Crotonaldehyde is a chemical compound with the formula CH 3 CH=CHCHO. The compound is usually sold as a mixture of the E- and Z-isomers, which differ with respect to the relative position of the methyl and formyl groups. The E-isomer is more common (data given in …

巴豆醛，是一种有机化合物，化学式为C4H6O，有顺式和反式两种双键异构体，因顺式异构体不稳定，一般巴豆醛是指反式异构体，为无色透明液体，是重要的有机合成中间体，主要用于制备正丁醇、正丁醛、橡胶硫化促进剂、酒精变性剂和革柔剂等。 2017年10月27日，世界卫生组织国际癌症研究机构公布的致癌物清单初步整理参考，巴豆醛在3类致癌物清单中。 [2] 人经眼：45ppm，引起刺激。 微生物致突变性：鼠伤寒沙门菌100μl/L。 精子形态学：小鼠腹腔30mg/kg。 DNA加 …

Crotonaldehyde, a highly electrophilic a, b-unsaturated aldehyde, is a ubiquitous environmental pollutant and a risk factor for multiple respiratory diseases. Crotonaldehyde is highly volatile and hydrophilic, so it is efficiently absorbed in the respiratory tract.

What is crotonaldehyde? Crotonaldehyde is a colorless to pale-yellow liquid with a strong, pungent odor.

Crotonaldehyde is an intermediate in the synthesis of chemicals including quinaldines, thiophenes, pyridines, and 3-methoxybutanol, which is a speciality solvent used in lacquers and varnishes to control viscosity, drying behaviour, and gloss. Crotonaldehyde can also be used to control polymerization.

Crotonaldehyde is a clear, colorless to straw colored liquid with a strong, suffocating odor. It is highly flammable and produces toxic vapors at room temperature. Crotonaldehyde is found naturally in emissions of some vegetation and volcanoes; many foods contain crotonaldehyde in …

Crotonaldehyde is produced principally as an intermediate for the production of sorbic acid. It was formerly used in large amounts in the production of n -butanol. Crotonaldehyde occurs naturally in foods and is formed during the combustion of fossil fuels (including engine exhausts), wood and tobacco and in heated cooking oils.

巴豆醛主要用作矿物油的纯 化用溶剂、有机合成中间体、色谱分析标准物质、橡胶硫化促进剂、酒精变性剂、鞣剂、抗氧剂及杀虫剂。 巴豆醛是常用的有机合成原料，用于制取正丁醛、正丁醇、2-乙基己醇、山梨酸、3-甲氧基丁醛、3-甲氧基丁醇、丁烯酸、喹哪啶、顺丁烯二酸酐及吡啶系产品。 另外，丁烯醛与丁二烯反应可制得环氧树脂原料及环氧增塑剂。 与季戊成四醇反应可得到耐热树脂原料。 丁烯醛还可用于制取选矿用发泡剂、染料及橡胶抗氧剂、杀虫剂及军用化学品。 …
