2,4-Diethyl-9H-thioxanthen-9-one 82799-44-8
Category : Paint and Coatings/Inks and Printing Oil
CAS NO : 82799-44-8 EC NO : 280-041-0 MF : C17H16OS MW : 268.3733 Specification : 99% min Packing : 25kg 50kg drum or bag Product description : What is the chemical of 2,4-Diethyl-9H-thioxanthen-9-one ? Appearance:light yellow powder Assay: 99%min by HPLC IR Identity: conform to standard HNMR： conform to standard carbon spectrum: conform to standard Water by K. F.:0.5% max or as per the customer’s request Loss on drying:0.5% max. or as per the customer’s request ===========================================================Usage: Mainly used as a UV light curing initiator, suitable for light curing systems of unsaturated polyester and acrylic monomers, widely used in inks, coatings (especially colored/white systems), adhesives, wood coatings, and printing finishes. It has the characteristics of strong absorption in the ultraviolet and visible light regions, good solubility with organic solvents, and low risk of yellowing; Also known as organic synthesis intermediates. ============================================================================ Synthesis route: The common method is the condensation cyclization of 1,3-diethylbenzene with dithiosalicylic acid (or its derivatives) under acid catalysis and high temperature, followed by dehydration and oxidation (such as air/O ₂) to construct a thioanthraquinone skeleton; There are also reports in the literature on the use of Friedel Crafts acylation or transition metal catalyzed coupling strategies, but the industrial mainstream still relies mainly on condensation cyclization methods (non-public detailed processes, mostly involving sealed tube reactions, catalysts such as Fe (NO3)), and other conditions) Uses : Photoinitiators widely used in the field of photopolymerization Core application: UV curable coating/ink photoinitiator, significantly improving curing efficiency and coating adhesion. Applicable fields: Wood coatings, metal printing, plastic surface trea Synonyms : Diethylthioxanthenone;DETX;2,4-Diethylthioxanthen-9-one;2,4-Diethylthioxanthone;Photoinitiator-DETX;Syna 448;Photoinitiators DETX;9h-thioxanthen-9-one,2,4-diethyl; Molecular Structure :
