Product Name: Acetaldehyde  
Trade Mark: Sanren Brand  
Alternative Name: ?  
Molecular formula/Structural Formula:
Production Process: Using ethylene and oxygen as raw material, the product is made through one-step direct oxidation in presence of liquid phase catalyst.  
Properties: The product is a colorless transparent liquid with a pungent irritating smell, very volatile and combustible. It can mix with water, ethanol, ether and chloroform. Polymerization would take place with the presence of concentrated sulphuric acid. It can be easily oxidated. There exists the danger of explosion when encountering spark, high temperature, strong oxidant and ammonia, hydrogen sulfide, halogen, phosphorous, strong alkali and so on. Its vapor and air could form an explosive mixture. Its relative density is 0.783(20℃),boiling point 20.2℃, flash point ?9℃(close cup), autoignition temperature 175℃,explosion limits 4.0%~57%.  
Grade: 牋
