氯铬酸甲胺/硅胶氧化1-萘甲醇制备1-萘甲醛

摘要

This paper discussed a new method for synthesizing 1-naphthalene carboxyaldehyde (1-NA) by oxidizing 1-naphthylmethanol with methylamine chlorochromate supported by silicon dioxide. Through investigating the effects of temperature, concentration of 1-naphthylmethanol, amount of oxidant, and solvents, it was found that 1-NA can be selectively obtained at room temperature. The selectivity reached 90.2%.%采用一种新型氧化剂氯铬酸甲胺/硅胶(MCC/硅胶)氧化1-萘甲醇制备1-萘甲醛，考察了温度、溶剂、氧化剂用量和1-萘甲醇浓度对反应的影响，结果发现MCC/硅胶可在室温、高选择性地将1-萘甲醇氧化为1-萘甲醛，选择性达90.2%.
