Since the reaction proceeds very smoothly under these conditions, the main products are obtained in high yields, including with a high degree of frequency. Increasing the amount of DB18K6 from 0.001 to 0.004 moll and carrying out the reaction at a temperature of 1000°C for 70 minutes in the system: 1, 2 dimethyl cyclohexane, KOH (0.4 moll), dioxin leads to a gradual increase in the yield of methyl cyclohexane. The maximum yield is achieved with the use of 0.004 moll DB18K6. Secondly, carrying out the reaction at 130°C (against 250°C) excluded the formation of by-products, as well as the products of isomerization and tarification. An organic compound of composition C12H24O6, belonging to the class of cyclic ethers (crown ethers) and having in a single cycle 6 oxygen atoms arranged in a symmetric manner. It is a white hygroscopic crystal with a low melting point. It is widely used as a specific complexing agent for potassium ions K+. Used reducing agents in a homogeneous medium. Restored ketones in boiling xylene or toluene in the presence of ekvimolar amounts of catalysts, which contributed to the increase in solubility. Diglime, dimethoxymethane and dibenzo-18-crown-6 were used as catalysts. The last of them leads to better results, however, due to the occurrence of side condensation reactions, the yields of the target products are mediocre. Solid or oily substances form stable complexes with salts (alkali and alkali-metal) soluble in organic solvent. The most commonly used are 18-cray-6, dibenzo-18-crown-6 and the hydrogenation product of the latter - dicyclohexylene-18-crown-6. Studying the influence of various factors, it was found that when using potassium hydroxide (0.4 moll) in xylene at a temperature of 130°C in the presence of dibenzo-18-crown-6 (DB18K6) (0.0004 moll), the yield of methyl cyclohexane reaches 90 98%.
