epichlorohydrin as in example v above to obtain a product solution analyzing for 2 28 meq g total amine 1 45 free 0 13 amine hydrochloride and 0 7 quats a a 1 weight percent aqueous solution on an amines charged basis where aminopolymers were used rather than on an amines salts basis of each chemical was prepared with ph adjustment accomplished by use of concentrated hydrochloric acid b a 30 ml pyrex u00ae test tube equipped with screw top was charged with 23 ml emulsion of 11 5 weight percent bitumen content obtained by in situ steam flooding in tar sand pattern located at ft mcmurray alberta canada c 2 ml wizard lake crude oil was added as diluent and the contents of the test tube were mixed d the contents of the test tube were equilibrated in a 80 u00b0 c oven for 1 2 hours and mixed again e chemical was added to the hot dilute emulsion at 120 ppm treating level f contents of the test tubes were mixed re equilibrated in an oven at 80 u00b0 c for 1 hour and mixed again g after 20 hours of standing at 80 u00b0 c measurements were made on the volume of top and middle layers and the appearance of the aqueous phase was noted samples of some top layers were carefully removed by pipetting and subjected to karl fischer analysis for determination of the water content ph measurements.
