8.重質炭化水素溶液の拡散係数・会合体サイズ評価における濃度依存性

抄録

Diffusion coefficients of some petroleum asphaltenes and resins in chloroform solution were measured by using pulsed-gradient spin-echo ^1H NMR. Effects of asphaltene type and concentration were studied. From the experimental results of diffusion coefficients, mobilities and the aggregates sizes of samples were estimated.
