Abstract
ABSTRACTTwo new poly(ionic liquid)s (PILs) were synthesized, characterized, and applied in breaking water-in-oil (W/O) emulsions. For that, tetraethylene glycol (TG) was treated with thionyl chloride, obtaining dialkyl chloride (TC). TC was reacted with diamines 1,5-diaminopentane (AP) and 1,11-diaminoundecane (AU), forming the corresponding polyamines, TC-AP and TC-AU. Following this, TC-AP and TC-AU were quaternized with acetic acid (AA), producing poly(ionic liquid)s (PILs), TCAP-PIL, and TCAU-PIL, respectively. Chemical structures, thermal stability, surface activity, aggregation size, and zeta potential measurements were investigated using several techniques. In addition, their performance in breaking (PB) W/O emulsions in different ratios was investigated. TCAP-PIL and TCAU-PIL exhibited high PB at all ratios, while their performance improved as the crude oil ratio decreased. Moreover, TCAU-PIL showed higher PB than TCAP-PIL, which may be linked to the increased hydrophobicity of TCAU-PIL due to increased methylene units in the diamine chain compared to TCAP-PIL.KEYWORDS: Poly(ionic liquid)sdemulsificationwater-in-crude oil emulsion AcknowledgmentsThe authors acknowledge the financial support through Researchers Supporting Project number (RSPD2023R688), King Saud University, Riyadh, Saudi Arabia.Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Additional informationFundingThe authors acknowledge the financial support through Research Supporting Project number (RSPD2023R688), King Saud University, Riyadh, Saudi Arabia.
期刊介绍:
This international journal deals with fundamental and applied aspects of separation processes related to a number of fields. A wide range of topics are covered in the journal including adsorption, membranes, extraction, distillation, absorption, centrifugation, crystallization, precipitation, reactive separations, hybrid processes, continuous separations, carbon capture, flocculation and magnetic separations. The journal focuses on state of the art preparative separations and theoretical contributions to the field of separation science. Applications include environmental, energy, water, and biotechnology. The journal does not publish analytical separation papers unless they contain new fundamental contributions to the field of separation science.
