(2-Hydroxyethyl)ammonium lactates have been prepared by reactions of the corresponding (2-hydroxyethyl) amines with lactic acid and characterized by their 1 H NMR, IR, and mass spectra. They have been quantitatively analyzed by HPLC, and their water contents have been determined by the Karl-Fischer method. The title salts are low-melting solids or viscous liquids, and they belong to the class of polar, hydrophilic ionic liquids. The toxicity and chemical and biological degradation of the synthesized ionic liquids have been evaluated by methods described in European Standards. The measurements showed these ionic liquids to be highly biodegradable and only slightly toxic substances. Condensation reactions of benzaldehyde with ethyl cyanoacetate and with acetophenone have been performed in these materials as solvents. The possibility of simultaneously applying these ionic liquids as both solvents and catalysts for the mentioned reactions has been demonstrated, as well as repeated use of the same ionic liquid for a number of condensation reactions without any purification.

This work includes preparing of some new derivatives of pyrimidine , pyrazole , and isoxazole from the reaction between benzylideneacetophenone (chalcone) (1) and hydrazine derivatives in the presence of sodium acetate and dry acetone to obtain heterocyclic compounds (2-6). Reaction of (2) with different substituted benzaldehydes in absolute ethanol and drops of glacial acetic acid gave Schiff bases derivatives (8- 10) respectively. Schiff bases (8-10) were reacted with sodium azide in THF to give tetrazole derivatives (11-13). Reaction of (2) with sodium nitrate and concentrated hydrochloric acid , then with phenol gave diazo compound (7). The prepared compounds were diagnosed mediated FT.IR,'H- NMR,UV/Vis spectra, melting points were recorded and the purity was checked through TLC technique. The biological effectiveness were measured for some prepared compounds.
