Заглавие : Critical Point Measurements for Five n-Alkylcyclohexanes (C6 to C10) by the Pulse-Heating Method Место публикации : Journal of Chemical & Engineering Data. - 2003. - Vol.48, №5. - С. 1137-1140 Ключевые слова (''Своб.индексиров.''): alkylcyclohexanes--carbons --methods of lydersen Аннотация: This paper presents experimental critical temperatures and pressures of five n-alkylcyclohexanes C6H11CnH2n+1 with the number of carbons in the side chain n = 0, 1, 2, 3, or 4. The method of pulse heating of a wire probe immersed into the liquid under study has been used. Residence times are from (0.01 to 1) ms. Equations for the correlation of the critical temperatures and pressures of n-alkylcyclohexanes with the number of carbon atoms in the side chain, normal boiling point, and molar mass have been obtained. The experimental critical constants of alkylcyclohexanes have been compared with the values calculated by the group-contribution methods of Lydersen, Joback and Reid, and Constantinou and Gani Доп.точки доступа: Popov, A.
