Реферат: A continuous process for producing an aldehyde comprising (1) feeding an olefinically unsaturated compound, carbon monoxide, hydrogen and a rhodium-organobisphosphite complex catalyst to a hydroformylation reactor and (2) reacting an olefinically unsaturated compound with carbon monoxide and hydrogen in the presence of a rhodium-organobisphosphite complex catalyst, wherein (a) 1000 part per million vinyl cyclohexene, (b) 25 parts per million butadiene, (c) 25 parts per million of other multi-unsaturated conjugated organic compounds, (d) 100 parts per million water, (e) 500 parts per million peroxide, (f) 2 percent by weight methyl-2-methyl-2-butenoate, (g) 100 parts per million primary alcohol, (h) 100 parts per million oxygen.
