| Abstract: | The myrcene and 1,4-benzoquinone are used as raw materials to synthesize naphthalene catechol derivatives naphthalene-1,4-diol.Using GC-MS,melting point determination,FT-IR,1 H NMR as detection means,the structure of the product is identified as 6-(4-methyl-pent-3-enyl)-5,8-dihydronaphthalene-1,4-diol.Diels-Alder reaction is affected by different type of catalysts,catalyst amount,reaction solvent,reaction temperature,the ratio of raw materials and reaction time.It is concluded that the suitable molar ratio of myrcene to 1,4-benzoquinone is 1 ∶ 1,while the fittest catalyst is ZnCl2,the dosage is 15% of 1,4-benzoquinone.Ethyl acetate is chosen as solvent and the reaction temperature is 80 ℃,reaction time is 10 h.Under this condition,the selectivity and yield of product reached 81.0 % separately. |
| Keywords: | myrcene 1 4-benzoquinone naphthalene-1 4-diol synthetic process |
