PHOTOCHEMICAL DECOMPOSITION OF 3-CHLORO-CROTON ALDEHYDE TOSYLHYDRAZONE SODIUM SALT
The low temperature photochemical decomposition of 3- chloro-croton aldehyde tosylhydrazone sodium salt in tetrahydrofuran results in the formation of 3- chloro- 3- methyl cyclopropene and 5- chloro- 5- methyl- pyrazolenine respectively. In the presence of moisture, the photohydrated compound 3 was obtained as one of the products
متن کاملPolymerization of propylene in a minireactor: Effect of polymerization conditions on particle morphology
Gas phase polymerization of propylene was carried out in a semi-batch minireactor using a commercially supported Ziegler–Natta (ZN) catalyst. The influence of variables including monomer partial pressure, external electron donor, reaction temperature and time on the particle morphology and size distribution was investigated. Generally, more uniform fragmentation and particle densities were obta...

dehydrogenases. The same effects obtained when e N A D + is bound to binary complexes confirm the transfer of the coenzyme to a more hydrophobic environment, but also indicate that the coenzyme is bound to ODH in an open conformation, as found in other dehydrogenases. The high degree of conformational rigidity of bound coenzyme were deduced on the one hand from the negligible temperature coeffi...
متن کاملAldehyde dehydrogenase. Covalent intermediate in aldehyde dehydrogenation and ester hydrolysis.
4-trans-(NN-Dimethylamino)cinnamaldehyde (an aldehyde, DACA) and 4-trans-(NN-dimethylamino)cinnamoylimidazole (an amide, DACI) have been shown to be substrates for human aldehyde dehydrogenase (EC 1.2.1.3) which form chromophoric covalent intermediates. The spectra of covalent intermediates from both the cytoplasmic (E1) and mitochondrial (E2) isoenzymes derived from DACA and DACI were compared...
متن کاملSynthesis of Polyamide 6 by Anionic Polymerization of ε-Caprolactam in an Internal Mixer: Effect of Polymerization Reaction Time
The main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. The reaction time and the rheological properties of samples during the polymerization were studied. The samples were characterized by Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimeter (DSC) and FT-IR spectrometer. The melt flow behavior and ...
