补充资料：丁二酸
| 丁二酸 succinic acid 分子式HOOCCH2CH2COOH。又称琥珀酸。除存在于琥珀外，还广泛存在于多种植物及人和动物的组织中，例如末成熟的葡萄、甜菜和大黄，人的血液和肌肉，牛的脑、脾、甲状腺等。无色晶体。 188℃ ，235℃时分解，相对密度 1.572 (25/4℃) ；在减压下蒸馏可升华 。能溶于水，微溶于乙醇、乙醚和丙酮中。 工业上，丁二酸常由丁烯二酸催化原制得；也可由丁二腈水解制备。在实验室中可用两分子丙二酸二乙酯的钠盐与碘反应，经水解脱羧制得。丁二酸主要用于制备五元杂环化合物，例如丁二酸受热失水生成丁二酸酐，丁二酸酐是制造药物、染料和醇酸树脂的原料 。丁二酸在医药上有抗痉挛、祛痰和利尿作用。丁二酸二乙酯是有机合成的中间体；二丁酯、二辛酯是塑料的增塑剂。 |
