摘　　要：The process conditions such as feed ratio, catalyst, reaction temperature and pressure, and the process of o-xylene/butadiene route, p-xylene/butadiene route, toluene/MTBE raffinate route and naphthalene alkylation route for 2,6-dimethylnaphthalene (2,6-DMN) were described in this article. The process conditions and process of freeze crystallization, high pressure crystallization, adsorption and crystallization/adsorption combined for 2,6-DMN purification were discussed, and the production costs of 2,6-DMN from o-xylene/butadiene route, p-xylene/butadiene route and naphthalene alkylation route were also analyzed.The process conditions such as feed ratio, catalyst, reaction temperature and pressure, and the process of o-xylene/butadiene route, p-xylene/butadiene route, toluene/MTBE raffinate route and naphthalene alkylation route for 2,6-dimethylnaphthalene (2,6-DMN) were described in this article.
