Studies on fatty oil derivatives of Pithcellobrium dulce and Buchanania lanzan: possible industrial application

Abstract

Amide derivative prepared from the fatty oil of Pithcellobrium dulce has been found to disperse calcium and magnesium ions. The property can be used in removing the limitation of fatty acid soaps (usually sodium salt) which are good surface active agents but precipitate in hard water. In the preparation of amide derivative, no solvent has been used, thus a green approach has been attempted. The prepared derivative has been identified by IR, NMR and HPLC. In the second part of the study, preparation of a wood adhesive using natural source – Buchanania lanzan flour, has been tried due to high cost and environmental concerns of petroleum based phenol – formaldehyde and urea – formaldehyde resins. The method is economical and ecofriendly. Pithcellobrium dulce (Leguminosae) 1 is a cultivated tree, distributed in Central Madhya Pradesh. Two saponins from P. salman 2 , a triterpenoid glycoside from P.arboreum and P cubense 3 and chemical composition of P. multiforum 4 have been reported. The linoleic –oleic acid rich oil has been analysed in our Laboratory 5 Soaps precipitate with calcium and magnesium, which are present in hard water. To overcome this difficulty, dispersing agents are used alongwith soap based detergents. For preparation of these dispersing agents large amount of organic solvents are used. 6-8 In the present study, solvent has not been used. Buchanania lanzan (Anacardiaceae) 9 is a middle sized tree, distributed in dry hot forests of Bundelkhand 10. Kernels 11 and bark 12 have been worked out. Fatty oil analysis has been carried in our Laboratory. 13 The flour in presence of phenol and formaldehyde has been evaluated in the present study – to know its performance as a
