It is found that the ferric ions, as a catalyst, have a weak effect on the oxidation of luminol "triaminophtal hydrazid" by (DPCA) and through chemiluminescence reaction. For increasing the catalytic activity of ferric ions we used organic and nonorganic compounds. The best compound was o – phenathroline. It forms two different complexes with ferric (A) and ferrous (B) ions (A, B). The formation of hydrolyzed mixture of the complexes (Ph-Fe3+) depends on the pH. We found that (Ph-Fe3+) complex was very effective in chime-luminescence process above mentioned.

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 b e 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.
In this research, we have used eco-friendly method to prepare four derivatives of 1,2,4-triazole Esters by using the following general nucleophilic substitution reaction.
This research includes the manufacture of the following compounds: Synthesis of three compounds 1- Chlorine esters. 2- Synthesis of ester derivatives of Tiwalbola. 3- Synthesizing a derivative of Tiwalbola, which is Ethylene Tiwalbola. 4- Synthesis of ester derivatives of Ethylene Tiwalpola
The corrosion inhibition of transmision steel in 1M HCl solution in the presence of Succinic acid at temperature (20,30,40,50,60)°C at concentration between (10-6- 10-4) M for two hours were studied using weight loss method.
Some kinetic parameters have been determined in this work for thermal and catalytic cracking of the mixed of polyethylene and polypropylene using batch method. The cracking reaction was carried out at different temperature 470,490 and 510oC under atmospheric pressure. The mass of products (liquid and gas fractions) were determined and used to plot the curves of the thermal and catalytic decomposition. We used two types of catalysts: Syrian natural Zeolite and the same after loading with sulfate ions using impregnation method. The thermal cracking has a long time and has firs-pseud order reaction. While in the case of catalytic process we note that the reaction finished in the short time and the process is the Zero-pseud order reaction. The rate of the cracking increased very much, the rate constant was k1=0.0032.min-1 in the thermal cracking at 4700C and ko=0.111.min-1 in the case of catalytic cracking in presence of Z catalyst and ko= 0.206 min-1 in presence of 15-SO4 2-/Z as catalytic at the same temperature. In the other hand activation energy was 208.7 kj/mol in the thermal process and decreased to 116.6 kj/mol at Z catalytic presence and to 87.3 kj/mol at 15-SO4 2-/Z catalytic presence.
