摘要: Compounds useful for associating with nanoparticle or microparticle emulsions to obtain magnetic resonance images permit control of the relaxivity of the signal and readily associate with the particulate components. The compounds are conveniently prepared from achiral derivatives of chelating moieties.

摘要: 3,3-Dimethylbutanal is prepared from 3,3-dimethylbutanol. Intermediate 3,3-dimethylbutanol is obtained by reacting ethylene, isopropylene and a mineral acid to produce a 3,3-dimethylbutyl ester which is hydrolyzed to the alcohol. The hydrolysis step is effectively carried out by reactive distillation. Alternatively, 3,3-dimethylbutanal is prepared from 3,3-dimethylbutanol obtained by reduction of the corresponding carboxylic acid or 1,2-epoxy-3,3-dimethylbutane, or by hydrolysis of 1-halo-3,3-dimethylbutane. Fixed bed gas phase and stirred tank liquid phase processes are provided for converted 3,3-dimethylbutanol to 3,3-dimethylbutanal by catalytic dehydrogenation.
