Reaction Steps

Hydrocodone polistirex was prepared by mixing 4.00 kg of hydrocodone bitartrate with 4.76 kg of ion-exchange resin particles (ABMERLITE IRP69; US Std. Mesh #100-#400) suspended in USP water at about 70° C. The resulting suspension was centrifuged and the product washed with USP water. The wet cake was dried and sieved through a US Std #30 mesh screen. The hydrocodone content of the dried product was equivalent to approximately 56% by weight of hydrocodone bitartrate.
