This thesis consists of four chapters : ( 1 ) a review ; ( 2 ) study on the optical chemical membrane for detection of lead ion by using 2 - hydroxy - 1 - naphthaldehydene - 8 - aminoquinoline as fluorescence indicator ; ( 3 ) study on the optical chemical membrane for detection of lead ion by using meso - ( 4 - methyloxyphenyl ) porphyrin as fluorescence indicator ; ( 4 ) study on the optical chemical membrane for detection of lead ion by using 2 - methene - benzimidazole monoaza - 18 - crown - 6 as fluorescence indicator. in chapter one, the laboratory method for determination of lead ion, the progresses of chemical sensor for detection of lead ion recently and the introduction of the basic theory, relative merits of sol - gel and its application in optical chemical sensor were involved
第二章利用有機改性的溶膠-凝膠包埋方式，以2 -羥基- 1 -萘甲醛- 8 -氨基喹啉為熒光指示探針，結合正交實驗方法探索了幾個重要因素，如加水量、醇硅比、催化劑、添加劑等對成膜性的影響，制備了對水中鉛離子有較好響應的傳感膜，其線性范圍為1 . 0 10 - 7 ~ 5 . 0 10 - 5mol / l ，檢測限為3 . 6 10 - 8mol / l 。Abstract : aim to synthesize a new prodrug, resveratrol trinicotinate. methods in presence of lithium and a catalytic amount of naphthalene, the reaction of p - methoxybenzyl trimethylsilyl ether and 3, 5 - dimethoxylbenzaldehyde gave resveratrol after a series of translation. resveratrol trinicotinate was obtained by the reaction of resveratrol and nicotinoyl chloride hydrochloride. results a mutual prodrug resveratrol trinicotinate was designed and synthesized. conclusion a novel method for synthesis of resveratrol and resveratrol trinicotinate has been afforded. the e - isomer is selectivily obtained by dehydration of the compound 2 with khso4
文摘:目的合成一種前藥白藜蘆醇煙酸酯.方法在金屬鋰片和催化量的萘的存在下， 3 ， 5 -二甲氧基苯甲醛與對甲氧基苯甲醇的三甲基硅醚反應經過一系列轉變得到白藜蘆醇，白藜蘆醇與煙酰氯反應得到白藜蘆醇煙酸酯.結果設計併合成了白藜蘆醇煙酸酯.結論提供了一種合成白藜蘆醇及白藜蘆醇煙酸酯的方法，採用khso4脫水可選擇性的得到反式產物Auto data processing by tofms software combined with “ structured chromatogram ” was used to assign the components. 250 phenols were tentatively idenitified including 66 alkylphenol derivatives, 47 alkenylphenlo derivatives, 57 naphthalenol derivatives, 17 phenylphenol derivatives, 32 methoxyphenol derivatives, 9 acylphenol derivatives and 15 hydroxybenzaldehyde deriviatives
這些酚類化合物包括66個烷基苯酚、 47個烯基苯酚、 57個萘酚、 17個苯基苯酚、 32個甲氧基苯酚、 9個酚酮和15個酚醛化合物。
