High-performance thin-film composite polyetheramide membranes for the dehydration of tetrahydrofuran
In this study, a series of pervaporation membranes is fabricated through interfacial polymerization involving a diamine and trimesoyl chloride (TMC). Three diamines are used: 2-bis(2-aminoethoxy)ethane (BAE); 3,9-bis(3-aminopropyl)-2,4,8,10-tetraoxaspiro[5,5]undecane (BATO); and 1,8-octanediamine (ODA). They differ in chemical structures and functional groups. The functional groups between the two terminal amines in BAE and BATO comprise ether groups, whereas ODA has only alkane groups. BAE or BATO reacts with TMC producing polyetheramide; the product of ODA and TMC is polyamide. Among the diamines, BAE results in a composite membrane with the most compact active layer (hence, the least free volume). This result is attributed to the two ether groups that have strong hydrogen bonding and electrostatic interaction with the amide groups. In addition, the linear orientation of the ether group contributes no steric hindrance between BAE and TMC. The polyetheramide membrane from BAE and TMC exhibits a high permeation flux of 1399 +/- 132 g m(-2) h(-1) and a high concentration of water in the permeate of 99% (feed = 90% aqueous tetrahydrofuran solution at 30 degrees C). Therefore, composite polyetheramide membranes with a suitable chemical structure, fabricated under optimum conditions, deliver high efficiency for separating water from tetrahydrofuran through pervaporation.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 97-99-4. SDS of cas: 97-99-4.
