The application markets of three kinds of isoolefines(isoprene, cyclopentadiene ,piperylene) from the cracking C5 fractions and their downstream derivatives were reviewed.

着重评述了裂解C5馏分资源中3种异构烯烃(异戊二烯、环戊二烯和间戊二烯)及其下游衍生物的应用市场，并剖析了我国裂解C5资源的利用现状及应用前景。

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。

The mixture of Z-11-hexadecenyl acetate and Z-11-hexadecenol (4 : 1 or 9: 1) proved to be attractive to the male moths of Pseudaletia separata Walker in Japan was less attractive to the male moths of Mythimna separata Walker in North China during the second flying season.

在顺—11—十六烯醛中加入少量顺—11—十六烯醇乙酸酯(1—10％)，能显著地提高诱蛾活性。同时表明在日本活性很高的粘虫诱芯(顺—11—十六烯醇乙酸酯及顺—11—十六烯醇比例为8：1或9：1)在中国北方诱到的粘虫雄蛾数量极少。

Molybdophopsphoric Acid Catalysis in the Oxidative Cleavage of Olefins by the Hydrogen Peroxide Oxidative cleavage of the double bond could be catalyzed by H_3PMo_(12)O_(40) using H_2O_2 as oxidant, various trisubstituted olefins were oxidized to aldehydes or ketones in high yields. The system was not satisfied for electron-deficient olefins such as trans-(2-nitrovinyl) benzol or chalcone. The reaction of aliphatic olefins did not occur under the same conditions.

二、磷钼酸催化过氧化氢对烯烃的氧化断裂反应用过氧化氢(30％)作为氧化剂，磷钼酸可以催化氧化碳碳双键的断裂反应，三取代的烯烃被氧化生成醛或酮，产率较高；此体系对于缺电子烯烃如查尔酮，不饱和硝基化合物的断裂反应效果较差，脂肪族烯烃在此体系下的氧化并不发生。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
