水楊醛中文同義詞: 2-羥基苯甲醛；鄰羥基苯甲醛；鄰羥苯甲醛；水揚醛英文名稱: Salicylaldehyde 英文同義詞: FEMA 3004；2-FORMYLPHENOL；2-HYDROXYBENZALDEHYDE；(2-HYDROXYPHENYL) METHANAL；AKOS BBS-00003186；O-HYDROXYBENZALDEHYDE；SALICYLIC ALDEHYDE；SALICYLALDEHYDE CAS號: 90-02-8 分子式: C7H6O2 分子量: 122.12 EINECS號: 201-961-0 化學(xué)性質(zhì)：無色油狀液體或暗紅色油液，稀釋時呈苦杏仁似香氣，有灼熱味感。熔點-7℃，沸點196.5℃，折射率(nD25)1.5740，相對密度(d2525)1.1690。溶于乙醇、苯及大多數(shù)有機(jī)溶劑，微溶于水。遇三氯化鐵呈紫色。天然品存在于肉桂等中。含量：99.5% 作用與用途：該品為香料和其他有機(jī)合成的中間體。我國GB 2760-86規(guī)定為允許使用的食用香料，主要用以配制肉桂和堅果香精。水楊醛是一種香料，也是用途極廣的有機(jī)合成中間體。在合成中常用于合成水楊煙肼（Salinazid）、苯溴馬?。˙enzbromarone）和醋胺苯惡酮等。包裝：200公斤/塑料桶 Salicylaldehyde Synonyms: FEMA 3004；2-FORMYLPHENOL；2-HYDROXYBENZALDEHYDE；(2-HYDROXYPHENYL) METHANAL；AKOS BBS-00003186；O-HYDROXYBENZALDEHYDE；SALICYLIC ALDEHYDE；SALICYLALDEHYDE CAS: 90-02-8 MF: C7H6O2 MW: 122.12 EINECS: 201-961-0 Product Categories: Aromatic Aldehydes & Derivatives (substituted)；Amino Group Labeling Reagents for HPLC；Analytical Chemistry；HPLC Labeling Reagents；UV Detection (HPLC Labeling Reagents)；Aldehydes；Alpha Sort；Analytical Standards；Analytical/Chromatography；Building Blocks；C7；Carbonyl Compounds；Chemical Synthesis；Chromatography；Environmental Standards General Description Liquid； colorless or pale yellow； bitter almond odor. Sinks and mixes slowly in water. Reactivity Profile Salicylaldehyde is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic； they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Health Hazard LIQUID: Irritating to skin and eyes. Harmful if swallowed. Fire Hazard Combustible. Can react with oxidizing materials. Packing 200kg/plastic drum &#8203；
