New Phase

1,4-Bis (dimethyl) benzyl octyl ethylene diammonium bromide chloride has been synthesized, characterized and applied as new phase transfer catalyst in the alkaline hydrolysis of PET leading to depolymerisation. The new phase transfer catalyst has been compared with the alkaline hydrolysis of PET using zinc sulfate as catalyst in the depolymerization. It was found that the newly synthesized phase transfer catalyst exhibited excellent conversion than the alkaline hydrolysis of PET using zinc sulfate as catalyst.

Alkaline hydrolysis of substituted benzyl chloride (BzCl) in ionic liquid [bmim]BF4 is investigated. The presence of the [bmim]BF4, increased the solubility of substituted BzCl in aqueous solutions and increased the selectivity toward the formation of benzyl alcohol. The main advantages of the present procedure are shorter time, higher yields, benignancy to environment and no by-products.
