Environmental hazards: harmful to the environment.
Danger of explosion: This product is extremely flammable and irritating.
Hazard characteristics: flammable, its vapor and air can form an explosive mixture, which is easy to burn and explode in case of open flame and high heat. Contact with oxidant and react violently. In case of high heat, polymerization can occur, releasing a lot of heat, causing container rupture and explosion accidents. Its vapor is heavier than air, and it can spread to a considerable distance at a lower place, and it will catch fire when it meets a fire source.
Present situation at home and abroad: Propanal is one of the basic raw materials for fine chemical production and has a wide range of uses. In 20 10, the global production of propionaldehyde was about 4 10000 tons, of which the United States accounted for about 60%, and others were mainly concentrated in German, China, South Africa and other countries and regions. In 20 10, China's apparent consumption was about120,000 tons, and its production capacity was110,000 tons/year, mainly concentrated in Zibo Nuoao Chemical Co., Ltd. and Yangzi-BASF Co., Ltd., with production capacities of 70,000 tons/year and 40,000 tons/year respectively. The production process of both companies is carbonyl synthesis, and the former propionaldehyde is mainly used to process n-propanol. Because of its easy oxidation, easy polymerization and inconvenient transportation, it is rarely imported.
