甲基乙炔、丙二烯或它们的组合。

The unsaturated hydrocarbon stream 10 primarily comprises one or more unsaturated hydrocarbons, but it also contains one or more highly unsaturated hydrocarbons such as for example and without limitation acetylene, methylacetylene and propadiene.

所述不饱和烃料流10主要包含一种或多种不饱和烃，但它也含有一种或多种高度不饱和烃例如但不限于乙炔、甲基乙炔和丙二烯。

The main objective of this research project is to modify the Methyl-Acetylene/propadiene selective hydrogenation reaction system of the No.3 Naphtha Cracker in CPC. The original gas phase reaction system was redesigned to a liquid phase reaction so that higher propylene selectivity was achieved and lower rates of propane and green oil were produced. To recover effectively the higher production of valuable propylene from the reaction system, the following fractionator was also redesigned.

本研究之目的在於修改中油公司三轻工场老旧的甲基乙炔／丙二烯选择性氢化气相反应系统，使成为液相反应系统，藉由液相反应的优异性，提高由MAPD氢化得到丙烯之选择率，同时降低丙烷及绿油产率，以增加丙烯产率，另亦修改丙烯精馏系统，以提升蒸馏塔提纯之效率。
