Beschreibung

Allgemeine Beschreibung

Ethylbenzene-d₁₀ (d₁₀-ethylbenzene) is a deuterated NMR solvent useful in NMR-based research and analyses. The photodissociation of d₁₀-ethylbenzene at both 193 and 248nm has been studied using vacuum ultraviolet photoionization/multimass ion imaging techniques. The H/D exchange between ethylbenzene-d₁₀ and acidic bridging OH groups in dehydrated zeolites have been investigated in the temperature range of 303 to 393K.

Anwendung

Ethylbenzene-d₁₀ may be used as an internal standard in the headspace solid-phase microextraction gas chromatography-mass spectrometry (HS SPME-GC-MS) analysis of odorous volatile aromatic compounds (OVACs).
