摘要
丁香酚是丁香油的主要成分,经NaOH盐渍、h2so4水解、正己烷配分、真空蒸馏纯化得到丁香油。经气相色谱分析,丁香酚纯度为97.70%,纯度为71% (v/v)。从丁香酚中分离得到的2-(4-烯丙基-2-甲氧基苯氧基)- n, n -双(2-羟乙基)乙酰胺化合物可经烷氧基化、酯化、酶促合成,具有抗菌或药用的潜力。采用Williamson法,将丁香酚中的羟基官能团氢氧化钠转化为丁香酸钠,然后在回流条件下用α-一氯乙酸取代得到丁香酸酯。所得酸用乙醚/Na2CO3萃取,热水重结晶,固相率为70.52%。在回流条件下,以H2SO4为催化剂,在苯溶剂中与甲醇酯化乙酸丁香酚甲酯,产率为81.36%。二乙醇胺催化甲基丁香酚醋酸酯的酶解,甲醇溶剂催化甲氧基钠回流。纯化后的2-(4-烯丙基-2-甲氧基苯氧基)- n, n -二(2-羟乙基)乙酰胺固体化合物收率为72.99%。用红外光谱分析了丁香酚分离物、丁香酚乙酸酯和丁香酚乙酸甲酯的结构,用红外光谱和核磁共振光谱分析了2-(4-烯丙基-2-甲氧基苯氧基)- n, n -双(2-羟乙基)乙酰胺化合物。
Synthesis of 2-(4-Allyl-2-Methoxy Phenoxy)-N,N-Bis(2- Hydroxyethyl) Acetamide from the Transformation of Eugenol Isolated from Clove Oil
Eugenol as the main component of clove oil has been isolated through NaOH salting procedure followed by H2SO4hydrolysis, n-hexane partitioning and purification with vacuum distillation. 71% (v/v) eugenol was produced with purity of 97.70% based on gas chromatography analysis. 2-(4-allyl-2-methoxy phenoxy)-N,N-bis(2-hydroxyethyl) acetamide compound has the potential as antibacterial or substances for medicine in pharmaceutical can be synthesized from eugenol isolated through alkoxylation, esterification and followed by amidase. Alkoxylation was done using Williamson method through NaOH transformation of hydroxyl functional group in eugenol to form sodium eugenolate then with α-monochloroacetate substitution in reflux condition, eugenyl acetate was produced. The acid produced was extracted with ether/Na2CO3, followed by recrystallization using hot water and produced 70.52% solid form. Eugenyl acetate esterification with methanol in benzene solvent with H2SO4 catalyst in reflux condition produced methyl eugenol acetate liquid with 81.36% of yield. Amidase of methyl eugenol acetate with diethanolamine and sodium methoxide catalyst with methanol solvent in reflux condition. After purification, 2-(4-allyl-2-methoxy phenoxy)-N,N-bis(2-hydroxyethyl) acetamide compound in solid form is produced with 72.99% yield. Eugenol isolated, eugenyl acetate and methyl eugenol acetate had their structures analyzed with FT-IR spectroscopy while 2-(4-allyl-2-methoxy phenoxy)-N,N-bis(2-hydroxyethyl) acetamide compound was analysed using FT-IR and H1-NMR.
