General description

Tetraethylammonium fluoride hydrate is a quaternary ammonium salt, is commonly used as a deprotection reagent in organic synthesis for the deprotection of silyl ether functional groups. It also acts as a mild and selective fluoride ion donor in fluorination reactions.

Application

Tetraethylammonium fluoride hydrate can be used as a homogeneous catalyst in the selective methanolytic depolymerization of poly(lactic acid) PLA.

Many synthesis parameters can influence zeolite crystallization, which include the molar ratio of reagents, water content, temperature, the selection of extraframework cations (organic or inorganic template) and so on. In this paper, two new materials, BUCT-1 with cuboid morphology and

A micro-spectroscopic method has been developed to probe the accessibility of zeolite crystals using a series of fluorescent 4-(4-diethylaminostyryl)-1-methylpyridinium iodide (DAMPI) probes of increasing molecular size. Staining large zeolite crystals with MFI (ZSM-5) topology and subsequent mapping of the resulting
