Abstract:
Xylene is one of the materials that could be used for synthesis of different carbon nanoparticles including perfect carbon spheres with diameters of 1 to 8 microm and ellipsoids. Its changes in the course of the pyrolytic process in a hermetically sealed stainless steal container have been examined by stopping the process at different stage of temperature treatment from 100 degrees C to 600 degrees C. The prepared material is in a liquid phase up to 400 degrees C and its relative weight and optical transmittance changes have been measured. The origins of these changes are traced to solid micro and nanoparticles and their morphology, which was studied by Scanning (SEM) and Transmission Electron Microscopy (TEM), X-ray diffraction (XRD), Electron Probe X-ray Micro Analysis and Energy Dispersive X-ray Spectrometry (EDS), and Fourier Transform Infrared Spectroscopy (FTIR).

Oxidation reactions are fundamental in aromatic carbon-containing systems. An example is the hydroxylation of phenobarbital, a process that transforms it into...
Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
