    • The present invention discloses a process for producing polyalkylated arylalkyl sulfonic acids by reacting arylalkyl sulfonic acids with olefins. The polyalkylated arylalkyl sulfonic acids may be further neutralized with alkalis or amines to form the corresponding sulfonated salts. The present invention also makes possible manufacture of polyalkylated arylalkyl sulfonic acids as first intent products using an inexpensive and simple reaction. The structure of the polyalkylated arylalkyl sulfonic acids produced using the process described in the present invention is shown below: Where R1, R2 and R3 are each separately and independently H, alkyl (branched or linear C1 to C30), (—CH2CH2O)a, (—CH(CH3)CH2O)b, or (—CH2CH2O)c(—CH2(CH3)CH2O)d, m+n=8 to 28 R4=CH2CH3, CH2CH3Y or Y(CH2)pCH(CH2)qY p+q=0 to 27 a=1 to 30 b=1 to 30 c+d=2 to 30 Y=CH3, COOH, CH2OH, CH2(—CH2CH2O)a, CH2(—CH(CH3)CH2O)b, CH2(—CH2CH2O)c(—CH2(CH3)CH2O)d, aromatic, or substituted aromatic.

    • Sulfonated betaines amine oxides, and sultaines are made by the reaction of the corresponding unsaturated betaines or sultaines. These are formulated into injection fluids suitable for the recovery of residual oil from subterranean reservoirs. The sulfonated betaines, amine oxides, and sultaines exhibit lower adsorption onto reservoir rock compared to their corresponding unsulfonated betaines, amine oxides, and sultaines. They can be used in applications where their respective amphoteric surfactants are currently used such as personal care, mining, improved oil recovery (IOR), oil field drilling, fracturing, acidizing, foaming, oil field stimulation, and agricultural formulations.
