Case Study

1,2-Bis(Triethoxysilyl)Ethylene for the Synthesis of Bifunctional Hybrid Mesoporous Organoaluminosilicate

Xia, Yongde, et al. Journal of the American Chemical Society 127.2 (2005): 790-798.

Researchers developed well-ordered mesoporous organoaluminosilicate materials with ethylene content that exhibit both molecular periodicity in their pore walls and enhanced hydrothermal stability. The synthesis required distilled 1,2-bis(triethoxysilyl)ethylene which served as organosilica precursor along with aluminum isopropoxide as aluminum source and cetyltrimethylammonium bromide to function as the template. These prepared materials demonstrate a structured organization while presenting an extensive surface area exceeding 1300 m2/g and pore volume that surpasses 1.10 cm3/g.
Synthesis Procedure
The experiment started by dissolving 4.37 grams of cetyltrimethylammonium bromide (CTAB) in 64.87 grams of distilled water through stirring before adding 0.96 grams of NaOH to reach the required pH level. Next, 3.52 g of 1,2-bis(triethoxysilyl)ethylene was incorporated into the solution, along with a specified amount of aluminum isopropoxide, creating a gel mixture with a molar ratio of 1 BTEE: 1.2 CTAB: x Al: 2.4 NaOH: 360 H2O. The gel stayed mixed for 20 hours at room temperature before it went into the autoclave for aging at 100 °C for 24 hours. Once cooled, the solid product was filtered and thoroughly washed with distilled water. After air-drying, the synthesized material was refluxed in an ethanol solution containing 4 wt % HCl for 2 hours to eliminate the CTAB surfactant, with this solvent extraction process repeated three times to ensure complete removal of the surfactant.

Organic Silicon Membranes Prepared from Precursors Like 1,2-Bis(Triethoxysilyl)Ethylene for Pervaporation Dehydration

Cheng, Linglin, et al. Separation and Purification Technology 344 (2024): 127105.

The petroleum industry commonly encounters mixtures of ethanol (EtOH), isopropanol (IPA), and n-butanol (n-BuOH) with water throughout both production and recovery processes. The pervaporation technique has become an attractive solution for separating azeotropic mixtures because it functions efficiently without being limited by vapor-liquid equilibrium dynamics.
The study used 1,2-bis(triethoxysilyl)ethane (BTESE), 1,2-bis(triethoxysilyl)ethylene (BTESEthy), and 1,2-bis(triethoxysilyl)acetylene (BTESA) as organosilica precursors to create organosilica membranes through the sol-gel method. These membranes were used in the pervaporation dehydration process. Then research examined how the unsaturation level of the bridged group, feed composition, and alcohol carbon chain length affect membrane dehydration performance.
The membranes showed better separation results with n-butanol/water mixtures than with other alcohol/water systems tested. The BTESE membrane showed a high separation factor but was linked to a lower permeation flux. The BTESA membrane exhibited an increased permeation flux while showing a decreased separation factor. During the analysis of gas permeation and pervaporation processes, it was found that organosilica membranes had molecular sieving as their main separation mechanism.
