Product Name:3-Ethoxy-4-methoxybenzaldehyde
CAS Number:1131-52-8
Molecular formula:C10H12O3
Molecular Weight:180.2

In a 3 L dry reaction flask, 157 g of sodium hydroxide was dissolved in 1500 ml of water, 500 g of isovanillin, 120 g of tetrabutylammonium fluoride, and 537 g of ethyl bromide were added, and the reaction was stirred at 25°C for 4 hours. After filtration by suction, an off-white solid powder of 3-ethoxy-4-methoxybenzaldehyde was obtained with a purity of 99.9% and a yield of 96.1%.
