 1357.    HARDY, D. V. N.  Interaction of Olefins, Carbon Monoxide, and Steam.  Jour. Chem. Soc., 1936, pp. 364-365; Chem. abs., vol. 30, 1936, p. 3771.

        Passage of a mixture of 1 volume C₂H₄ and 4 volumes CO under a pressure of 150 atm. at a rate of 40 l. compressed gas/hr. through 350 gm. 87% H₃PO₄ at 290°-300° gives 500 gm. product containing 16.5 gm. high-boiling hydrocarbons, 37 gm. EtOH, and a solution of Na salts containing EtCO₂H.  For every molecule C₂H₄ converted into acid, approximately 3 were hydrated and 2 polymerized.  C₃H₆ and CO at 200° and 20 atm. (850 gm. C₃H₆ during 6 hr.) give 546 gm. of an upper layer (41% free acid) and 284 gm. of a lower layer (6.2% free acid).  After refluxing 2 hr. with NaOH there were isolated 88.4 gm. volatile and 01.3 gm. nonvolatile hydrocarbons, 3 gm. Me₂CHOH, 10.5 gm. acids, boiling 150°-159°, and 173 gm. residue, Me₂CHCO₂H was identified.  Iso-C₄H₈ (640 gm.) gave 10.6 gm. hydrocarbons, 32.5 gm. acid, boiling 160°-168°, 23.1 gm. acid, boiling 168°-190°, and 24.2 gm. residue.  Esterification gave 32.8% of Me pivalate and 22.6% MeEtCHCO₂Me.  Homologs also were present but not identified.
