测定5-氯-2戊酮和环丙基甲基酮的物化性质:密度、黏度、摩尔体积、热膨胀系数和表面张力。测定5-氯-2-戊酮(1)+环丙基甲基酮(2)二元体系的汽液相平衡(VLE),并应用Aspen Plus V11中Van Laar方程、Wilson方程和NRTL方程对实验数据进行关联...测定5-氯-2戊酮和环丙基甲基酮的物化性质:密度、黏度、摩尔体积、热膨胀系数和表面张力。测定5-氯-2-戊酮(1)+环丙基甲基酮(2)二元体系的汽液相平衡(VLE),并应用Aspen Plus V11中Van Laar方程、Wilson方程和NRTL方程对实验数据进行关联,回归得到二元交互参数。实验结果通过热力学一致性检查。该研究不仅补充了汽液相平衡数据库,也为5-氯-2-戊酮与环丙基甲基酮的分离提供热力学数据。展开更多
In this paper, 3 (2 chloro 5 pyridylmethyl)amino 2 cyano 3 methylthio ethyl acrylates 3 were synthesized. By the reaction of 3 as an intermediate with amines, 5 new 3 (substituted)amino 3 (2 chloro 5 pyridylmethyl)ami...In this paper, 3 (2 chloro 5 pyridylmethyl)amino 2 cyano 3 methylthio ethyl acrylates 3 were synthesized. By the reaction of 3 as an intermediate with amines, 5 new 3 (substituted)amino 3 (2 chloro 5 pyridylmethyl)amino 2 cyano ethyl acrylates were prepared. When 3 reacted with hydrazine, the corresponding cyclic compound 4f was obtained. The preliminary bioassays showed that compounds 3 has good herbicidal activity.展开更多
By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven step...By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven steps. The preliminary biological activity tests show that the title compounds reveal a certain plant growth regulating effect as well as fungicidal activity.展开更多
