Research On Technology For Production Of Modified Ammonium Nitrate

Directing at the production unit of Jilin Petrochemical Company, the technology for production of modified ammonium nitrate was carried out. The industrialization testing programs were cofirmed through the laboratory research, at the same time industrialization test was made at the base of the production unit of Jilin Petrochemical Company.The modified ammonium nitrate was made by putting the modification additives into the ammonium nitrate system.Experiment of ammonium nitrate's dehydration performance, fluidity performance, solidification performance show that it has no much effect for modified ammonium nitrate's producting if the modification additives were put into the producting equipments. There is not too much changing for equipments'temperature and volume when the modification additives were put into the producting equipments. By the experiment of modification additives'mixing and solving, and at the base of investigation and study the technological process were recognized. The result of modified ammonium nitrate's XRD and IR experiments at normal temperature, 200℃, 300℃show that modified ammonium nitrate has very high security. The TG and DTA experiment show that the production has too much stability. The modified ammonium nitrate's intermediate control analysis of production were researched, and the rapid determination of SO42-, PO43-, NO3- were cofirmed, at the same time the manufacturer's standards were recognized at the base of investigation and research.It was making the experiment of modified ammonium nitrate's commercial production. The experiments are placidity and success. After the experiment the products'quality and it's physical and chemical character were appraised. The product quality satisfies the request.
