                  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.
