New products of polycondensation of formaldeliyde with aromatic hydrocarbons.
Experimental author results on the use of technogenic phenols as inhibitors are presented to undesirable polymerization in petrochemical manufactures. The basic ways of increase inhibiting properties of coke-chemical phenols are shown, such as rectification for separation of two-nuclear derivatives or some examples of their chemical modification, allowing to increase the inhibiting You can write a book review and share your experiences.

Report of academia of science of Ukraine, vol 5. pp – (Russian) Google Scholar On heat-treatment of aromatic hydrocarbons, polycondensation reactions occur resulting in formation of mesophase which is the precursor of graphitizable carbon fibers and carbons.
Changes in the molecular structures and molecular arrangements during this process are monitored as electronic transitions in the Vis and near-IR :// Abstract. New process of thermal transformation of organic molecules is elaborated. First fullerene C 60 and at its hydrides are synthesized at polycondensation of molecules of benzene and at temperatures excluding sublimation of carbon.
New closed heteroatomic molecule C 50 N 10 O 4 H 10 is formed during polycondensation of pyridine molecules. Red molecular crystals of this substance are easy Aromatic compounds can also be degraded anaerobically, via reductive pathways, which have been reviewed.

The MDI data given in this report are applicable to both MDI monomer and polymer; differences between the two have been found to be insignificant. A variety of different polyols are used in the production of different specifications of polyurethane and the principal operations are shown schematically in Figure The polymers were synthesized by a two-step polycondensation route with a total of 4 aromatic dianhydrides, 4 aromatic diamines, and 3 diamino-terminated aliphatic oligomers containing either ether or siloxane units.
Pervaporation experiments were conducted at two temperatures with toluene/n-heptane and benzene/n-heptane mixtures as feed Heading No. shall include products similar to those obtained by the distillation of high temperature coal tar but which are obtained by the distillation of low temperature coal tar or other mineral tars, by processing petroleum or by any other process, provided, that the weight of the aromatic constituents exceeds that of the non-aromatic Processes for conversion of lignin to products such as phenolic compounds and biofuels prepared from such phenolic compounds are disclosed and described.

Analysis of the pyrolysis products was provided and the pyrolysis oils were found to contain valuable chemical products while the pyrolysis gases were mainly halogen free, making them suitable to be used as a fuel. Pinto et al. investigated the influence of several catalysts on product distribution from plastic waste pyrolysis.
The waste under For example, shorter-chain hydrocarbons, such as pentadecane (C 15 H 32) and hexadecane (C 16 H 34), were the major products at °C, while longer-chain hydrocarbons, such as tetrapentacontane (C 54 H ) and hexacontane (C 60 H ), were observed along with other hydrocarbons at and °C, respectively.
