Nitrophenylsulfonyguaniden en hun splitsing door alkaliën

For preparing sulphaguanidine the reaction of p-nitrobenzenesulphochloride with guanidine in alcaline medium was examined. The controversy 1) which has arisen on the subject of this reaction has been proved to rest on incomplete examination. The chief product in feeble alcaline solution is p-nitrobenzenesulphonyl-guanidine. Being insoluble in alcali, it may be respresented by the formula: ... Zie: Summary
