3-Methoxybenzaldehyde - Uses and synthesis methods
introduction
3-Methoxybenzaldehyde is a colorless or light yellow oily liquid. Solubility: insoluble in water, soluble in alcohol, ether, benzene.
application
3-methoxybenzaldehyde is widely used in chemical and chemical fields as chemical raw materials, organic intermediates and spices.
Preparation
The molar ratio of nitric acid to m-methoxybenzyl methanol is 1.5, and the mass ratio of water to m-methoxybenzyl methanol is 1; reduce the two bottles to below 5 degrees and then add m-methoxybenzyl methanol, start stirring, then add the pre-prepared nitric acid solution, after adding, the system returns to room temperature, TLC and liquid phase monitor the reaction, after about seven hours, add sodium hydroxide solution to the system, wash with water and saturated salt water, and dry with anhydrous magnesium sulfate. Decompression desolysis gives the product.
production method
It is obtained by the reaction of m-hydroxybenzaldehyde and dimethyl sulfate.
