Sigma-Aldrich 异丙基-9H-噻吨-9-酮（2、4位异构体混合物），百分之九十七

产品概述

异丙基噻吨酮（ITX）是一种噻吨酮衍生物，广泛用作聚合过程中的光引发剂。它是2-和4-异构体的混合物。它在暴露于紫外线辐射时分解成自由基，引发UV固化油墨、木材涂料、纸张涂料、光纤、丝网印刷和纸张清漆中的聚合。

应用领域

Isopropylthioxanthone can be used as: A photoinitiator along with azolium tetraphenylborate to N-heterocyclic carbene (NHC) generation in the synthesis of polyurethane, polyester, and ROMP (ring-opening metathesis polymerization) polymers. The mixture of ITX and azolium tetraphenylborate serves as an air-stable NHC photogenerator, activated by irradiation at 365 nm. A photocatalyst to facilitate the functionalization of bicyclo[1.1.0]butanes. This approach allows for the introduction of various functional groups onto the bicyclo[1.1.0]butane framework. A sensitizer that absorbs light and transfers energy to di(tert-butylphenyl)iodonium salts, facilitating their photolysis. This process generates reactive species necessary for initiating polymerization reactions. This sensitization approach is useful in various fields, including coatings, adhesives, and dental materials, where controlled polymerization is essential.
