Abstract
The hydrolysis of 3-bromo-4-hydroxybenzaldehyde in ionic liquid 1-allyl-3-methyl-imidazolium [Amim]Cl was studied.The effect of reaction conditions was investigated.When the reaction temperature is 100℃,the reaction time is 2 h,the quantity of catalyst is 6.4 g per mole reactant,the volume of [Amim]Cl is 1.2 L per mole reactant and the amount of NaOH is 2 mol per mole reactant,the yield of the hydrolysis reaction can reach 83.6% and the purity of product can reach 99.4%.The ionic liquid [Amim]Cl can be recycled facilely and reused.
