1-Butanol → Butyl Methacrylate

Participants

Reaction Steps

A 148.2g (2.0 mols) amount of n-butanol, 400.5g (4.0 mols) of methylmethacrylate, 0.5g of hydroquinonemonomethyl ether and 2.45g (0.025 mol) of concentrated sulfuric acid were added to a flask to conduct a reaction in the same manner described in Example 1. The reaction was carried out for 6 hours. The reaction results obtained were an 89.9% conversion of n-butanol and an 88.2% yield of n-butyl methacrylate. However, it was found by gas chromatography that a high boiling point by-product was present and 0.004 mol of methacrylic acid (2740 ppm. on n-butyl methacrylate) was produced as a by-product.
