    Abstract: A process for the preparation of 2,3-dimethylpentanal which comprises contacting 3-methyl-2-pentene with carbon monoxide and hydrogen in the presence of a rhodium carbonyl compound as catalyst. Rhodium carbonyl catalysts are those which contain only rhodium and carbon monoxide and in certain cases, also hydrogen. Especially contemplated are non-phosphine containing rhodium carbonyl catalysts.

    Abstract: An incinerator has a lower combustion portion preferably equipped with a burner and an upper afterburning portion which can be swung off the lower portion. This upper portion has an upper outlet mouth. A chimney extends alongside the portions and has a lateral flue which opens just above the upper outlet mouth. A collar on the flue controls the amount of air let in at the gap between the flue''s end and the mouth and this collar can be lifted also to swing out the upper afterburning portion for loading the combustibles into the burning chamber. A flap on the chimney below where the flue is connected is biased closed by a weight and, on excessive draft, opens to control this draft.
