Abstract
Process for obtaining mono-, di- or poly-hydroxy-alkyl-xanthines and their nitric esters consisting essentially of treating a xanthan base in the form of its sodium, potassium or analogous salt with a halide of mono-, di- or poly -hydroxy-alkyl in hot and concentrated aqueous solution, isolating the resulting product in the usual way and, once dry, treat it in cold with nitric acid, which can act interchangeably only or in mixture with concentrated sulfuric acid or other acidic compound to act as a catalyst.
