Abstract: Quaternary oxalkylated polycondensates are described; these are prepared by esterifying, with polycondensation, an oxalkylated primary fatty amine with a diol and with a dicarboxylic acid, and oxalkylating the resulting reaction product in the presence of a carboxylic acid. These polycondensates are used as demulsifiers for breaking crude oil emulsion and as corrosion inhibitors in plants for the recovery and treatment of natural gas and crude oil.

Abstract: Quaternary ammonium compounds of the formula in which R1 denotes an alkyl or alkenyl radical with 12 to 22 carbon atoms; R2 and R3 are identical or different and denote an alkyl radical with 1 to 4 carbon atoms; x denotes an integral or non-integral number from 1 to 3; and A(-) denotes an alkyl- or alkenyl-sulfonate anion, an alkyl or alkenyl-carbonate anion or a benzoate, naphthoate or phenylsulfonate anion, the tosylate ion being excluded, a process for their preparation and their use as drag reducing agents in liquids with turbulent flow.

Abstract: 23221-4469 This invention relates to a process for the preparation of a quaternary ester amine by reacting a glyceride with an alkanolamine, which comprises reacting a glyceride with an alkanolamine of the formula I below (R)3-x-N-¢(CH2CHR10)n-H!x in which R is an alkyl group having 1 to 4 carbon atoms, x is 1, 2 or 3, n is an integer from 1 to 8, and R1 is H or CH3, it also being possible for the (CH2CHR10)n group to contain ethylene oxide and propylene oxide units, and quaternizing the reaction product obtained. These quaternary ester amines show strong surfactant action and can be employed in a wide variety of areas.
