危险化学品分类与危害说明

物理形态与操作说明

• Crotonaldehyde, stabilized appears as a clear colorless to straw colored liquid with a penetrating pungent odor. Flash point 55 °F. 密度 7.1 lb / gal. Very toxic by inhalation. May polymerize with the release of heat under exposure to heat or contamination. If polymerization takes place inside a container, the container may rupture violently. Less dense than water. Vapors heavier than air.
• (e)-crotonaldehyde is a water-white to straw-colored liquid with a pungent, suffocating odor. Used as a chemical intermediate in a variety of industrial processes (surfactants, textiles, paper, fuels, insecticides, leather tanning, etc.). Used in chemical warfare. (EPA, 1998)
• Liquid
• Water-white liquid with a suffocating odor; Note: Turns pale-yellow on contact with air; [NIOSH]
• Water-white liquid with a pungent suffocating odor; [HSDB]
• COLOURLESS LIQUID WITH PUNGENT ODOUR. TURNS PALE YELLOW ON EXPOSURE TO LIGHT AND AIR.

数据库记载的用途

• Used in the synthesis of other organic chemicals; [ACGIH]
• Used to make other chemicals (n-butyl alcohol, quinaldine, crotonic acid, 2-ethylhexyl alcohol, butyraldehyde, surface-active agents, resins, rubber antioxidants, textile and paper sizes, insecticides, and flavoring agents); Also used as a fuel-gas warning agent, solvent for polyvinyl chloride and purification of mineral oils, alcohol denaturant, leather tanning agent, to locate breaks and leaks in pipes, and in chemical warfare; [HSDB]
• Petroleum Production and Refining [Category: Industry]
• Leather Tanning and Processing [Category: Industry]
• Crotonaldehyde was formerly used in the manufacture of n-butanol, but currently, the most extensive use of crotonaldehyde is in the manufacture of sorbic acid. Crotonaldehyde has also been used as a warning agent in fuel gases, in the preparation of rubber accelerators, in leather tanning, as an alcohol denaturant, and as a stabilizer for tetraethyl-lead.
• Manufacture of butyl alcohol, butyraldehyde, methoxybutyraldehyde, sorbic acid, maleic acid, crotonic acid, crotyl alcohol. In polymer chemistry: manufacture of resins and polyvinyl acetals, solvent for polyvinyl chloride, rubber antioxidant, increases rubber strength with ketones. In prepatation of insecticides and fertilizers. In production of flavors.
