| Abstract: | Complexing in the HNO3-CH2Cl2 system was confirmed tensimetrically. The kinetics of nitration of wood cellulose by the HNO3-CH2Cl2 mixture were investigated. A large part of the cellulose is nitrated in a first fast reaction in comparison to the HNO3-H2SO4 mixture with the same concentration of HNO3. The rate of the process is determined by the rate of diffusion of the HNO3, the rate of the process decreases more rapidly in the case of HNO3-CH2Cl2 than in the HNO3-H2SO4 mixture, which is probably due to the effect of CH2Cl2 on the diffusion coefficient of HNO3.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2445–2450, November, 1989. |
