Diethylene glycol dimethyl ether (diglyme) is interesting as a representative of ethers with several oxygen bridges in the molecule and as a model alternative fuel. A comparative study of the diglyme radiolysis at room temperature and at the boiling point was carried out. Boiling facilitates the...

Dimeric copper(II) complexes [CuII2L2] of a series of amine-bis(phenolate) ligands (H2L) bearing different non- or weakly coordinating side-arms such as ethyl (H2LEt), n-butyl (H2LBu), thiomethyl (H2LSMe) and hydroxyl (H2LOH) were synthesized. They were characterized by X-ray crystallography, UV...

2-Methoxyethanol and bis(2-methoxyethyl)ether were subjected to the following assays for genetic toxicity: Ames' test, unscheduled DNA synthesis (UDS) assay in human embryo fibroblasts, sex-linked recessive lethal (SLRL) test in Drosophila, dominant lethal test in male rats, bone marrow met...

Volatility is a critical criterion for amine selection for CO2 capture from low pressure gas streams. The Henry's law constant (Ham) in water of 24 novel amines, including 18 tertiary amines, 3 hindered amines, 2 ether amines, and 1 pyridine derivative was measured at 40 °C using a hot gas...

A mild, efficient, and practical method for the one-step synthesis of benzonitriles from phenylacetic acids using bis(2-methoxyethyl)aminosulfur trifluoride is described. The reaction was easily extended to the synthesis of the corresponding phenylacetonitriles by inclusion of triethylphosphine.

A mild, efficient, and practical method for the one-step synthesis of acyl azides from carboxylic acids using bis(2-methoxyethyl)aminosulfur trifluoride is described. The reaction was easily extended to the synthesis of the corresponding nitriles by the inclusion of phosphorous reagents. The met...

The bis(2-methoxyethyl)dithiocarbamate complexes [M{S2CN(CH2CH2OMe)2}2] (M = Ni, Cu, Zn, Pd) are readily prepared and the three lighter complexes have been crystallographically characterised. Disproportionation of [Cu{S2CN(CH2CH2OMe)2}2] upon addition of Cu(ClO4)2 · 6H2O affords the copper(III)...

The phase separation behavior and solvation of poly(N,N-bis(2-methoxyethyl)acrylamide) (PbMoEA) in water and alcohol/water mixtures were investigated by infrared (IR) spectroscopy. A critical change in IR spectrum informs that PbMoEA undergoes the phase separation at around 54 °C in water. The ...

Neutral tris(trimethylsilylmethyl) complexes [Ln(CH2SiMe3)3(L)] (Ln = Sc (1), Lu (2)) and cationic bis(trimethylsilylmethyl) complexes [Ln(CH2SiMe3)2(L)(THF)]+[BPh4]−, (Ln = Sc (3), Lu (4)) that contain bis(2-methoxyethyl)(trimethylsilyl)amine (L = Me3SiN(CH2CH2OMe)2) as a neutral, tridentate li...

A method for the determination of isocyanates as di-n-butyl amine (DBA) derivatives using tandem mass spectrometry (MS/MS) and electrospray ionisation (ESI) is presented. Multiple-reaction monitoring (MRM) of the protonated molecular ions and corresponding deuterium-labelled d9-DBA derivatives r...

The standard (po=0.1 MPa) molar enthalpies of formation ΔfHmoat the temperature 298.15 K were determined from the standard molar enthalpies of combustion measured by static-bomb calorimetry for the liquids: di-n-propylamine, diisopropylamine, diisobutylamine, and di-sec-butylamine. The standard...

The excess molar volume VE, the viscosity deviation Δη and the excess Gibbs energy of activation ΔG∗E of viscous flow have been investigated from density and viscosity measurements of 15 mixtures of ethanol, propanol, butanol, pentanol, heptanol, octanol and decanol with di-n-propylamine, and...

Excess molar enthalpies HmE have been measured at atmospheric pressure and 298.15 K for (ethyl acetate + n-butylmethylamine or di-n-propylamine or di-n-butylamine) and for (ethyl propionate + n-butylmethylamine or di-n-propylamine or di-n-butylamine). All the mixtures have HmE > 0. For the ester...

This article reports experimental density (ρ) and speed of sound (u) of binary mixtures containing di-n-butyl amine with 1-propanol, 1-butanol, 1-pentanol, 2-propanol over entire composition range at temperature ranging from 293.15 K to 313.15 K and at atmospheric pressure. Excess molar volume ...

The hydroaminomethylation of eugenol with di-n-butylamine was performed employing a bis[(1,5-ciclooctadiene)(μ-methoxy)rhodium(I)] as pre-catalyst. In the absence of phosphines, the catalyst was efficient in the process, but the regioselectivity for amines was poor. For phosphine-promoted catal...

The excess molar volume VmE, viscosity deviation Δη, and excess Gibbs energy of activation ΔG⁎E of viscous flow have been investigated from the density ρ and viscosity η measurements of binary mixtures of methanol with n-butylamine and di-n-butylamine over the entire range of mole fractions...

The rate of Transcutol® (TC)-water interchange, was studied using whole and stripped hairless rat skin in a modified vertical Franz diffusion cell. The presence of stratum corneum limited the passage of the two solvents, but after stripping of the skin, the rate of TC transfer increased and the ...

The binary vapor–liquid equilibrium data of CO2 in diethylene glycol (monomethyl, monoethyl, monobutyl, dimethyl, diethyl, dibutyl) ether were determined from 288.15 to 318.15 K at pressure up to 6 MPa based on the constant-volume method. It was found by contrast that the ether group in solvent...

Temperature dependent solubility data of tadalafil (TDL) in diethylene glycol monoethyl ether (Transcutol) + water co-solvent mixtures are not available in literature. Therefore, the aim of present study was to determine the temperature dependent solubility data of crystalline TDL in mono-solven...

Transcutol® (Diethylene glycol monoethyl ether, DEGEE), CAS # 111-90-0, is commonly used as a vehicle in the formulation or manufacturing process of pharmaceuticals, cosmetics, and food additives. This paper presents unpublished nonclinical safety data using a form of DEGEE which includes a sign...
