乙二醛

乙二醛

黄色晶体。d20 1.14；熔点15℃，沸点51℃I折射率1. 3826。易溶于水，溶于醇和乙醚。不稳定，所以一般以40%～41%浓度的水溶液使用，其溶液为无色浅黄色透明液体，相对密度1. 260～1. 310。具有强还原性。接触空气能引起爆炸。遇水发生强烈聚合反应。与氯磺酸、亚乙基亚胺、硝酸、发烟硫酸、氢氧化钠发生强烈反应。燃烧时放出有毒的刺激性烟雾。

Glyoxal

Yellow crystals. d20 1.14;melting point 15 °C,boiling point 51 °CI refractive index 1. 3826。 Soluble in water, soluble in alcohol and ether. It is unstable, so it is generally used as an aqueous solution with a concentration of 40%~41%, and the solution is a colorless light yellow transparent liquid with a relative density of 1. 260～1. 310。 It has strong reducibility. Contact with air can cause an explosion. Strong polymerization reaction occurs in contact with water. It reacts strongly with chlorosulfonic acid, ethyleneimine, nitric acid, oleum acid, sodium hydroxide. When burned, it emits toxic and irritating fumes.
