The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

Kinetics of the neutral hydrolysis of 4-nitrophenyl chloroacetate was investigated in water and in the presence of 1 mol % of ethanol, propanol, and -butyl n alcohol without sonication and under ultrasound at 25 kHz. Similarly, the kinetics of the acid-catalysed hydrolysis of -propyl n acetate in ethanol–water binary solutions was investigated without sonication and under ultrasound at 22 kHz. ...

The formation of 1-butyl-3-methylimidazolium-2-carboxylate in the mixture of CO(2) with 1-butyl-3-methylimidazolium acetate under mild conditions (298 K, 0.1 MPa) has been put in evidence in the liquid phase using Raman and infrared spectroscopy complemented by DFT calculations and NMR ((1)H, (13)C, (15)N) spectroscopy.

A specially designed thermal vaporiser was used with a process mass spectrometer designed for gas analysis to monitor the esterification of butan-1-ol and acetic anhydride. The reaction was conducted at two scales: in a 150 mL flask and a 1L jacketed batch reactor, with liquid delivery flow rates to the vaporiser of 0.1 and 1.0 mLmin(-1), respectively. Mass spectrometry measurements were made a...

Liquid-Liquid Equilibrium (LLE) data are measured for the ternary mixtures of water + 1-butanol + butyl acetate and quaternary mixtures of water + 1-butanol + butyl acetate + glycerol at atmospheric pressure at 313.15 K. In addition, isothermal vapor–liquid–liquid equilibrium (VLLE) data are determined experimentally at 333.15 K. The region of heterogeneity is found to increase as the hydrophil...

In the title mol-ecule, C(12)H(15)NO(5), the nitro-phen-oxy portion is approximately planar (r.m.s. deviation = 0.034 Å) and makes an angle of 84.8 (1)° with respect to the -CH(2)-C(=O)-O-C fragment. In the crystal, π-π stacking is observed between nearly parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.6806 (10) Å. Weak inter-molecular C-H⋯O hydrogen bondin...

The rate of hydrolysis of esters in solution is highly dependent on the nature of the alcohols, e.g. hydrolysis of methyl acetate is twice as fast as that of ethyl, n-propyl and n-butyl acetate and six times as fast as that of i8opropyl acetate (Smith & Olsson, 1925). The fact that the different wool esters hydrolyse at approximately the same rate suggests that the rate-controlling step in the ...
