Synthesis and Characterization of some copolymers of Aniline, and study its Applications

In this study, several samples of a common polymer (aniline-phenolformaldehyde) we prepared by condensation polymerization method based on aniline, phenol, formaldehyde and in the presence of a catalyst of ammonia solution at different concentrations.

Relationship between the octane number of motor gasoline and its aniline point

Aniline point is an indicator of chemical composition of motor gasoline and diesel fuel and of their aromatic and paraffinic contents in particular. A significant relationship between the research octane number of unleaded motor gasoline and its aniline point was investigated. This relationship was evident in particular in the case of aromatic and naphthenic compounds with higher octane numbers. A correlation equation with a correlation coefficient of 95% was found with an acceptable average error.

Thermal and Catalytic Cracking of Rubber Polystyrene

This research depends on treating different waste polystyrenes like; general purpose polystyrene, foamed polystyrene (styropor), high impact, and rubber modified polystyrene (HIPS) by thermal cracking in order to have liquid products which might be used as additives to gasoline. These products are essentially aromatics and aromatic olefines of a high octane number > ١٠٠, free from sulfer and lead, and they are able to be used as octane boosters. It is possible to redistill these products in order to have styene monomer with a yield of ٤٠ - ٤٣٪, which can be used after that for polymerisation purposes.
