Usage

General Description

ACETAMIDOPROPYLTRIMETHOXYSILANE is a colorless, clear liquid with a faint amine odor. It is a silane coupling agent that is primarily used as an adhesion promoter in adhesive and sealant formulations. This chemical acts as a surface modifier, promoting adhesion between inorganic materials such as glass, metal, and mineral fillers, and organic polymers. It also functions as a water scavenger and cross-linker in moisture-cured systems, enhancing the durability and performance of the final product. ACETAMIDOPROPYLTRIMETHOXYSILANE is commonly employed in automotive, construction, and electronic applications for its ability to improve the bonding strength and water resistance of various materials.

Preparation and chromatographic evaluation of columns for reversed-phase liquid chromatography

Column selection in reversed-phase liquid chromatography is still not a straightforward process. In this study, we have evaluated and compared the performance of several traditional C18 phases with polar-modified phases and found distinct differences in the chromatographic behavior between two groups, as well as a high degree of variability within each group. The polar-endcapped phases exhibit similar hydrophobic selectivity, higher hydrogen bonding capacities and silanol activity with reference to the conventional C18 columns. The polar-embedded phases displayed a greatly reduced hydrophobic nature and a significantly reduced silanol activity compared to the conventional C18 phases. It appears that ionic and/or dipole interactions play a significant role in the overall retention behavior of the polar-modified phases towards basic and acidic analytes.

PROCESS FOR PRODUCING ORGANOALKOXYSILANES FROM ORGANIC ACIDS OR CYANATES AND HALOALKYLALKOXYSILANES

A process for the preparation of organoalkoxysilanes containing one or more organic functional groups derived from organic acids or hydrogen cyanates, by a continuous or batch process utilizing a solid guanidinium salt as a phase transfer catalyst for the reaction between a liquid phase haloalkylalkoxysilane and a solid phase alkali or alkaline earth metal salt or ammonium salt of an organic acid or a metal cyanate.
