Abstract: The invention relates to a process for optimizing the properties of aqueous polymer solutions used for polymer flooding which comprises treating the polymer solutions under turbulent flow conditions in dynamic fluid dispersing or pumping equipment such that the residence time of the polymer solution in this equipment is less than approximately 20 seconds and the pump energy used is from about 1 to about 15 watts/liter of solution processed. This process permits the optimization of flow properties important in polymer flooding which results in the improved efficiency of the polymer flooding process.

Abstract: Corrosion inhibitor contains: (A) 2-98 wt.% of a condensation product of diethylenetriamine or dipropylene triamine with (un)satd. 6-22C fatty acids in mol. ratio of 2-1:1-2.5, which has been partially converted into corresponding ammonium salts; and (B) 0-70 wt.% organic solvent. The novelty is that the inhibitor further contains (C) 2-98 wt.% of a condensation product, as corrosion inhibitor, of an amine mixt. of: (a) 20-70 wt.pts. N-(2-aminoethyl)ethanolamine; (b) 30-80 wt.pts. polyamines of formula: H2N-(CH2)m-NHn-H (where m = 2 or 3; and n = 3-8); and (c) 0-20 wt.pts. further aliphatic amines, with (un)satd. 6-22C fatty acids in mol. ratio of 2-1:1-2. An alternative corrosion inhibitor is also claimed.

Abstract: Fuels for spark-ignition engines contain minor amts. of copolymers, of mol. wt. 500-20,000, of maleic anhydride (MA) with (i) 2-40C olefins (A) and/or 3-10C cycloolefins (B), or (ii) 1-30C-alkyl vinyl ethers (C) and/or 3-10C-cycloalkyl vinyl ethers (D), or (iii) (C) and/or (D) and (A) and/or (B); in which the carboxyl gps. of the copolymers are wholly or partly reacted with alkali (ne earth) to form the corresp. salts, and the remaining carboxyl gps. are reacted with alcohols and/or amines with up to 50C to form the corresp. esters, amides or ammonium salts. The copolymers pref. contain at least 3 wt. % alkali or alkaline earth, esp. K. The fuel pref. contains 10-2,000 ppm of the alkali (ne earth) metal salts of the copolymers.
