以二甘醇单丁醚（DGBE）、石蜡油和离子液体（ILs）为原料，制备了一种新型吸附剂。使用三种离子液体，即[bmim][PF 6]、[bmim][BF 4]和[bmim][Ac]来调节吸收性能。采用不同的石蜡油质量分数和IL质量分数，确定了具有合适物理性质和吸附性能的配方。通过测定吸收剂中丙酮的亨利系数，考察了吸收剂组成对吸收能力的影响。在鼓泡瓶中考察了这些吸收剂的去除性能，以评估亨利系数和物理性质的综合影响。
New absorbents composed of diethylene glycol monobutyl ether (DGBE), paraffin oil, and ionic liquids (ILs) were prepared for the removal of gaseous acetone. Three ILs, namely, [bmim][PF6], [bmim][BF4], and [bmim][Ac], were used to regulate the absorption performance. Different paraffin oil mass fractions and IL mass fractions were applied to determine the right formula with suitable physical properties and absorption performance. The Henry coefficients of acetone in the absorbents were measured to evaluate the influence of absorbent composition on the absorption capacity. The removal performances of these absorbents were investigated in a bubbling bottle to evaluate the combined impact of Henry coefficient and physical properties.
