The invention discloses a method for producing CLT acid nitride in a continuous pipelization mode. The method includes the following steps that 1, CLT acid sulphonate and chlorine gas are continuously introduced into a chloridizing pipeline reactor to be subjected to a chlorination reaction; 2, a chlorination reaction solution obtained in the step 1 and nitric acid are continuously introduced into a nitrating pipeline reactor to be subjected to a nitratlon reaction to obtain the CLT acid nitride. In the method, it is unnecessary to purify an intermediate in the reaction process, and the method is easy to operate, high in reaction efficiency and high in target product selectivity.
