| titleOfInvention | Method for preparing 2-amino-3,5-dibromobenzaldehyde having high purity and yield |
| abstract | The present invention relates to a method for preparing 2-amino-3,5-dibromobenzaldehyde of high purity and high yield, wherein 2-amino- of Formula 2 is used under a mixed solvent comprising a polar solvent, an organic-inorganic alkali, an antioxidant, and water. Using 3,5-dibromobenzoic hydrazide as a starting material, and reacting by mixing a ketone compound, an oxidizing agent and water on the basis of the starting material, and performing filtration, washing, and solvent recovery process to achieve high yield and high purity. It relates to a method for preparing 2-amino-3,5-dibromobenzaldehyde of the formula (1). The method according to the present invention improves the manufacturing process of 2-amino-3,5-dibromobenzaldehyde, reduces the amount of by-products produced, improves the quality and saves manufacturing costs, thus making 2-amino-3,5- of high yield and high purity. Dibromobenzaldehyde can be prepared.n n n Chemical Formula 1 Chemical Formula 2 |
