Economic Ways of Isomerisation of Tert Allylic Alcohol by using Alumina Modified with Consumable Acid.

Abstract

Isomerisation of Geraniol-Nerol to linalool and vice versa has been mentioned in the various literature and patents. However, an important factor is to make it economically more viable that can be scaled up to commercial levels. Many transition metal catalysts are known to convert linalool to geraniol-Nerol and vice versa but the main problem is cost of the catalyst, its recovery and its reusability. The current method ,mentioned in the paper, involves the use of a cheaper  organic acid i.e ascorbic acid coupled with alumina catalyst which is low in cost, quantity required is very less, and also gives good conversion with minimum side products.
