在283.15,28815,293.15和29815K下,研究了苯-苯、苯-甲烷、甲烷-甲烷在不同比例的H2OTBA混合溶剂中二聚过程的流水相互作用.结果表明,在富水区苯-苯、苯-甲烷、甲完-甲烷成对过程的流水相互作用随x(TBA)的增加光增强后减弱,并且在X(TBA)约为0.06处出现了疏水相互作用极强点.这与H2O-TBA在富水区形成笼合物结构密切相关;在相同条件下,苯-苯、苯-甲烷、甲烷-甲烷成对过程表现出来的流水相互作用相差较大,而且其流水相互作用的强弱随溶剂结构变化的敏感程度明显不同.这说明流水相互作用不仅与溶质的结构性质以及溶剂的结构和组成有关,还和溶质在聚集前后与溶剂接触面积的差别密切相关.
Under 283.15,28815,293.15 and 29815K, the flow-water interaction of benzene-benzene, benzene-methane and methane-methane in the dimerization process of H2OTBA with different proportions was studied. The results show that the water-water interaction of benzene-benzene, benzene-methane and methyl-methane-methane pairs in the water-rich area decreases with the increase of x (TBA) light intensity and decreases at X (TBA) of about 0.06 There is a strong point of hydrophobic interaction. This is closely related to the formation of the clathrate structure in the water-rich region by H2O-TBA. Under the same conditions, the water-water interaction exhibited by the benzene-benzene, benzene-methane and methane-methane paired processes is quite different, The intensity of action varies significantly with the solvent structure. This shows that water-water interaction is not only related to the structural properties of solutes and the structure and composition of the solvents, but also to the differences of solute contact area before and after the solutes are aggregated.
