    2007 MDI production technology development and industrialization of Yantai Wanhua won the 1st Prize of National Progress Awards in Science & Technology

    On January 8, 2008, the project of 200,000 tons/year large-scale MDI production technology development and industrialization of Yantai Wanhua Polyurethane Co., Ltd. (predecessor of Wanhua Chemical Group Co., Ltd.) won the 1st Prize of the National Progress Awards in Scientific & Technologyof 2007. Before that, the 1st Prize of the National Scientific & Technological Progress Prize in chemical industry had not been awarded for five years. This project successfully developed a series of advanced processes and technologies, such as, a multistage continuous condensation reaction technology development, receiving almost 20 invention patent licenses and realized large-scale industrialization in the Wanhua Ningbo industrial park, in which the newly-built equipment is successful for the first commissioning and operated stably. Compared with equipment of similar technologies, MDI equipment built with the technologies from this project requires low investment, low consumption and yields high quality, thus obtaining strong competitiveness, which indicates that MDI (the most important raw material in China's polyurethane industry) production technology has reached international top-ranking level.

Wanhua supreme science and Technology Award

2013  Research on technologies in the whole industry chain of isophorone
2013 Research on technologies in the whole industry chain of isophorone

Isophorone diamine (IPDA) is a kind of aliphatic diamine with excellent performance, whose widest application is to produce isophorone diisocyanate (IPDI) through a reaction with phosgene.

In addition, it can also be used as the raw material in the synthesis of polyamide and as an epoxy curing agent with excellent performance. Research on technologies in the whole industry chain of isophorone mainly include the research and development of three key technologies: isophorone (IP), isophorone nitrile (IPN) and isophorone diamine (IPDA).Development of each technology is a global challenge. In 2007, Wanhua officially launched research on technologies in the whole industry chain of isophorone. After seven years of technical study, three sets of pilot-plant technological process (IP, IPN, IPDA) designed and developed by our researchers were completed at the end of 2013 and produced qualified IP, IPN, IPDA products, which marked that Wanhua had fully mastered the core technologies in the whole industry chain of isophorone.

2011 new technology of manufacturing MDI through phosgenation reaction
2011 The fifth-generation new technology of manufacturing MDI through phosgenation reaction

MDI manufacturing mainly includes three parts: polyamine manufacturing, phosgenation, separation and purification, in which phosgenation reaction is the most critical link.The energy consumption in traditional phosgenation technological processes accounts for over 60% of the total consumption of MDI manufacturing. Because the phosgenation reaction has rapid reaction speed and a complicated gas-liquid-solid three-phase reaction system, the technological development is recognized as the most complicated link in MDI manufacturing. The researchers at Wanhua focused on the development of the reactor and finally successfully developed new fifth-generation technology for phosgenation reactions with the new reactor as the core after five years of numerous pilot plant tests and industrial tests. The application of this technology increases the capacity of the single set of MDI equipment phosgenation reaction system of Wanhua from 200,000 tons/year to over 400,000 tons/year, sharply reduces the solvent dosage and reaches over 40% comprehensive energy saving, thereby establishing the leading position of Wanhua in worldwide MDI manufacturing field and enhancing the competitiveness and influence of Wanhua in international polyurethane industry.

2008 R & D of the manufacturing technology of ADI-series products
2008 Research and development of the manufacturing technology of ADI-series products

ADI is a general term of aliphatic isocyanates, with representative varieties like dicyclohexyl methane-4,4’-diisocyanate (H12MDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI), etc. ADI has a complex process and is difficult to be technologically developed, so that only a few enterprises in the world have been able to produce it in the past 60 years. The project named “research and development of ADI-series products of Wanhua” lasted ten years from project approval to a significant technological breakthrough with arduous research and development. In 2009, a kiloton ADI pilot-plant designed and developed by the researchers at Wanhua was completed and successfully implemented in the first commissioning, and produced qualified H12MDI, HDI and IPDI products successively. Since then, Wanhua has successfully opened the door to ADI-series products manufacturing.
