     Hydrocondensation of CO-3 C₂H₄-2 H₂ at 190° yields the oil layer, which was separated into components conventionally.  These comprised 2-3% O₂ derivatives (10% in the aqueous layer of catalyzate).  The aldehyde content was 0.9% in the oil and 1.9% in the aqueous layer.  Of these only EtCHO was identified.  Ketones are absent.  The aqueous layer contained 1.5% organic acids, of which 70% was EtCOOH.  The hydrocarbons formed in the reaction represent a very wide boiling range and are a complex mixture of paraffins and olefins containing C₆, C₈, C₅, and C₂ members; the latter probably form by intermediacy of CH₂ radicals, which are believed to be the principal hydrocarbon-forming agency.  The nonparticipation of CO in this reaction is confirmed by lack of condensation of CO with C₂H₄ in the absence of H₂.  Small amounts of PrOH were isolated from the summary reaction product (identified as the 3-nitrophthalate.)
