为推广聚丙烯酰胺(PAM)在二氧化碳驱提高采收率中的应用,采用动态法测定了不同分子量(500万、700万、1400万、g·mol-1)聚丙烯酰胺在超临界碳中的溶解度温度为 313、323 和 333 K,压力为 9.0 至 18.0 MPa 的二氧化碳 (SCCO2)。 通过比较在SCCO2中测得的溶解度数据的差异,研究了压力、温度和分子量对PAM在SCCO2中溶解度的影响。 PAM 在 SCCO2 中的溶解度数据与五种基于密度的半经验模型(Chrastil、AL、MT、SS 和 Bartle)相关,AL 模型对不同分子量的 PAM 获得了最佳相关结果。 MT模型验证了PAM溶解度的自洽性。 PAM的焓值,

What is the solubility of polyacrylamide in water?

Polyacrylamide is a high molecular weight (eg. 3 to 15 million number-averages MW) and very hydrophilic non-ionic polymer. Its solubility in water is significant. Its solubility in non-aqueous solvents is restricted to those that are very polar, such as glycerol, formamide, and ethylene glycol.

How soluble is ethylene glycol in supercritical carbon dioxide?

Does carbon dioxide dissolve poly (butyl methacrylate)?

Carbon dioxide does dissolve poly (butyl methacrylate) (PBMA) at temperatures above 120 °C and pressures slightly higher than those needed to dissolved poly (butyl acrylate) (PBA), although in this case the Tg for PBMA is only 70 °C higher than that of PBA.

Does carbon dioxide dissolve poly(dimethyl) and poly(phenylmethyl) polymers?

Carbon dioxide at or near room temperature readily dissolves many poly (dimethyl) and poly (phenylmethyl) silicones, perfluoroalkylpolyethers, and chloro- and bromotrifluoroethylene polymers (Hoefling et al., 1991; Krukonis, 1985; McHugh and Krukonis, 1984; Xiang and Kiran, 1995; Yilgor et al., 1984).

How does density affect the solubility of a polymer?

For example, given that the internal energy of the mixture is roughly proportional to density, the solubility of a polymer is expected to improve by increasing the system pressure, by using a denser SCF solvent, or by adding a dense liquid cosolvent to an SCF solvent.
