Celebrating Tiangang Auxiliary's Project Winning the Ministry of Education 'First Prize for Science and Technology Progress'

 Tiangang Auxiliary celebrates its participation in a project awarded the Ministry of Education's First Prize for Science and Technology Progress

Recently, Beijing Tiangang Auxiliary, a leading domestic producer of light stabilizers, together with Tianjin University, won the 2015 Ministry of Education 'First Prize for Science and Technology Progress' for their project 'Key Technologies and Industrialization of Preparation of Azacyclic Fine-Chemical Intermediates.' This is the highest-level science and technology award at the ministry level. The award recognizes the participating enterprise's long-term focus on R&D and production of such fine-chemical additives, and affirms that the participants' technical level in the R&D and production of these chemicals has reached a domestically leading and internationally advanced level.
Hindered-amine light stabilizers (HALS) are sterically hindered organic amine compounds — essentially fine chemicals built on the key 'azacyclic' intermediate derived from triacetoneamine. The technical level of this 'azacyclic intermediate' directly determines the performance of hindered-amine light stabilizers and is one of the core technologies in HALS production processes.
Tiangang is one of the few domestic producers that synthesize light stabilizers starting from the fundamental monomers. In this award-winning project, Tiangang and Tianjin University leveraged their close industry–academia–research collaboration and the company's own production-process strengths to achieve breakthroughs in a series of key technologies — including 'preparation of azacyclic fine-chemical intermediates' — and successfully industrialized a technology representing internationally advanced levels. The new technology not only raises the conversion rate of HALS intermediates and reduces by-product impurities, but also improves the effectiveness and anti-ageing performance of downstream light-stabilizer products, while being environmentally friendly, safe and stable.
As polymer materials find increasingly wide application across every field of human society, consumption of hindered-amine light stabilizers keeps growing year by year; the economic benefits brought by innovation in, and industrial application of, intermediate-preparation technology will also be shared by numerous downstream polymer-material enterprises in plastics, coatings and related industries.
