2-甲基-1,4-萘醌的合成

Sythesis of the 2-Methyl-1,4-naphthoqueinone

研究了以2-甲基-1-萘酚(MNL)为原料,Ti-MMM-2为催化剂,乙腈为溶剂,用双氧水作氧化剂,合成2-甲基-1,4-萘醌(维生素K3,MNQ)的工艺条件。在最佳工艺条件下,MNQ的收率可达70%。

The catalytic oxidation of 2-methyl- 1 -naphthol （MNL） to 2-methyl- 1,4- ＇naphthoqueinone （MNQ） using aqueous H202 as an oxidant and titanium silicates Ti-MMM-2 as catalysts has been studied. MNQ can be obtain at the yield of 70%.
