Small associative molecule thickeners for ethane, propane and butane

摘要: Abstract The abilities of three classes low molecular weight, metal-based, associative compounds to thicken high pressure ethane, propane or butane have been assessed with a close clearance falling ball viscometer. Tributyltin fluoride (TBTF) does not require heating/cooling cycle attain dissolution, and at concentration 1 wt% in yields 70–100-fold viscosity increases 25 °C. Increasing temperature substantially reduces TBTF’s thickening ability. Although hydroxyaluminum di-2-ethylhexanoate (HAD2EH) is insoluble it dissolve liquid after mixing ∼100 °C cooling temperatures as 40 °C. HAD2EH induces small propane, but very effective thickener. causes relatively decrease HAD2EH’s performance. Combining phosphate ester crosslinker translucent that are significantly less than those attained TBTF HAD2EH.
