                  Rohm & Haas Co. announced the availability of 6 new chemicals derived from the Oxo process.  A pilot plant has been constructed for preparing aldehydes catalytically from olefins CO and H₂.  The olefin first chosen for the process is disobutylene, which reacts by the Oxo process to give only 1 isomer.  The carbonyl group becomes attached to the terminal C to produce 3,5,5-trimethylhexaldehyde.  The 6 chemicals now available are derived from this nonyl aldehyde:  Nonaoic acid, nonylamine, nonyl aldehyde cyanohydrin, a-hydroxydecanoic acid, octadecenyl aldehyde, and octadecyl alcohol.  Some potential uses for these products are enumerated.
