Abstract

with R1, R2, R3, and R4 each being an organic group. A further use as a viscosity reducing agent in diluted bitumen is also disclosed.

Claims

exact text as granted — not AI-modified
1 . A method of reducing friction of a hydrocarbon fluid in a motor or a pipeline, comprising adding to the hydrocarbon fluid a compound comprising an aromatic core of one or more aromatic rings, and two or more amide branches distributed about the aromatic core, each of the two or more amide branches having one or more organic groups. 
     
     
         2 . The method of  claim 1  in which each of the amide branches is connected to the aromatic core via a carbon-carbon or carbon-nitrogen bond. 
     
     
         3 - 4 . (canceled) 
     
     
         5 . The method of  claim 1  in which the two or more amide branches are three or four amide branches. 
     
     
         6 . The method of  claim 1  in which each organic group is an alkyl group. 
     
     
         7 - 8 . (canceled) 
     
     
         9 . The method of  claim 1  in which the aromatic core is benzene. 
     
     
         10 - 13 . (canceled) 
     
     
         14 . The method of  claim 1  in which the aromatic core is naphthalene. 
     
     
         15 . The method of  claim 1  in which each of the amide branches has one organic group. 
     
     
         16 . (canceled) 
     
     
         17 . The method of  claim 2  in which the compound is a pyromellitamide. 
     
     
         18 - 29 . (canceled) 
     
     
         30 . The method of  claim 17  in which the compound is BTA6 and the hydrocarbon fluid is gasoline. 
     
     
         31 . The method of  claim 17  in which the compound is BTA8 and the hydrocarbon fluid is diesel. 
     
     
         32 . The method of  claim 17  in which the compound is BTA10 or BTA12 and the hydrocarbon fluid is a crude oil. 
     
     
         33 . The method of  claim 17  in which the compound is BTA14, BTA16, or BTA 18 and the hydrocarbon fluid is a heavy oil. 
     
     
         34 . The method of  claim 1  in which the method is applied to reduce the friction of the hydrocarbon fluid in a pipeline, and the compound is added to the hydrocarbon fluid before injecting the hydrocarbon fluid into the pipeline. 
     
     
         35 . The method of  claim 1  in which the method is applied to reduce the friction of the hydrocarbon fluid in a pipeline, and the compound is added to a portion of the hydrocarbon fluid before injecting the portion of the hydrocarbon fluid into the pipeline. 
     
     
         36 . The method of  claim 1  in which the method is applied to reduce the friction of the hydrocarbon fluid in a motor, and the compound is added to the hydrocarbon fluid before injecting the hydrocarbon fluid into the motor. 
     
     
         37 . The method of  claim 1  in which the method is applied to reduce the friction of the hydrocarbon fluid in a motor, and the compound is added to a portion of the hydrocarbon fluid before injecting the portion of the hydrocarbon fluid into the motor. 
     
     
         38 . A method of lowering the viscosity of bitumen or a mixture of bitumen and a diluent, the method comprising adding to the bitumen or mixture a compound comprising an aromatic core of one or more aromatic rings, and two or more amide branches distributed about the aromatic core, each of the two or more amide branches having one or more organic groups. 
     
     
         39 - 45 . (canceled) 
     
     
         46 . The method of  claim 38  in which the aromatic core is benzene. 
     
     
         47 - 50 . (canceled) 
     
     
         51 . The method of  claim 38  in which the aromatic core is naphthalene. 
     
     
         52 . The method of  claim 38  in which each of the amide branches has one organic group. 
     
     
         53 . The method of  claim 38  in which the compound is not a pyromellitamide. 
     
     
         54 . The method of  claim 38  in which the compound is a pyromellitamide. 
     
     
         55 - 67 . (canceled)
