| abstract | Hydroxypivalic esters, in particular the cyclooctylmethyl, n-butyl, n-hexyl, n-octyl, n-lauryl, hexahydrobenzyl, and methyl esters, are prepared by hydroformylating a methacrylic ester in the presence of a rhodium-containing catalyst at between 80 DEG and 120 DEG C. and a pressure of at least 100 atmospheres, and then hydrogenating the resulting hydroformylation product to the ester. Organic trivalent phosphorus compounds such as trialkyl phosphites, triarylphosphines, trialkyl phosphines, phospholines, phospholanes and other 6-, 7- and 8-membered phosphocycloalkanes may be included in the first stage in a proportion of from 0.1 to 20% and favour the formation of a -formylated products. Rhodium sesquioxide is preferred, but salts or metal may be used as the catalyst. A molar ratio of carbon monoxide to hydrogen between 2:1 and 1:4 may be used and an inert solvent may be present. Hydrogenation catalyst such as Raney nickel or cobalt and copper chromite may be used and the rhodium need not be removed until the final purification. |
