1-Butanol → Butyl Acrylate

Participants

Reaction Steps

The conditions were the same as those described in Example 1, but the reaction temperature was increased from 120° to 130° C. The reactor was charged with 310 g/h of a mixture consisting of 32.7 weight % of acrylic acid, 57.2 weight % of n-butanol and 10.1 weight % of butylacrylate. 83.2% of the acrylic acid underwent conversion. 310 g of reaction product consisting of 175 g of butylacrylate, 90 g of n-butanol, 21 g of water, 17 g of acrylic acid and 7 g of residue was discharged. 143 g/h of pure butylacrylate free from dibutylether was obtained. This corresponded to a yield of 95.7%, based on the acrylic acid which underwent conversion. The catalyst performance was 923 g of butylacrylate per kg of catalyst per hour.
