This unusual process known as the W-method was discovered in Germany by Wolfram and involves the condensation of the potassium salt of sulfamic acid with formaldehyde to form the heterocycle (238) followed by treatment with nitric acid. The extreme sensitivity of (238) to hydrolysis means that nitrolysis has to be conducted under anhydrous conditions using sulfur trioxide or phosphorous pentoxide " dissolved in fuming nitric acid. The yield of RDX from the W-method is 80-90 %. [Pg.246]
