What is Irgacure 651?
Irgacure 651 (English common name: 2, 2-Dimethoxy-2_phenylacetophenone), molecular formula C16H16O3, Chinese aliases: benzoin dimethyl ether, photoinitiator BDK, photoinitiator 651. The appearance of benzoin dimethyl ether is white crystal, melting point 61~63°C, insoluble in water, soluble in acetone, chloroform, ethanol, ether and other organic solvents.
2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator used to launch totally free extreme polymerization, such as in the prep work of acrylate polymers. Under the influence of light, particles will create complimentary radicals that start extreme polymerization. It can likewise be used as an initiator in the process of making integrated circuits.
Irgacure 651 Uses
2,2-Dimethoxy-2-phenylacetophenone (cas# 24650-42-8) is a compound useful in organic synthesis.
Irgacure 651 is generally made use of as a photocuring agent for UV curing systems, made use of in inks, paper as well as steel paints.
Irgacure 651 is widely made use of in the polymerization of acrylates as well as monomers and also the polymerization and also crosslinking of unsaturated polyesters. It has been applied in finishings as well as adhesives.

Application of Irgacure 651
Irgacure 651 is widely used for polymerization of acrylic acid and acrylate, polymerization and crosslinking of unsaturated polyester. It is applied to coatings and adhesives, mainly used as UV (ultraviolet) curing agent in UV curing system, and applied to ink, paper and metallic paint.
BDK is an efficient UV curing initiator, mainly used as an initiator for UV curing reaction. Also used as:
- Used as analytical reagent;
- Used for photosensitive resin printing;
- Used as UV curing coating and ink.
Preparation of Irgacure 651
“Synthesis and Properties of Benzoin Dimethyl Ether (Irgacure)” (“Image Material” No. 5, 1984, Zhang Baolin, Su Cuihua, Yang Jingping, Yu Shangxian) discloses a synthetic method of benzoin dimethyl ether (Irgacure), using benzyl , dimethyl sulfate, and sodium methoxide as raw materials to synthesize benzoin dimethyl ether. The method is cumbersome to operate, produces more waste water, and has a lower yield of only 55%, which does not meet the requirements of industrial production.
U.S. Patent US4967010A discloses a synthetic method of benzoin dimethyl ether, using benzil, dimethyl sulfate, sodium methoxide, and sodium hydroxide as raw materials and N, N-dimethylpropenylurea as a catalyst to synthesize benzoin dimethyl ether Ether, the method uses many kinds of reagents, and dimethyl sulfate is highly toxic, sodium methoxide is difficult to store and transport, N, N-dimethylpropenyl urine is expensive, and the post-treatment method is complicated, which is not conducive to industrial production.
U.S. Patent No. 5,081,307 discloses a synthetic method of benzoin dimethyl ether, using benzyl, dimethyl sulfate and sodium methylate as raw materials, in a nonpolar solvent, using a single or mixed catalyst, polyethylene glycol, poly One or more mixtures of ethylene glycol dialkyl ethers and crown ethers. It is troublesome to use potassium carbonate and trimethyl phosphite in the post-treatment process of this method, and a large amount of water is used for washing, and the amount of waste water produced is relatively large, which is not conducive to industrial production.
