Process for the continuous preparation of nitrosyl chloride
First Claim
1. A gas phase process for preparing pure nitrosyl chloride which consists essentially of continuously introducing hydrogen chloride and 0.4 to 1 times its molar amount of nitrogen dioxide at the bottom of a reactor, continuously taking off nitrosyl chloride from the top of the reactor, and continuously taking off nitric acid at the bottom of the reactor, the reaction being effected in the presence of little or no water.

Abstract
The reaction of nitrogen dioxide with hydrogen chloride to give nitrosyl chloride and nitric acid can be advantageously carried out in cocurrent in a reactor in such a way that the reactants are introduced at the bottom and the nitrosyl chloride is taken off at the top and the nitric acid is taken off at the bottom of the reactor.
