In this work, the novel deep eutectic solvents (DESs) based on 3-amino-1-propanol (AP) as hydrogen bond donor (HBD) and tetrabutylammonium bromide (TBAB) or tetrabutylammonium chloride (TBAC) or tetraethylammonium chloride (TEAC) as hydrogen bond acceptors (HBAs) were synthesized with different molar ratios of 1: 4, 1: 6 and 1: 8 salt to AP. Fourier Transform IR Spectroscopy measurements were performed to provide an evidence of any chem. structure changes. Phys. properties of the prepared DESs including densities, viscosities, refractive indexes and sound velocities were measured within the temperature range of 293.15-333.15 K at the pressure of 0.1 MPa. They were analyzed in terms of estimating the effect of HBA to HBD molar ratio, anion and length of alkyl chain in a salt, and their temperature dependences were fitted by empirical equations. Thermal expansion coefficients and activation energies for viscous flow were obtained accordingly. Moreover, exptl. values of d. and refractive index were compared with predicted ones. For prediction of d., Rackett equation modified by Spencer and Danner and the mass connectivity index-based method were used, while refractive index was estimated by the at. contribution method.3-Aminopropan-1-ol(cas: 156-87-6Electric Literature of C3H9NO) was used in this study.
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Primary amines having a tertiary alkyl group (R3CNH2) are difficult to prepare with most methods but are made industrially by the Ritter reaction. In this method a tertiary alcohol reacts with hydrogen cyanide (HCN) in the presence of a concentrated strong acid; a formamide, RNH―CHO, is formed first, which then undergoes hydrolysis.Electric Literature of C3H9NO
