Alkylbenzene Sulfonate Synthesis

As using surfactant for TRO in Daqing oil field,active composition made in American belongs in anion alkybenzene sulfonates,and is special surfacatant system.Through laboratory research and pilot application, it is verifield that ORS-41 is one of the most effecitive surfactant for TRO.At present,Numbers of surfactant made in China are over 1000,but they are applied in textile x chemical , paper, food, madicine etc.For TRO there are a little surfacatants whose effect are not good.In this paper,content of sulfonates and composition of alkyl are decided through right design ;under control reaction conditions different alkylbenzene sulfonates are synthesized;Polyreaction catalyst is developed .non-straight high carbon olefine are made through C9-C12 Polyreaction technolgy;clear composition alkylkenzene is sulfanated in falling-film reactor by SO),product can be adjusted,recipe of the surfacate can be used for super-low interfacialtension with Daqing oil -10-3-10-4mN/m,and stablity is good too.According to method issued by Daqing Develop and Explore Research institute,EOR is over 20% in natural core .In a word,so for there is not factory which can produce surfacant for TRO in Daqing oil field.So, it is important for sustainable Development in Daqing oil field that surfacant system for TRO is developed.
