The invention relates to a process for the preparation of a liquid composition of an ortho-dihydroxybenzyl compound of high purity characterized in that it consists inpurifying the initial ortho-dihydroxybenzyl compound by distillation and recovering the condensed ortho-dihydroxybenzyl compound in an apparatus resistant to corrosion by the latter, and then mixing it with an organic solvent in a storage tank which is lined or made of a material which does not lead to metallic pollution. The invention also relates to a liquid composition of an ortho-dihydroxybenzyl compound of high purity comprising said compound and an organic solvent of said compound obtained according to said process.
本发明涉及一种制备高纯度原二羟基苄基化合物的液体组合物的工艺,其特征在于它包括通过蒸馏净化初始原二羟基苄基化合物,并在一个耐后者腐蚀的装置中回收冷凝的原二羟基苄基化合物,然后在一个内衬或由不会导致金属污染的材料制成的储罐中将其与有机溶剂混合。本发明还涉及一种高纯度原二羟基苄基化合物的液体组合物,该组合物包括上述化合物和根据上述工艺获得的上述化合物的有机溶剂。
