Pseudomonas being attached HN-72 and the refinement mannered null 2 formyl 6 naphthoic acid of the 2,6

摘要

It regards the method of refining 2,6 naphthalene di-carboxylic acid in high purity making use of the new microbe and this. The aforementioned microbe the Pseudomonas being attached which is separated from the soil (Pseudomonas sp.) being the HN 72 strain, making 2,6 dimethyl naphthalene oxidize, has the ability to convert the 2 formyl 6 naphthoic acid which is the impurity which naphthalene which is formed di-carboxylic acid (crude naphthalene dicarboxylic acid) is included roughly to 2,6 naphthalene di-carboxylic acid. The Pseudomonas being attached HN 72 strain converting the 2 formyl 6 naphthoic acid which is the impurity which is included in naphthalene di-carboxylic acid roughly to 2,6 naphthalene di-carboxylic acid, although it produces the 2,6 naphthalene di-carboxylic acid of high purity at high yield, is an effect which is superior. Selective figure It is not
