[求助] 关于苯并噁嗪的文章,其中几句,求翻译,小弟在此多谢了!!!!

The values are relatively high when compared with the B-a/epoxy thermoset, which possesses 5% degradation temperature at 302-309, dependent on the curing catalyst [32].


Unlike the curing of neat ( 6) (Fig. 2), the characteristic peaks of oxazine did not disappear completely in the ( 6)/DCPDE system after curing at 220 C for 20 min, suggesting a slower curing rate.


The carbonyl signal, which was not seen after 140 C treatment, supports the formation of cyclic amide.


In contrast to the good solubility of ( 6), preparing benzoxazine ( 7) in chloroform (Run 8) and toluene/ethanol (Runs 9e10) results in powder precipitate (not gelation) after 1 h due to the poor solubility of ( 7), which limits the purity of ( 7).

The values are relatively high when compared with the B-a/epoxy thermoset, which possesses 5% degradation temperature at 302-309, dependent on the curing catalyst [32].
与B-a/环氧热凝物相比,这些数值相对较高。 在固化促进剂的作用下,B-a/环氧热凝物在302-309度的温度区间,发生5%的热降解。

Unlike the curing of neat ( 6) (Fig. 2), the characteristic peaks of oxazine did not disappear completely in the ( 6)/DCPDE system after curing at 220 C for 20 min, suggesting a slower curing rate.
与图2中整齐固化不同的是,在220摄氏度的环境中,经过20分钟的固化后,恶嗪的特征峰不会从DCPDE 系统中完全消失。

The carbonyl signal, which was not seen after 140 C treatment, supports the formation of cyclic amide.
羰基信号(在经过140摄氏度的热处理后会消失,或者不可见)能促进环酰胺的形成。

In contrast to the good solubility of ( 6), preparing benzoxazine ( 7) in chloroform (Run 8) and toluene/ethanol (Runs 9e10) results in powder precipitate (not gelation) after 1 h due to the poor solubility of ( 7), which limits the purity of ( 7).
与(6)良好的溶解度形成对比的是, 在氯仿(Run 8)和甲苯/乙醇(Runs 9e10)中,制备苯并恶嗪,会在1小时后, 由于(7)的溶解度较差,产生粉末沉淀物(非胶凝态),这制约了(7)纯度的提升。

第二句中貌似没翻译完,第三局感觉也有点问题。哎,伤心!
