Могут быть использованы как синтетические, так и -нефт ные циклопарафины.(C6OH) 34-H20 + 5NO According to the above, the authors propose to obtain fatty acid dibasic acids and nitrocycloparaffins by reacting nitrogen dioxide with cycloparaffins in the presence or absence of substances capable of regenerating nitric oxide into dioxide, such as oxygen, nitric acid, and so on. Both synthetic and - oil cycloparaffins can be used.

SU435239A1 (en) | A method for producing quinoline alkyl derivatives. The invention relates to a method for producing quinoline alkyl derivatives of the general formula where RI is alkyl; R2 is hydrogen or alkyl, and alkyl RI contains one carbon atom more than alkyl Rs, which are used in the chemical industry. Known methods for producing alkyl derivatives of quinoline by reacting anilines with carbonyl-containing compounds (for example, aldehydes, ketones) in the presence of various condensates , their and yush oxide, their agents require the use of hard-to-reach starting materials. The purpose of the invention — to improve the process technology — is achieved by the fact that a mixture of nitrobenzene and aliphatic alcohol of the general formula ROH, where R is Cz — Ce-alkyl, passed through an industrial vanadium catalyst (B-3) at 320–360 ° C, followed by isolation of the target product by known methods.5 Irimer 1. Synthesis of 2-methylquinoline (quinaldine). A mixture of 13 ml of nitrobenzene and 14 ml of ethyl alcohol is passed through a B-3 vanadium catalyst heated to 320 ° C, but partially activated by hydrogen for 1 hour at 350–380 ° C. An oily layer is separated from the catalyzate consisting of two layers, distilled, and 4.6 ml (35%) quinaldine are obtained, i.e. bale. 246-249 ° C, so pl. picra-15 and 191–192 ° C. Found,%: N 9.92; 10,13.CioHgN. Calculated,%: N 9.79. In Examples 2-5, tabulated, 20 experiments were carried out, as in Example 1, using in each case 13 ml of nitrobenzene and different amounts of alcohols and skips the reaction mixture is heated to a certain temperature vanadium catalyst B-3. 25 The results are shown in the table. | |
