Synthesis and Evaluation of Novel Polymeric Phosphate Surfactants for Oil-Based Muds

摘要

(Mono, di) alkyl, aryl phosphate-ethoxylate were prepared from coal-tar-phenol. The synthesized ethoxylates were evaluated as water-in-oil emulsifiers in oil-base mud, one type of the drilling fluids used to drill for oil and gas wells by the rotary method. This study presents a new trend of disposal and reuse of cao-tar phenol, a byproduct that causes environmental problems. The newly prepared compounds were confirmed by FTIR and molecular weight determination. Surface properties of the newly prepared ethoxylates were studied via surface tension, emulsion stability, cloud points, critical micelle concentration, and hydrophile-lipophile balance. Also, rheological properties, filtration, and electrical stability were studied to the oil-base mud formulated with the newly prepared emulsifiers compared to the reference sample (commercial emulsifier).View full textDownload full textKeywordsCoal-tar phenol, drilling fluids, oil-base mudRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01932690903224649
