Colorimetric determination of carbon monoxide in air by an improved palladium chloride method.
The decrease in palladium chloride can be determined calorimetrically (2) and by means of iodometric titration (3). Christman, Block, and Schultz (4) determined CO in air by transferring gas mixtures to flasks at pressures of about 0.5 atmosphere, containing known quantities of PdC12. After 6 to 24 hours the PdClz which remained was converted to PdIz by the addition of excess KI, the pinkish re...
متن کاملPalladium(II)-catalyzed copolymerization of styrenes with carbon monoxide: mechanism of chain propagation and chain transfer.
A mechanistic interpretation of the [(1,10-phenanthroline)Pd(CH(3))(CH(3)CN)](+)[BArF](-) (1a) and [(2,2'-bipyridine)Pd(CH(3))(CH(3)CN)](+)[BArF](-) (1b) (BArF = 3,5-(CF(3))(2)-C(6)H(3)) catalyzed perfectly alternating copolymerization of styrenes with CO is reported. The copolymerization in CH(2)Cl(2) or chlorobenzene has been found to be first order in styrene and inverse first order in CO co...
