2-Hydroxy-2-methylpropiophenone 7473-98-5
Category : Paint and Coatings/Inks and Printing Oil
CAS NO : 7473-98-5 EC NO : 231-272-0 MF : C10H12O4 MW : 196.1999 Specification : 99% min Packing : 25kg，50kg 200kg drum Product description : What is the chemical of 2-Hydroxy-2-methylpropiophenone ? Appearance:light yellow liquid Assay：99%min by GC 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: As a photoinitiator 1173, it is widely used in UV curing systems (such as wood/metal/plastic coatings, screen ink, 3D printing resins). It has the characteristics of low odor, no yellowing, and good compatibility with multifunctional monomers. It is often used in combination with TPO, 819, or 907. ============================================================================= Main synthesis route: Starting from isobutyrylbenzene (CAS 611-70-1), it undergoes aldol condensation with formaldehyde under alkaline conditions (such as NaOH/alcohol), or is prepared by alpha hydroxylation of acetophenone derivatives (such as using H ₂ O ₂/catalyst); The high-yield (~92%) route can be found in Liang&Jiao, Angew. Chem. 2014; There are also traditional methods such as via phenylethyl ketone and peroxide acid oxidation-reduction, but the efficiency is relatively low (~69%) Uses : As an efficient photoinitiator for UV curing systems, it is used for free radical polymerization reactions of materials such as coatings and inks.
