2,6-NAPHTHALENEDICARBOXYLIC ACID - Reference Information
| LogP | 2.22 |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | this product is used to manufacture polyester fiber and f-grade insulating material with high strength and excellent dyeing performance. it is an important monomer of high performance PEN, PBN, liquid crystal polymer (LCP) and polyurethane resin, and is also an important raw material for medicine and fine chemicals. |
| Production method | One method is to synthesize NDA/NDC through Henkel reaction from the mono-or binary carboxylate of naphthalene; The other is to first synthesize 2,6-position substituted naphthalene that can be used for oxidation, and then oxidize to NDA, namely 2, 6-dialkylnaphthalene method and 2-alkyl-6-acylnaphthalene method. At present, the only industrialized (including semi-industrialized) production methods in the world are the o-xylene DMN method of BP Amoco in the United States, the 2-methyl-6-acetylnaphthalene method of MGC in Japan and the 2, 6-diisopropylnaphthalene oxidation method of Japan's Sumijin Chemical Company. |
