Essential information

Colorless or yellow crystals or liquids with deliquescence. Dissolve in ethanol, ether, and water. It is chemically active and can undergo addition or condensation reactions with ammonia, amides, aldehydes, and compounds containing carboxyl groups. Mainly used in the textile industry. Produced by gas-phase catalytic oxidation of ethylene glycol and air.

Application area 

Acetaldehyde is mainly used in the textile industry as a fiber treatment agent to increase the spinning shrinkage and wrinkle resistance of fibers such as cotton and nylon. It is a durable ironing finishing agent. In Japan, this use accounts for 80% of the total consumption of formaldehyde. Acetaldehyde is an insoluble adhesive used in gelatin, animal glue, cheese, polyvinyl alcohol, and starch. It is also used in the leather industry and in the production of waterproof matches. Acetaldehyde is a raw material for organic synthesis. 2D resin is obtained by heating and condensing acetaldehyde, urea, and formaldehyde in the presence of sodium carbonate, and is used as a fabric finishing agent; Acetaldehyde reacts with formaldehyde and ammonium sulfate to form imidazole, which is then used to synthesize imidazole antifungal drugs such as clotrimazole and miconazole; Benzopyrazine is obtained by cyclization of glyoxal with o-phenylenediamine: it is an intermediate of the anti tuberculosis drug pyrazinamide. Hydroxyphenylacetic acid produced from glyoxal has been manufactured in Japan as an intermediate for antibiotics and vitamin A series products. It is also used as a insecticide, deodorizer, corpse preservative, and sand mold hardener.

Packaging, Storage, Transportation, and Safety

Storage precautions: Products are usually stored after dilution. Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants, alkalis, and edible chemicals, and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.
