Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide 75980-60-8
Category : Paint and Coatings/Inks and Printing Oil
CAS NO : 75980-60-8 EC NO : 278-355-8 MF : C22H21O2P MW : 348.3747 Specification : 99% min Packing : 25kg 50kg drum or bag Product description : What is the chemical of Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide? 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： This product is the optimal extraction solvent for petroleum aromatic hydrocarbon plants; A mixed solution of N-formylmorpholine and morpholine (1:1) is the extraction solvent for the methyl ethyl ketone unit. Also used as a formylation reagent in the field of fine chemicals, it is mainly used as a photo initiator for screen printing ink, lithographic printing ink, flexographic printing ink, and wood coating applications. It is used in various ink industries and is mostly used in white systems. It can be used for UV curing coatings, printing inks, UV curing adhesives, optical fiber coatings, and other applications. UV curing coatings and inks are used for UV curing coatings and inks Usage: Mainly used in UV curing systems (such as coatings, inks, adhesives, 3D printing resins, dental materials), especially suitable for white/light/thick film systems and UV-LED (395 nm) light sources; Has wide absorption (250-420 nm, λ ₘₐₓ ≈ 380 nm), photobleaching effect (low yellowing after curing), strong deep curing ability, and low odor characteristics; Commonly used in screen printing/flexographic ink, wood/metal UV paint, electronic glue, optical fiber coating, etc. ============================================================================ Synthesis route: The mainstream industrial method uses 2,4,6-trimethylbenzal-dehyde and diphenylphosphine oxide as raw materials, and is obtained through oxidation condensation reaction in the ammonium metavanadate/hydrogen peroxide catalytic system (yield about 98%); Another patented route involves the chlorination of diphenylphosphate to obtain diphenylphosphonic chloride, which is then condensed with 2,4,6-trimethylbenzyl magnesium chloride (Grignard reagent) and oxidized to produce a resource recycling process. Uses : This product is the optimal extraction solvent for petroleum aromatic hydrocarbon plants; A mixed solution of N-formylmorpholine and morpholine (1:1) is the extraction solvent for the methyl ethyl ketone unit. Also used as a formylation reagent in the fie Synonyms : 2,4,6-Trimethylbenzoyldiphenyl Phosphine Oxide;2,4,6-Trimethylbenzoyldiphenylphosphine oxide;TPO;Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide;Photoinitiator-TPO;(diphenylphosphoryl)(2,4,6-trimethylphenyl)methanone;Diphenyl (2,4,6-trimethylbenzoyl)-phosphine oxide;(2,4,6-trimethyl benzoyl) diphenyl phosphine oxide;Photoinitiator TPO;Trimethyl-Benzoyl-Diphenyl-Phosphine-oxide; Molecular Structure :
