Issue 1, 2017 - Silverlight Group successfully synthesizes M-XDI

Silverside Group successfully synthesized M-XDI In December 2016, China North Industries Group Gansu Yinguang Chemical Industry Group Co.
, Ltd.
synthesized isophthalate isocyanate (M-XDI
) with a purity of 99.
58%, which reached the international qualified product standard of 99.
5% purity, which marked a breakthrough in the company's research project on small-scale synthesis of isophthalate isocyanate
.

M-XDI is a polyurethane raw material, its products have light stability, yellowing resistance and other properties, mainly used in the field of high-grade polyurethane spectacle lenses, but also in the form of XDI-TMP, XDI trimer curing agent used in high-grade polyurethane coatings, flexible packaging, outdoor sealants, elastomers, leather and adhesives and other fields
.
At present, the world's main manufacturer is Japan's Mitsui Chemicals, and domestic downstream manufacturers are completely dependent on imports to meet their production needs
.
As the first Yinguang Group in China to introduce complete sets of process equipment and successfully produce TDI products, it has been continuously accelerating the transformation of China's TDI scientific and technological achievements into production capabilities for a long time, promoting the road of independent development in TDI's major scientific and technological fields, and extending and expanding the polyurethane industry chain
.

The successful research and development of isophthalene isocyanate of Silvergroup has broken the technical monopoly of foreign M-XDI manufacturers on M-XDI production, and provided a theoretical basis
for the next step of M-XDI kilogram research and subsequent pilot design.
While enriching the variety of small isocyanate products, it has further improved the research and development capabilities of small isocyanate products and the independent innovation ability
of enterprises.
