- W2373746472 abstract "N,N'-alkylene bis[N-(sodium ethylenesulfonate) dodecylamides],DTM(12-s-12) or 12-s-12 shortly,are synthesized from alkylenediamine(s),2-bromoethylenesulfonate,and lauryl chloride as starting materials.The synthetic procedure is described.The characteristic IR absorption bands are assigned for 12-4-12 as a presentative of 12-s-12.The cmc values of 12-2-12,12-4-12,and 12-6-12 at 25℃ obtained by using surface tension-concentration relationships are of 4.81×10-4,5.67×10-4,and 6.75×10-4 mN/m,respectively.Geminis 12-s-12 decrease the contact angle on a hydrophilic glass surface(original value 41°),making it more and more water wetting,and on an oleophilic glass surace(120°),making it water wetting;the wettability alternation capability(WAC) of these geminis is more stronger than that of common surfactant TLS and DTAB with 12-2-12 possessing the strongest WAC.The IFT values with a simulation oil of μ=12.89 mPa·s are measured at 60℃ for 12-s-12/AP-P4(2 g/L)/water,or SP,systems and Na2CO3(10 g/L)/12-s-12/AP-P4(2 g/L)/water,or ASP,systems,in which AP-P4 is a hydrophobically associating polymer,and it is shown that the IFT of SP systems decreases to a steady value of magnititude 10-2 mN/m when the 12-s-12 concentration is above its cmc and ASP systems,wider ultralow IFT zones of 10-3 mN/m are observed with a minimum located near the cmc of the 12-s-12;these geminis are arranged in interfacial activity in order: 12-2-1212-4-1212-6-12.Oil saturated sandpacks(0.34 m long,of water phase permeability 1.3—1.4 μm2) are waterflooded for oil recovery until 98% watercut reached and then are treated by 0.3 PV of a polymer(2 g/L AP-P4) an SP or an ASP slug,containing 0.35 g surfactant 12-2-12 per liter,followed by water flood to give an enhancement in oil recovery of 19.75%,31.64% or 37.21%,respectively." @default.
