An organic solvent-free microwave-assisted extraction of some priority pollutants of phenols in lake sediments.

Methodologies for the extraction of phenolic compounds from environmental samples: new approaches.

Phenolic derivatives are among the most important contaminants present in the environment. These compounds are used in several industrial processes to manufacture chemicals such as pesticides, explosives, drugs and dyes. They also are used in the bleaching process of paper manufacturing. Apart from these sources, phenolic compounds have substantial applications in agriculture as herbicides, ins...

Microwave-assisted Synthesis of Nـ alkyl 2ـ ketomethyl quinoline Derivatives Under Solvent-free Conditions

A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the  Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.

Chemical Composition and Antibacterial Activity of the Essential Oil of Lavandula angustifolia Isolated by Solvent Free Microwave Assisted Extraction and Hydrodistillation

ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...

Microwave-assisted preparation of Nـ alkyl 2ـ ketomethyl quinolines on Solvent-free Conditions

Comparison of Hydrodistillation, Microwave Hydrodistillation and Solvent Free Microwave Methods in Analysis of the Essential Oils from Aerial Parts of Haplophyllum Robustum Bge. by GC/MS Method

The genus Haplophyllum, which belongs to the Rutaceae family, includes 18 species in Iran. In this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of Haplophyllum robustum Bge. were extracted by three different isolation techniques, conventional hydrodistillation (HD), microwave-assisted hydrodistillati...
