Under these conditions the conversion of benzoic acid achieves nearly 100%, but the selectivity to benzaldehyde decreases, while that to toluene and benzene increases. In this range of temperatures, the reaction proceeds too far, due to a very high concentration of vacancies. Besides the redox ...

This has been found to be true with p-nitrophenol and nitrobenzene; however, with benzaldehyde and phthalimide the increase in solubility overbalances the change of dielectric constant and the reduction efficiency is increased (108). Other workers (358) have pointed out the importance of the ...
a manual transmission and a final reduction gear unit that can exert very excellent low friction characteristics to sliding surfaces present under various applications, and, in particular, that have more excellent low friction characteristics than that of a combination of an existing steel material and...

Scheduling experiments indicate that benzaldehyde must be present immediately before addition of, or simultaneously with, cis-DDP for optimal reduction of cell inactivation. Benzoic acid, benzyl alcohol or the protein synthesis inhibitor cycloheximide did not reduce the inactivating effect of cis-DDP. ...
The invention discloses the method of preparing benzaldehyde with benzene carbonic acid. The method comprises the following steps: 1. using coprecipitation method to prepare accelerant pioneer containing Zn, roasting at the condition of air or nitrogen, getting accelerant with ZnO; 2. using benzene ...
