採用聚乙烯醇縮丁醛和甲基纖維素對普通砂漿做合理改性,進行了96個抗剪試件的正交試驗,並對試驗結果進行正交分析。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The results indicate that the sort of walling material is the most important factor in bond capacity of mortar, the mixed quantity of polymer and mortar strength follows, and there is a remarkable increase in mortar bond strength when the mixed quantity of pvb and mc is 20 % ~ 30 % and 0. 05 % ~ 0. 1 % respectively
結果表明:塊體類別是最主要的影響因素,其次是聚合物摻量和砂漿強度;當聚乙烯醇縮丁醛和甲基纖維素的摻量分別為水泥質量的20 % ~ 30 %和0 . 05 % ~ 0 . 1 %時,可較大幅度提高砂漿的黏結強度。
