摘要
以1，4—苯二酚和不同的短链脂肪酸为基本原料，经溴代、加成、形成酰卤和酰化等反应，合成了六种新的溴化脂肪酸—2，3，5，6—四溴—1，4—苯二酯。通过对产物的碳、氢、溴等元素的定量分析，以及红外吸收光谱和氢核磁共振谱的研究，验证了化合物的结构。
Six new brominated carboxylates of 2, 3, 5, 6 - tetrabromo - 1, 4 - dihydroxybenzene (TBHQ) have been synthesized from short - chain aliphatic acids and pbenzenediol via the following steps: substitution (bromination), addition, preparing acyl halide, and acylation of TBHQ. The structures of the esters have been identified by means of quantitative analysis of C,H, Br and infrared spetroscopic examination and proton nuclear magnetic resonance studies.
