New petrochemical compositions for use in the coal industry
Autor: E. V. Surov, O. G. Safiev, D. O. Safieva
Publikováno v: Solid Fuel Chemistry. 42:382-383
Various aspects of the use of antifreezing agents in the coal industry are considered. It has been found that, unlike previously proposed compositions, these agents can be prepared based on the products of a single process, the vacuum distillation of

Telomerization of ethylene with dimethylacetal
Autor: A. B. Terent'ev, U. B. Imashev, O. G. Safiev
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 28:2313-2316
1. Telomerization of ethylene with acetaldehyde dimethylacetal gives three series of products: acetals CH3CH(OCH3)OCH2(CH2CH2)nH (n=1-3), acetates CH2CO2CH2(CH2CH2)nH (n= 1 and 3), and ketones CH2CO(CH2CH2)nH (n=1-3). 2. To account for the formation

1,5- and 1,9-migration of hydrogen during telomerization of propylene with dimethyl acetal
Autor: O. G. Safiev, U. B. Imashev, A. B. Tarent'ev
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 29:1134-1137
1. The telomerization of propylene with dimethyl acetal leads to the formation of two series of telomers, and specifically acetals and acetates. 2. The formation of the acetates is due to rearrangement of the growing radicals with a 1,5- and 1,9-migr

Radical telomerization of 1-hexene by 1,4-dioxane
Autor: S. S. Zlotskii, D. E. Kruglov, D. L. Rakhmankulov, O. G. Safiev
Publikováno v: Chemistry of Heterocyclic Compounds. 19:951-953
It was established that telomer homologs of a number of 2-alkyl-1,4-dioxanes are formed as a result of radical telomerization of 1-hexene by 1,4-dioxane. The partial chain-propagation constants of the process were calculated, and the mass spectra of

Telomerization of ethylene with ethylal
Autor: U. B. Imashev, A. B. Terent'ev, D. L. Rakhmankulov, O. G. Safiev, S. S. Zlotskii
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 27:2487-2489
The telomerization of ethylene with ethylal goes at theα-C-H bond of the ethoxyl group to give the telomers CH2(OC2H5)OCH(CH3)(CH2CH2)nH·

Autor: L. N. Zorina, D. L. Rakhmankulov, O. G. Safiev
Publikováno v: Chemistry of Heterocyclic Compounds. 25:261-263
When 5,6-benzo-1,4-dioxane was reacted with N,N-dialkylchloramines in the presence of FeSO4 at 10–20‡C in a solution of acetic and sulfuric acids, 6-(N,N-dialkylamino)benzo-1,4-dioxanes and 6-chloro- and 6,7-dichloro-benzo-1,4-dioxanes were obtai
