1,4-Bis(Chloromethoxy)Butane for the Preparation of Anion Exchange Membranes

Lu, Wangting, et al. Solid State Ionics, 2013, 245, 8-18.

Through a chloromethylation method and a series of homogeneous quaternization/crosslinking strategies of polymers, 1,4-bis(chloromethoxy)butane (BCMB) was used as the chloromethylation agent to successfully prepare a crosslinked membrane (C-QAPPESK/OH), which is an anion exchange membrane.
The preparation procedure of the C-QAPPESK/OH membrane via chloromethylation
· Typically, 1 g of PPESK is dissolved in 30 mL of ice-cold 98% concentrated H2SO4, to which a specified volume of 1,4-bis(chloromethoxy)butane (BCMB) (≥ 95%) is added. The reaction mixture is then maintained in an ice-water bath for a certain duration. The resulting product is isolated by precipitating the mixture in ice water, followed by extensive washing with deionized water and drying in air at 50 °C. This process yields the chloromethylated polymer (CMPPESK).
· Then, N,N,N',N'-tetramethyl-1,6-hexanediamine (TMHDA) was used as a homogeneous quaternization and crosslinking agent to crosslink and quaternize the chloromethylated phthalic acid polyethersulfoneketone (PPESK) during solvent evaporation to obtain the C-QAPPESK/OH crosslinked membrane.

1,4-Bis(Chloromethoxy)Butane for Chloromethylation of Cross-Linked Polystyrene Microspheres

Gao, Baojiao, et al. International Journal of Chemical Kinetics, 2011, 43(12), 677-686.

Three modified cross-linked polystyrene (CPS) microspheres with exchangeable chlorine atoms were successfully prepared as three-phase catalysts (TPCs), which are suitable for the N-alkylation reaction of phthalimide between oil phase and water phase. The modified CPS microspheres were obtained by chloroacylation with different reagents or chloromethylation with 1,4-bis(chloromethoxy)butane (BCMB) as a reagent.
Preparation procedure of modified CPS microspheres
· The three types of modified CPS microspheres included: (1) two types of chloroacylation reagents-chloroacetyl chloride (CAC) and 4-chlorobutyryl chloride (CBC)-which produced two types of chloroacylated microspheres known as CACPS and CBCPS; (2) using BCMB as a chloromethylation reagent to create chloromethylated CPS microspheres, referred to as CMCPS.
· The typical procedure is demonstrated as follows by taking the preparation of CMCPS microspheres as an example. 2g of CPS microspheres were placed in a reactor with a mechanical stirrer, along with 20 mL of chloroform (CHCl3). The microspheres were soaked and swelled for 12 hours. Next, 1.5 mL of BCMB and 1.2 mL of the Lewis acid catalyst SnCl4 were added, and the chloromethylation reaction was conducted at room temperature while stirring for 4 hours. After the reaction, diluted hydrochloric acid was used to neutralize the Lewis acid catalyst. The prepared microspheres were then collected, washed and vacuum-dried to obtain the CMCPS microspheres.
