A simple method for the preparation of dinitronaphthalene from the nitration reaction of 1-nitronaphthalene with NO 2 as nitration reagent under the mild conditions has been successfully developed in this work. The results indicated that Ni(CH 3 COO) 2 ·4H 2 O catalyst shows better catalytic performances, and the conversion of 1-nitronaphthalene is 33.10 % with 34.10, 23.56, 19.30, and 3.56 % of the selectivity to 1,5-DNN, 1,3-DNN, 1,4-DNN, and 1,8-DNN, respectively, under the optimal reaction conditions. This is a mild, environmentally benign, and economical method for the preparation of dinitronaphthalene.

Highly selective preparation of valuable dinitronaphthalene from catalytic nitration of 1-nitronaphthalene with NO2 over HY zeolite

Renjie Deng,Kuiyi You,Fangfang Zhao,Pingle Liu,He'an Luo

In this work, a simple method for the highly selective preparation of valuable dinitronaphthalene from 1-nitronaphthalene employing NO 2 as a nitrating agent has been developed. The results demonstrated that HY zeolite as an eco-friendly and stable catalyst exhibits good catalytic performances. The total selectivity to valuable dinitronaphthalene compounds including 1,5-, 1,4-, and 1,3-dinitronaphthalene can reach 87.6 % in our present nitration reaction. Meanwhile, the physico-chemical properties of catalysts were characterized by XRD, FTIR, TG/DTG, BET, and NH 3 -TPD, and the probable nitration reaction mechanism was also suggested in this paper. The present nitration process seems to be a mild, eco-friendly, and economical route for the preparation of valuable dinitronaphthalene compounds.
