نویسندگان: ثبت نشده
چکیده مقاله:
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

PHOTOCHEMICAL DECOMPOSITION OF TpBU
Irradiation of the dinucleotide TpBU at all wavelengths from 240 to 295 m/u produces a debrominated photoproduct and two minor products. The main compound has an absorption maxi mum exactly at the same wavelength as the parent compound, but with approximately half the value of the extinction coefficient. It cannot be reverted by short wavelengths, such as 240 m/j,. Consistent with our observat...
متن کاملPhotochemical Degradation of Chloro-biphenyls (PCBs)*
Polychlorinated biphenyls (PCBs) are stable towards oxidation, hydrolysis and other chemical reactions which conceivably occur in the environment. Although there is little direct evidence available, it is generally assumed that PCBs, particularly those with a high chlorine content, are also quite resistant to metabolic change. Over the past years photochemical degradation was shown to be a poss...
متن کاملAn ab initio study of the photochemical decomposition of 3, 3-dimethyldiazirine
Photochemical decomposition of 3,3-dimethyldiazirine (DMD) has been computationally investigated by using high-level ab initio calculations in conjunction with the 6-31G and cc-pvdz basis sets. The geometries of minima and transition states, as well as conical intersection points in the seam of crossing of two surfaces, have been optimized with the complete active space self-consistent field (C...
متن کاملOscillatory photochemical decomposition of tetrathionate ion.
When subject to illumination, tetrathionate ion decomposes in an oscillatory fashion with a period of about 1 h to yield products identified as colloidal sulfur and trithionate ion. This system represents the first experimental example of a stirred, batch photochemical oscillator. A simple model consisting of four reaction steps and four adjustable rate parameters gives good agreement with the ...
متن کاملDecomposition of Oxalate Precipitates by Photochemical Reaction
A photo-radiation method was applied to decompose oxalate precipitates so that it can be dissolved into dilute nitric acid. This work has been studied as a part of partitioning of minor actinides. Minor actinides can be recovered from high-level wastes as oxalate precipitates, but they tend to be coprecipitated together with lanthanide oxalates. This requires another partitioning step for mutua...
