The wholly aromatic four-component copolyesters were prepared from p-acetoxy-benzoic acid, hydroquinone diacetate, 2,6-naphthalene dicarboxylic acid and isophthalic acid by melting polycondensation. 由对乙酰氧基苯甲酸、对苯二酚二乙酯、2，6-萘二甲酸及间苯二甲酸四种单体通过熔融缩聚反应，合成了全芳香族四组分共聚酯。 - 2
The relative stereochemistry of the 1, 10-double bond and that of the methoxyl, methyl, and acetoxy groups were determined by NOESY experiments and analyses of the coupling constants. 通过NOESY实验以及偶合常数的分析，确定了其结构中1,10位双键和甲氧基、乙酰氧基、甲基等基团的相对构型。 - 3
We select the acetoxy group to protect the hydroxy group from a great number of the protection methods for the hydroxy group. 在众多的羟基保护方法中，选择了乙酰氧基对其进行了保护。
