non-hydrolysable aliphatic compounds that resist aqueous dichromate oxidation (Knicker et al.
The pyrolysis products were grouped according to their chemical structure into the following classes: (i) aliphatic compounds (homologous scries of n-alkanes and n-alkenes, and branched alkencs), (ii) lignin-derived methoxyphenols, (iii) phenols, (iv) monocyclic aromatic compounds (MAHs), (v) polycyclic aromatic hydrocarbons (PAHs), (vi) N-containing compounds, (vii) carbohydrate-derived pyrolysis products, and (viii) unidentified compounds.
Infrared microscopy can be used to identify hydrophobic aliphatic compounds
in the coating on a single sand grain.
The company's overall R&D program emphasizes treatment of groundwater contaminated with chlorinated aliphatic compounds
, particularly TCE.
It is not possible (according to the available knowledge) to eliminate the formation of PAH in the obtained oil without elimination or decreasing the aromatization processes via secondary reactions through either a Diels-Alder type reaction or selective cracking of aliphatic compounds resulting in selective concentration of aromatic compounds.
The formation of aromatics via secondary reactions during pyrolysis has been attributed to Diels-Alder type reactions or to gas-phase cracking of aliphatic compounds resulting in selective concentration of aromatic compounds.
Gas Phase Selective Oxidation of Aliphatic Compounds
Also offers Bromoklor bromo-chlorinated aliphatic compounds
effective as high-halogen plasticizers.
Also available are a series of bromo-chlorinated, aliphatic compounds
called Bromoklor, which are effective as high-halogen plasticizers.
