3-hydroxyl-2-hydroxi is a kind of products in Naphthol AS. The main functional group of 3-hydroxyl-2-hydroxi is amide linkage. There are a great number of methods of the known synthetic amide linkage. On the condition of using 2,3-acid and N-(3- aminopropyl groups)- morpholine as materials, xylene as solvents and phosphorus trichloride as catalysts, this compound is synthetized by adopting acid method and sodium salt method. This paper primarily studies the relation between reaction time and yield, and also makes a relevant comparison between the two methods, whose aim is to determine the best reaction time, optimize the production technology, improve yield of reaction and lay a foundation of achieving mass production.

3-hydroxyl-2-hydroxi is one kind of Naphthol AS products. The main functional group of 3-hydroxyl-2-hydroxi is amide linkage. There are many ways to produce synthetic amide linkage. This compound is synthetized  through the acid method and the sodium salt method by taking 2,3-acid and N-(3- aminopropyl groups)- morpholine as raw materials. And in the process, the xylene is used as solvents and the phosphorus trichloride is used as catalysts. This paper primarily studies the relationship between reaction time and related productivity. A comparison between the two methods has also been conducted in the paper, whose aim is to choose the best reaction time, optimize the production technology, improve productivity and lay a foundation for mass production.
