2,3,5,6-四氨基吡啶及其(2-羟基)对苯二甲酸复合盐的合成
Synthesis of 2,3,5,6-tetraaminopyridine and its 2-hydroxyterephthalic acid composite salt
摘要
Abstract
In order to prepare the composite salt of 2,3,5,6-tetraaminopyridine and 2-hydroxyterephthalic acid (TH salt) with high purity and yield,the 2,3,5,6-tetraaminopyridine hydrochloride(TAPH) was successfully reduced by catalytic hydrogenation from 3,5-dinitropyridine-2,6-diamine(DADNP) as raw material. TAPH was obtained with the purity of 99.4%and the yield of 82.1%in hydrogen and 55~60℃ condition,the solvent is methanol and the catalyst is Pd/C. Under the protection of the nitrogencondition,the TAPH and 2-hydroxyterephthalic acid(HTA) sodiumsalt were taken as raw materials to make the composite salt of 2,3,5,6-tetraaminopyridine with 2-hydroxyterephthalic acid(TH salt). All chemical structures of the products were identified by 13C-NMR,MS and FT-IR,the result showed that the product was the aim product and its purity was up to 98%.关键词
