1. SEMINAR ON ADVANCE ORGANIC CHEMISTRY-I (MPC 102T) TOPIC: Aluminium Isopropoxide Prepared By: Abu Saleh Nizam Uddin Siddik

2. INTRODUCTION It is used as a catalyst and an intermediate in different reactions. This belongs to aluminium alkoxide group. Widely used as a reducing agent for aldehydes and ketones. It is an inexpensive and easy to handle among the other alkoxides.

3. STRUCTURE OF ALUMINIUM ISOPROPOXIDE FIGURE 01: ALUMINIUM ISOPROPOXIDE

4. PHYSICAL PROPERTIES It is a white solid and the molecular formula of aluminium isopropoxide is Al(O- i -Pr) 3 . It is more soluble in benzene and less soluble in alcohol. Boiling Point: 140 o C Melting Point: 128 o C-133 o C It is highly flammable and irritant. It is moisture sensitive so it must be stored in air tight container.

5. SYNONYMS Tri isopropoxyaluminium Aluminium isopropoxylate 2-proponol alumium salt

6. PREPARATION It is prepared by reaction between isopropyl alcohol and aluminium salt.

7. APPLICATION It is used in Meerwein-Pandroff Verely reaction. Carbonyl compounds are reduced to the respective alcohol in the presence of aluminium isopropoxide. The acetone, so formed is removed by slow distillation and hence the reaction proceeds only in the desired direction.

8. APPLICATION It is used in Oppenauer oxidation. -alcohol to ketone in the presence of aluminium isopropoxide

9. APPLICATION Hydrolysis of Oximes Oximes can be converted into parent carbonyl compound in presence of aluminium isopropoxide followed by acid hydrolysis.

10. APPLICATION Conversion of Anthraquinone to Anthracene .
