摘要
利用塔拉粉直接制备３，４，５三甲氧基苯甲酸甲酯，研究了塔拉渣的不同分离时机和分离方式。结果显示塔拉渣的最优分离时机为“蒸水／水解”步骤前，可以实施的分离方式为筛网真空抽滤。
Methyl 3,4,5 trimethoxybenzoate was directly prepared from tara powder. Different steps and modes for separating tara residue were studied. Experimental results showed that separation of tara residue was reasonable in the step before evaporation and hydrolysis, and practical mode for separating tara residue was vacuum filtration by sieves.
