Rheological and infrared data for hydrated tetramethylammonium chloride-citric acid deep eutectic solvents

<p dir="ltr">Steady shear and small-amplitude oscillatory shear measurements, and attenuated total reflectance infrared spectra, of tetramethylammonium chloride and citric acid (TMAC:CA) deep eutectic solvents at a 1:1 molar ratio with 10, 20 and 30 wt.% added water, together with screening flow curves of the choline chloride formulations from which that composition was selected. The rheometry was carried out on an Anton Paar MCR 302, on a 25 mm parallel plate and on a 50 mm one degree cone and plate, between 5 and 45 degrees C. The cone flow curves include the first normal-stress difference, recorded in both directions of the shear rate ramp on a single loading.

The infrared spectra were collected on an Agilent Cary 630 with a diamond ATR accessory. The files are the instrument exports as written by the instrument software, converted to UTF-8 and renamed so that the sample, the geometry and the test are readable from the file name.
