On December 18, experts from China Polyurethane Industry Association organized an appraisal of scientific and technological achievements in Zibo Zhengda Polyurethane Co.
, Ltd.
's project of "Key Technology for Synthesis of Amino-Terminated Polyether (Polyetheramine) by Hydrogen Catalytic Amination"
.
The "Key Technology for Synthesis of Amino-Terminated Polyether (Polyetheramine) by Hydrogen Catalytic Amination" project developed by CP Polyurethane uses polyether polyol, liquid ammonia and hydrogen as raw materials, and uses hydrogen-catalyzed amination to synthesize amino-terminated polyether (polyetheramine) key technology, producing high-quality amino-terminated polyether (polyetheramine), and developing new catalysts and paddle equipment, the catalyst has a long service life and stable performance; at the same time, the reaction temperature and pressure are reduced, and side reactions are less.
, the synthesis conversion rate is high

The "Key Technology for Synthesis of Amino-Terminated Polyether (Polyetheramine) by Hydrogen Catalytic Amination" project developed by CP Polyurethane uses polyether polyol, liquid ammonia and hydrogen as raw materials, and uses hydrogen-catalyzed amination to synthesize amino-terminated polyether (polyetheramine) key technology, producing high-quality amino-terminated polyether (polyetheramine), and developing new catalysts and paddle equipment, the catalyst has a long service life and stable performance; at the same time, the reaction temperature and pressure are reduced, and side reactions are less.
It is understood that CP Polyurethane has developed the synthesis technology of amino-terminated polyethers (polyetheramines) with different molecular weights by the hydrogen catalytic amination method, and has realized industrialization, filling the domestic gap and breaking the foreign monopoly.
The relevant person in charge of CP Polyurethane said that the large-scale application of amino-terminated polyethers in the industrial field began in the 1990s and developed rapidly.
CP Polyurethane is the benchmark enterprise of Shandong gazelle, the "hidden champion" of small and medium-sized enterprises in Shandong Province, and the single champion of manufacturing in Shandong Province.
Previously, more than 95% of domestic amino-terminated polyethers need to be imported from abroad.
Since the production of amino-terminated polyethers is monopolized by a few multinational companies, the source and price of amino-terminated polyethers in China have become the bottleneck restricting the development of polyurethane elastomer technology.
To a certain extent, it affects the popularization and application of reaction injection molding and spray polyurea elastomer technology in China
