2-Methyl-4'-(Methylthio)-2-Morpholinopropiophenone is an efficient UV photoinitiator for initiating UV polymerization of unsaturated prepolymer systems, Such as acrylic resins and monofunctional and multifunctional vinyl monomers. The initiator molecule has a certain light absorption capacity in the ultraviolet region (250-400 nm) or the visible region (400-800 nm). After direct or indirect absorption of light energy, the initiator molecules transition from the ground state to the excited singlet state, through intersystem conversion to excited triple state. After undergoing a single molecular or bimolecular chemistry, initiator molecules produce reactive debris that initiates polymerization of the monomers, which may be free radicals, cations, anions, etc. According to the different initiation mechanism, the photoinitiator can be divided into free radical polymerization photoinitiator and cationic photoinitiator, among which the most widely used is free radical polymerization photoinitiator. The characteristic of high absorbency of 2-Methyl-4'-(Methylthio)-2-Morpholinopropiophenone makes it particularly suitable for UV curable inks and colored coatings. UV inks contain a greater amount of photoinitiator, and it is these photoinitiators that promote the rapid drying of the ink during the printing process. These photoinitiators themselves are not stable, even in the dark, and it is also prone to dark reaction, resulting in one by one ink glue nucleus, followed by a large area of retrogradation. Especially in the preservation of metal ink, similar situation occur more often. Therefore, it is recommended that the ink pigment and the binder separately stored. If used, stir and mix the two with a large machine.
Highly efficient photoinitiator can be used in UV curing systems to extend storage with non-yellowing for a long time. It is an initiator specifically for pigmented UV-curable coatings, inks and adhesives colored solidification system, and it could be used with184, ITX and other initiators. It can be used for colored ink systems, paper/metal and plastic varnish and electronic inks. It is also as a UV absorber for cosmetics and other industries with suggested supplementation of 2-6%.

Check Digit Verification of cas no
The CAS Registry Mumber 71868-10-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,6 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71868-10:
(7*7)+(6*1)+(5*8)+(4*6)+(3*8)+(2*1)+(1*0)=145
145 % 10 = 5
So 71868-10-5 is a valid CAS Registry Number.

Preparation method of 2-methyl-1-(4-substituted phenyl)-2-morpholinyl-1-acetone
-
, (2021/03/30)
The invention relates to a preparation method of 2-methyl-1-(4-substituted phenyl)-2-morpholinyl-1-acetone. The preparation method comprises two steps of epoxidation reaction and morpholine substitution reaction, wherein in the morpholine substitution reaction, a proper amount of an auxiliary agent is added, and the auxiliary agent is selected from at least one of water, a strong-acid weak-alkalisaline solution and a strong-alkali weak-acid saline solution, so that the ring opening rate and the ring opening selectivity in the morpholine substitution reaction process can be obviously improved,and the overall reaction rate and yield are further improved, according to the method, the problem that subsequent catalysts are difficult to filter, recycle and purify due to the fact that catalystssuch as carclazyte need to be added in the traditional process is solved, the high-purity 2-methyl-1-(4-substituted phenyl)-2-morpholinyl-1-acetone can be obtained more easily, the process cost and the aftertreatment operation risk are reduced, and the economic benefit is improved.
