Abstract:
1. A process for the preparation of a polyol from 3-(8-pentadecenyl)phenol comprising: (a) oxidizing technical grade Cashew Nut Shell Liquid containing 3-(8-pentadecenyl)phenol as the main component (>95%) with a peracid generated in situ from hydro peroxide and an organic acid in presence of a catalyst, in order to oxidize an unsaturation in 3-(8-pentadecenyl)phenol, the ratio of 3-(8-pentadecenyl)phenol to hydroperoxide employed being 1:2, the ratio of 3-(8-pentadecenyl)phenol to organic acid is 1:1, the ratio of 3-(8-pentadecenyl)phenol to organic acid to hydro peroxide being 1:1:2, and reaction temperature maintained in the range of 0° and 80° C. to produce a hydroxy-formoxy ester; (b) subjecting the hydroxy-formoxy ester to hydrolysis with sodium acetate to produce the polyol; and (c) separating the polyol from the unreacted reactants.
