ABSTRACT

An improved design of a vacuum distillation apparatus and the procedure for recovering fire accelerants from charred debris is illustrated and described. The recovery of gasoline and fuel oil from sawdust and charcoal is demonstrated with the aid of a G.L.C, analysis of the vacuum distillates obtained. Vapor pressures at various temperatures of petroleum products are illustrated and discussed along with the applicability of this technique.

RÉSUMÉ

L'article décrit et illustre un appareil amélioré servant à la distillation à vide et le procédé utilisé pour révéler la présence d'accélérants d'incendie dans des débris carbonisés. On y démontre comment déceler des vestiges d'essence et de fuel-oil dans de la sciure et du charbon de bois en analysant les distillate par chromatographie de partage. La pression des vapeurs des produits du pétrole à divers degrés de température est discutée et illustrée au cours de l'article. On y démontre également l'applicabilité de la technique.
