This <str<strong>on</strong>g>distributi<strong>on</strong></str<strong>on</strong>g> model allows from incomplete distillati<strong>on</strong> data the entire distillati<strong>on</strong><br />
curve <str<strong>on</strong>g>of</str<strong>on</strong>g> a <str<strong>on</strong>g>crude</str<strong>on</strong>g> oil to be built regardless <str<strong>on</strong>g>of</str<strong>on</strong>g> the method used for measuring <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />
distillati<strong>on</strong> characteristics. On this base the entire distillati<strong>on</strong> curve can be c<strong>on</strong>structed<br />
by the use <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>ASTM</strong> D-<strong>86</strong> method for measuring <str<strong>on</strong>g>of</str<strong>on</strong>g> the evaporate boiling up to<br />
300ºC. An attempt to apply the Riazi-Daubert C<strong>on</strong>versi<strong>on</strong> Method, the Daubert<br />
C<strong>on</strong>versi<strong>on</strong> Method <strong>and</strong> the Edmister C<strong>on</strong>versi<strong>on</strong> Method for c<strong>on</strong>verting <strong>ASTM</strong> D-<br />
<strong>86</strong> into <strong>TBP</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> the investigated <str<strong>on</strong>g>crude</str<strong>on</strong>g> <str<strong>on</strong>g>oils</str<strong>on</strong>g> was found to be unsuccessful. Therefore<br />
a new method for c<strong>on</strong>versi<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>ASTM</strong> D <strong>86</strong> distillati<strong>on</strong> to <strong>TBP</strong> distillati<strong>on</strong> applicable<br />
for <str<strong>on</strong>g>crude</str<strong>on</strong>g> <str<strong>on</strong>g>oils</str<strong>on</strong>g> should be developed.<br />
