The invention discloses a green synthesis method of acetal or ketal compounds, which uses a carbonyl compound as a raw material, uses a hydrogen-carrying compound as a catalyst, and then adds alcohols to react to generate acetal or ketal compounds. The synthesis method is simple, high conversion rate and yield, safe and stable, low toxicity, easy to operate; the catalyst used is simple to prepare, cheap and easy to obtain; the reaction process is mild and efficient, the product is easy to separate and purify, and has a wide range of substrate applications. It can be used in the synthesis of acetal and ketal spices, and has potential industrial application value. |
