Chemical properties: is a white crystalline powder, soluble in alcohol, ether and hot water, ferric chloride will become a case of pink Mp 232-233 ° C. Soluble in ethanol, ether, acetone and hot water. And fuming sulfuric acid or hot concentrated sulfuric acid generated purple compounds. And ferric chloride role was wine.
Usage:
1 For organic synthesis intermediates for pharmaceutical, synthetic resins 2.Used in organic synthesis
Brief manufacture process:
By benzoic acid by sulfonation, alkali melting, acidification derived. Benzoic acid with fuming sulfuric acid at 240-250 ° C sulfonation 5h, 3,5-disulfonic acid benzoic acid, sodium hydroxide at 300 ° C alkali fusion, the reaction of sulfuric acid and neutral to weakly alkaline, Filtered, concentrated, and then acidified to weak acid, extracted with ether. Recovering the ether extract from the crude water recrystallization derived products.
