Case Study

Deuterated Ethyl Acetate as A Low-Cost Solvent for In-Situ Neutron Diffraction Measurement of Lithium-Ion Batteries

Petibon, R., et al. Electrochimica Acta, 2015, 174, 417-423.

The research showed how deuterated ethyl acetate (d8-EA) serves as an economical solvent for high-concentration electrolytes to perform in situ neutron diffraction analysis on lithium-ion battery electrodes.
Li[Ni0.4Mn0.4Co0.2]O2/graphite (NMC(442)/graphite) pouch cells, containing electrolytes with a 1:0.1:2 molar ratio of lithium bis(fluorosulfonyl)imide (LiFSI), LiPF6, and either ethyl acetate (EA) or deuterated EA (d8-EA), were cycled between 2.8 V and 4.7 V at 40 °C for 250 hours. The cells showed stable performance without notable capacity fade, increased polarization, or gas generation.
Deuterated EA-based electrolytes offer an attractive option for in situ neutron diffraction due to their affordability and reliable electrochemical performance. Neutron powder diffraction of NMC(442) soaked in LiFSI:LiPF6:d8-EA produced a signal-to-noise ratio comparable to that of samples using traditional deuterated carbonate electrolytes. With d8-EA costing approximately half as much as conventional deuterated carbonate mixtures, and enabling strong capacity retention at high voltages, this electrolyte blend is highly suitable for in situ studies of lithium-ion battery cathodes under high-potential conditions.

Ethyl Acetate-d8 for the Analysis of Volatile Compounds in Grape Juice and Wine

Slegers, A., P. Angers, et al. J. Food Chem. Nanotechnol, 2017, 3(1), 8-17.

The research employed GC-MS-SPME to analyze volatile compounds in five interspecific hybrid Vitis (IHV) varieties both in their berry form and in wine. The majority of volatile content in grape juice and wine consists of fatty acid degradation products along with fatty acid ethyl esters, terpenes, C13-norisoprenoids, volatile phenols and other phenyl derivatives.
Volatile Compound Analysis in Juice and Wine
Volatile compounds were extracted using headspace solid-phase microextraction (SPME) and analyzed via gas chromatography coupled with time-of-flight mass spectrometry (GC-TOF-MS). For juice analysis, 5 mL of juice was placed in an SPME vial containing 3 g of NaCl and 50 μL of a deuterated internal standard mix (including ethyl acetate-d8, ethyl butanoate-4,4,4-d3, benzyl-2,3,4,5,6-d5 alcohol, 2-phenyl-d5-ethanol, hexanoic-d11 acid, ethyl octanoate-d15, and hexanol-d13). Wine samples (3 mL) were combined with 3 g of NaCl, 3 mL of distilled water, and 50 μL of the same deuterated standard mixture. Extraction was performed using a polydimethylsiloxane/divinylbenzene/carboxen SPME fiber, followed by a 5-minute desorption in splitless mode at the GC inlet. Separation was achieved on a column, and quantification was carried out using the deuterated standards alongside 11-point calibration curves based on authentic reference compounds.
