1-Butanol → Butyl Methacrylate

Participants

Reaction Steps

74.1 g (1.0 mole) of n-butanol, 250.2 g (2.5 moles) of methyl methacrylate, 0.25 g of hydroquinonemonomethyl ether and 2.45 (0.025 mole) of concentrated sulfuric acid were added to a flask to conduct a reaction in the same manner as in Example 1. The reaction was carried out for 6 hours. The reaction results were 96.5% conversion of n-butanol and 91.2% yield of n-butyl methacrylate. However, it was found by gas chromatography that a high boiling point by-product was present and 0.004 mole of methacrylic acid (2660 ppm. based on n-butyl methacrylate) was produced as a by product.
