n-propylbenzene

The results show that when temperature is over 240 ℃, n-propylbenzene is increasing rapidly .

结果表明，当温度超过240℃时，正丙苯含量明显增加，而且温度越高，增加的量就越大。

The selectivity of cumene increased , the content of n-propylbenzene decreased by half and oligomers also decreased ;

研究的结果表明，引入适量磷的分子筛催化剂，显示出较好的催化性能，使得异丙苯的选择性有所提高，正丙苯含量减少了一半，丙烯齐聚物含量也略有降低。

It must be emphasized that n-propylbenzene content in the by-products and diisopropylbenzene from the air regeneration means were both higher than that from fresh catalyst .

在一定条件下空气再生的催化剂，其副产物中正丙苯含量和二异丙苯含量均高于新鲜催化剂水平。

Crystal Structure of 2 - ( 4 ' - n-Propylbenzene ) imidazole [ 2,1 - α ] isoquinoline

2-（4'-正丙基苯）咪唑并[2,1-α]异喹啉的晶体结构

The results show that the modification of H β zeolite by phosphorus suppresses acid strength and also significantly decreases the total amount of acid and the content of n-propylbenzene , and therefore the alkylation selectivity is increased ;

结果表明：磷使强酸受到抑制，正丙苯的含量较Hβ分子筛有显著下降，多异丙苯生成量有所降低，从而提高了Hβ催化剂的选择性；
