一些多环芳烃的蒸气压采用流出法测量。根据压力的温度依赖性，计算了以下烃的升华热 (ΔH kcal/mol) 和熵 (ΔS° cal/mol·deg)：1,2-苯并蒽 (ΔH=22.8; ΔS°=44.8)、并四苯 (29.8; 43.3)、屈 (28.1; 43.0)、苯并菲(25.6; 33.9)、3,4-苯并菲(25.4; –) 对三联苯(28.3; 47.9)、1,12-苯并苝(30.0; 40.7)、3,4-苯并四吩(32.6; 45.9)、1,2,5,6-二苯并蒽(33.9; [0100] 并五苯(37.7；48.9)、五苯烯(33.5；45.9)、晕苯(30.7；36.9)、1,2,4,5-二苯并芘(32.9；48.3)、1,2,6,7-二苯并芘(35.1；45.6)， 1,3,5-三苯基苯(34.0；55.6)、四苯并萘(33.9；47.4)、异紫蒽A(52.2；54.6)、紫蒽A(46.8；48.1)、紫蒽B(36.7；38.0)和四苯并苝(28.2；44.7)。紫蒽 B、四苯并苝和四苯并萘的较小 ΔH 值可能反映了非共面的存在...
The vapour pressure of some polycyclic aromatic hydrocarbons was measured by means of the effusion method. From the temperature dependence of the pressure, the heat of sublimation (ΔH kcal/mol) and the entropy (ΔS° cal/mol·deg) were calculated for the following hydrocarbons: 1,2-benzanthracene (ΔH=22.8; ΔS°=44.8), tetracene (29.8; 43.3), chrysene (28.1; 43.0), triphenylene (25.6; 33.9), 3,4-benzophenanthrene (25.4; –) p-terphenyl (28.3; 47.9), 1,12-benzperylene (30.0; 40.7), 3,4-benztetraphene (32.6; 45.9), 1,2,5,6-dibenzanthracene (33.9; 49.3), pentacene (37.7; 48.9), picene (33.5; 45.9), coronene (30.7; 36.9), 1,2,4,5-dibenzpyrene (32.9; 48.3), 1,2,6,7-dibenzpyrene (35.1; 45.6), 1,3,5-triphenylbenzene (34.0; 55.6), tetrabenzonaphthalene (33.9; 47.4), isoviolanthrene A (52.2; 54.6), violanthrene A (46.8; 48.1), violanthrene B (36.7; 38.0) and tetrabenzoperylene (28.2; 44.7). The small values of ΔH for violanthrene B, tetrabenzoperylene and tetrabenzonaphthalene may reflect the existence of the non-coplan...
