Abstract
Acrylic esters are prepared by dissolving acetylene in a solvent and reacting it with carbon monoxide and a C1-12 aliphatic, monohydric alcohol in the presence of a catalyst known to catalyse the reaction at 220-270 DEG , preferably 240-250 DEG C., and 2000-4500, preferably 2500-3500 p.s.i. The reactant alcohol is the preferred solvent. Other suitable solvents include dioxan, tetrahydrofuran and water. The reaction may be carried out batchwise or continuously. The alcohol may be primary, secondary or tertiary and is preferably used in slight excess. Generally 0.5 to 5 per cent by weight based on the alcohol of a catalyst such as a nickel halide is used. In examples: (1) methyl acrylate is prepared by dissolving acetylene in methanol and then reacting with carbon monoxide using a nickel bromide catalyst; by-products are mainly dimethyl ether; (2) 2-methylhexyl acrylate is similarly prepared from 2-methylhexanol.
