       Some  ionic liquids were investigated for abilities to capture COalone or with added some catalysts at room temperature under atmospheric pressure to increase the capacity of ionic liquids  to capture
carbon dioxide gas  some catalysts were found effective such as :- Hydrated aluminum nitrate/urea ionic liquid  with added CaO  and n NaOH , monoethanolamine and  ammonium chloride were added to

Background:
     Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action,or both, the chronic hyperglycemia of diabetes is associated with longterm damage, dysfunction and failure of various organs, especially the eyes, kidneys, nerves, heart, and blood vessels that impose a tremendous burden on the individual with diabetes and on the health care system.Objective:

1-In this study, some organic compounds contain hetero-atoms were synthesized by several steps as following:
 First; 4-phenylazoaniline [1] and 4-phenyl azophenol [17] were prepared in two steps:  
 The treatment of a primary aromatic amine (aniline) with nitrous acid to form a diazonium salt. Coupling reaction of aromatic diazonium ion with activated aromatic ring (aniline, phenol).
