Sym-triazines have been documented for their antitumor, antimicrobial and anti-cancer actions. The present work aims to derive a variety of 1,3,5-triaryl-1,3,5-hexahydrotriazine using ultrasound assisted reactions from the reactions of aryl amines with aqueous formaldehyde. Furthermore, a special study on the different solvents and revealed that mixture of water and ethanol was found to be the ...

It is demonstrated that oxidative debris can be separated and largely removed during the surfactant assisted phase transfer of graphene oxide from a water/ethanol mixture to dichlorobenzene. The new procedure described provides a facile method to obtain monolayer dispersed graphene sheets in a nonpolar solvent via solvothermal reduction of graphene oxide accompanied by an effective purification...

1-Phenyl-2-benzoyl-8-azacycl(2.2.2)azine, VII.-Heating 450 mg of VI in a sublimation tube at 2400 caused rapid evolution of gas. The residue was taken up in a 2: 1 mixture of benzene-Skelly Solve B and chromatographed over alumina (Woelm, activity 3). The solid obtained from the first eluate fraction was recrystallized from an ether-Skelly Solve B mixture to give 312 mg of orange crystals, mp 1...

In an ethanol/water mixture, the nitroxyl radical TEMPO abstracts a hydrogen atom from a phenolic OH group of the amphiphilic para-hexanoylcalix[4]arene, and the hydroxylamine TEMPOH formed yields a stable inclusion complex with another molecule of the calixarene.

This study concerns a new antiretroviral drug named CRS 74, which has a limited bioavailability because of its low aqueous solubility and dissolution rate. To improve these properties, CRS 74 can be recrystallized by using Liquid Anti-Solvent (LAS) crystallization. Ethanol is chosen as the solvent under study for the molecule and water as the anti-solvent. Since solubility data is limited, it i...

A porous coordination polymer [Cu(3)(btc)(2)] with controllable size and morphology from nanocube to microoctahedron was readily synthesized in an ethanol-water mixture at room temperature by adjusting the concentration of the surfactant and the polymer shows size- and morphology-dependent sorption properties.

The paper focuses on experimental investigation and modelling of the evaporation supported ethanol/water droplets in an air flow. is based effective thermal conductivity/effective diffusivity model, using analytical solutions to transient heat transfer species diffusion equations at each time step. contribution supporting thread included model. Model predictions are shown be compatible with dat...

The aim of this study is to develop an extraction method for the producing of a safe and efficient source of antioxidant compounds from fresh and pre-treated sweet orange (Citrus sinensis cv shahsavari) peel. Three types of solvents (100% ethanol, 100% water and ethanol-water mixtures at the ratios of 35:65 and 65:35, v/v), three duration times (60, 120 and 240 min) were chosen as the parameter...

L-a-dipalmitoylphosphatidylcholine (DPPC) liposomes were prepared using supercritical reverse phase evaporation (scRPE) method. The effects of phospholipid structure, preparation pressure, and amount of ethanol on their physicochemical properties were examined using measurements of trapping efficiency, cloud point measurements, dynamic light scattering, and osmotic water transport studies. The ...

BACKGROUND Paclitaxel (taxol) is a very effective anticancer drug. However, the solution used to enhance the water solubility of paclitaxel, a mixture of polyoxyethylene castor oil (Cremphor EL) and dehydrated ethanol, causes irritation. Our aim is to develop a water-soluble taxol with a high anticancer effect. MATERIALS AND METHODS Taxol derivatives (conjugation with aminated dextran, Dex-TX...
