There are many production methods for acetaldehyde：
1. Ethylene direct oxidation method: Ethylene and oxygen is directly oxidized to synthesize crude acetaldehyde in one step through a catalyst containing palladium chloride, copper chloride, hydrochloric acid, and water, and then the finished product is distilled.
2. Ethanol oxidation method: Ethanol vapor at 300-480℃, silver, copper or silver-copper alloy mesh or particles are used as the catalyst, and acetaldehyde is prepared by oxidation and dehydrogenation of air.
