The carbonylation of formaldehyde with carbon monoxide was carried out over two kinds of cation-exchange resins as solid acid catalysts. Effects of reaction conditions on the catalytic performance were studied. From 1 H NMR, 13 C NMR, IR, and GC-MS analyses of the products obtained, it was found that 1, 3-dioxolan-4-one (1, 3-DOX-4) is selectively produced over the cation-exchange resins. The carbonylation of formaldehyde with ...
