Preparation method of dimethyl 2, 6-naphthalate

The invention discloses a preparation method of dimethyl 2, 6-naphthalate. Specifically, the preparation method of the dimethyl 2, 6-naphthalate disclosed by the invention comprises the following steps: carrying out esterification reaction on 2, 6-naphthalic acid and methanol under a pressurization condition in the presence of a catalyst, and filtering without further purification to obtain the dimethyl 2, 6-naphthalate, wherein the mass ratio of the methanol to the 2, 6-naphthalic acid is (3: 1)-(25: 1), the reaction temperature ranges from 100 DEG C to 150 DEG C. According to the preparation method disclosed by the invention, the operation is simplified, the yield of the dimethyl 2, 6-naphthalate is improved, and meanwhile, the purity of the dimethyl 2, 6-naphthalate is maintained.

Sequential Acetalization-Pyrolysis of α-Acetylcinnamates and α-Acetylbenzalacetones. A Method for the Generation of 2-Carbonyl-Subsituted Naphthalenes

Substituted 2-acetonaphthones and 2-naphthoate methyl esters can be generated from benzaldehydes in a sequence of three reaction steps.Knoevenagel condensation of a benzaldehyde with 2,4-pentandione of methyl acetoacetate yields α-carbonyl-substituted benzalacetones.The α-carbonyl-substituted benzalacetones are then cyclized to generate the α-carbonyl-substituted naphthalenes by a sequential acetalization with trimethyl orthoformate followed by subsequent pyrolysis of the dimethyl acetal either in the vapor phase at 475 deg C or by being heated in boiling 1-methylnaphthalene. 2-Acetonaphthones are obtained when 2,4-pentanedione is used and 2-naphthoate methyl esters are obtained from methyl acetoacetate.
