助催化剂英语

催化剂：catalytic agent反应条件：reaction conditionscatalytic 英[ˌkætə'lɪtɪk] 美[ˌkætlˈɪtɪk] adj. 接触反应的; 起催化作用的; n. 催化剂; 刺激因素; [例句]Governments do, however, have a vital catalytic role in orchestrating rescue operations.然而，政府在组织协调救援行动上确实发挥了重要的促进作用。agent 英[ˈeɪdʒənt] 美[ˈedʒənt] n. 代理人; 代理商; 特工; 药剂; vt. 由…作中介; 由…代理; adj. 代理的; [例句]You are buying direct, rather than through an agent.你这是直接购买，而不是通过代理人。[其他] 复数：agents

催化剂英语是catalyst，所以缩写的话往往写成C

1,8-Naphthalimide-type compounds are important fluorescent materials. This paper reported the preparation of 4,5-di(p-methylphenylacetylenyl)-1,8-naphthalimide. Tar-acenaphthene was used as starting material which was converted to 4,5-dibromo-1,8-naphthalimide through bromination, oxidation, condensation, and other steps. 4,5-Di(p-methylphenylacetylenyl)-1,8-naphthalimide was prepared through Sonogashira coupling using Pd(PPh3)2Cl2 as catalyst, CuI as co-catalyst, and ethanol as solvent. The prepared compounds were characterized with NMR spectroscopy. Effects of solvents, temperature, reaction time and the amount of oxidant on the course of the oxidation reaction were studied. Effects of catalyst, co-catalyst, solvent and different halogen-substituted aromatic compounds on the course of Sonogashira coupling reaction were discussed.

1,8 - naphthalimide compound fluorescent material is important. In this paper, 4,5 - two pairs of methyl acetylene to replace benzene -1,8 - naphthalimide synthesis were studied. Acenaphthene as raw materials in order to tar by bromination, oxidation, condensation, and other steps of the synthesis of 4,5 - dibromo-replace -1,8 - naphthalimide. Using Sonogashira reaction to Pd (PPh3) 2Cl2 as a catalyst, CuI as catalyst, 4,5 - dibromo -1,8 - naphthalimide as raw materials in ethanol solvent in the synthesis of 4,5 - 2 pairs of methyl replace acetylene benzene -1,8 - naphthalimide, using nuclear magnetic resonance method of structural characterization of compounds. Study of different solvents, temperature, reaction time, oxidant amount on the effects of oxidation. Discussion of the catalyst, cocatalyst, solvent, and various substituted aryl halogen compounds on the impact of Sonogashira coupling reaction.

催化剂用英语表示为catalyst，因此催化剂的缩写应该是C
