摘要:
Quartz Crystal Microbalance (QCM) was used to study heterophase reactions of hydrazine vapor with solid copper(I) pi-complexes Cu2Cl2 (.) DVB, CuCl (.) AA, (HDAA)CuCl2, and Cu(HMA) (.) H2O (where DVB is CH2=CH-C6H4-CH=CH2, AA is CH2=CH-CH2-NH2, HDAA is (CH2=CH-CH2)(2)NH2+, and HMA is the HOOC-CH=CH-COO-. It was found that all the complexes can add hydrazine reversibly. However, in contrast to ionic complexes, molecular complexes gradually decomposed while reacting with the vapor of N2H4. The kinetic parameters such as the rate constants of forward and reverse heterophase reactions were determined. Complex Cu(HMA) (.) H2O was found to be most sensitive to the vapor of N2H4.
