Description

General description

1,2-Bis(triethoxysilyl)ethane (BTESE) is a silsesquioxane precursor which is mainly used in the preparation of mesoporous organic materials. It can tune silica networks which makes them useful in applications related to molecular separation.

1,2-bis(triethoxysilyl)ethane is a non-functional silane and a double trialkoxysilyl precursor.

Application

1,2-bis(triethoxysilyl)ethane may be used to prepare mesoporous organosilica materials. Amine functionalization of mesoporous silica can be undertaken by this silane. It may form inorganic hybrid membranes with poly(vinyl alcohol). Effect of this crosslinking silane on the bonding of bis-GMA (bis-phenol-A-diglycidyldimethacrylate) resin to silicatized titanium was investigated.

BTESE can be used as an anti-corrosive coating on aluminium magnesium alloy (Al93Mg7) for potential application in nuclear and food processing industries. BTESE membranes are chlorine resistant and can be thermally stable at 100°C. They which can be used in gas permeation (GS) and reverse osmosis (RO) applications. It may also form a mesoporous hybrid monolith with tetramethoxysilane by a sol-gel condensation method with enhanced chemical stability for peptide separation.

Packaging

25 mL in poly bottle
