工业丙烯腈中氨测定气相色谱仪
工业丙烯腈中氨测定气相色谱仪详细信息：
在丙烯氨氧化法制备丙烯睛的生产中,氨比为1(理论值)时为理想。如氨比小于此值,则副产物丙烯quan的含量增加,给成品精制带来困难,直接影响丙烯睛成品质量。氨比过大,造成无谓的浪费和生产成本提高。目前生产中,氨比普遍高于理论值。
工业用丙烯腈中氨含量的测定，通常采用 滴定法，此法操作复杂，费时费力，不利于大规模工业生产。
滕州市浩瀚色谱仪器技术服务有限公司，，，，，色谱工程研究所，分析与测试中心，3个科研单位，研发出专用气相色谱仪，配置专用填充柱，气相色谱法，成功测定了丙烯腈中氨的含量，结果满意。

Gas chromatograph for determination of ammonia in industrial acrylonitrile
Detailed information of gas chromatograph for determination of ammonia in industrial acrylonitrile:
In the production of propylene nitrile produced by ammoxidation of propylene, an ammonia ratio of 1 (theoretical value) is ideal. If the ammonia ratio is less than this value, the content of the by-product propylene quan will increase, which will bring difficulties to the refining of the finished product and directly affect the quality of the finished acrylonitrile. The ammonia ratio is too large, causing unnecessary waste and increasing production costs. In current production, the ammonia ratio is generally higher than the theoretical value.
The determination of ammonia content in industrial acrylonitrile usually adopts the titration method, which is complicated to operate, time-consuming and laborious, and is not conducive to large-scale industrial production.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. is advancing with the times, guided by the concept of scientific development, under the leadership of Manager Wang Xiaoying, relying on Xiangying Institute of Analytical Technology, Chromatography Engineering Institute, Analysis and Testing Center, 3 scientific research The unit has developed a special gas chromatograph equipped with a special packed column, and gas chromatography has successfully determined the content of ammonia in acrylonitrile with satisfactory results.
