Other manufacturing techniques include the SH-process invented by Schnurr, the K-process patented by Kndffler, the W-process patented by Wolfram, the E-process patented by Erbele, and the KA-method invented by Knoffler and Apel and also Bachmann. 

The W-process is based on the condensation of potassium amido-sulfonate with formaldehyde, and the nitration of the condensation product as shown in Reaction 7.13 (overleaf). Potassium amidosulfon-ate and formaldehyde are reacted together to produce potassium methyleneamidosulfonate. This product is nitrated to RDX by a mixture of nitric and sulfuric acids.
