实验性质
| 外观 / 形态 : | Benzaldehyde appears as a clear colorless to yellow liquid with a bitter almond odor. Flash point near 145 °F. More denser than water and insoluble in water. Hence sinks in water. Vapors are heavier than air. The primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways. Used in flavoring and perfume making.；CBI; Liquid；Colorless to yellowish liquid with an odor of almond oil; [AIHA] In air, readily oxidizes to benzoic acid; [CAMEO]；Liquid；COLOURLESS-TO-YELLOW LIQUID WITH CHARACTERISTIC ODOUR.；colourless to yellow liquid with a sweet, strong almond odour |
