33327-41-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33327-41-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33327-41:
(7*3)+(6*3)+(5*3)+(4*2)+(3*7)+(2*4)+(1*1)=92
92 % 10 = 2
So 33327-41-2 is a valid CAS Registry Number.

Monoacylphosphine oxides with substituents in the phosphonyl moiety as Norrish I photoinitiators: Synthesis, photoinitiattion properties and mechanism

Duan, Haodong,Gao, Jun,Han, Yuxi,Leng, Kangwei,Li, Qianmin,Liu, Dayong,Wang, Zhongwei,Xu, Xiaolei,Yu, Qing

, (2021/09/07)

In order to study the effect of the substituents in the phosphonyl moiety of monoacylphosphine oxide (MAPO) on its stability and initiation performance, (2,4,6-trimethylphenyl)(phenyl)(benzoyl)phosphine oxide (TMBPO), (4-tolyl)(phenyl)(2,4,6-trimethylbenzoyl)phosphine oxide (4-MTPO) and (2,4-xylyl)(phenyl)(2,4,6-trimethylbenzoyl)phosphine oxide (2,4-DMTPO) were designed and prepared. Studies on TMBPO showed that the introduction of methyl groups into the phosphonyl moiety of MAPO significantly enhanced its stability and light absorption abilities. The photopolymerization of trimethylolpropane triacrylate (TMPTA) showed that the initiation efficiency of 4-MTPO and 2,4-DMTPO were higher than that of TPO, regardless of whether it was initiated upon LED at 385 nm or 420 nm. In addition, the migration rates of 4-MTPO and 2,4-DMTPO in cured TMPTA were approximately 1/2 and 1/4 that of TPO, respectively.

Chlorosilane-Catalyzed Coupling of Hydrogen Phosphine Oxides with Acyl Chlorides Generating Acylphosphine Oxides

Zhang, Jian-Qiu,Han, Li-Biao

supporting information, p. 4633 - 4637 (2020/06/23)

We report a new method for the synthesis of acylphosphine oxides by the direct coupling of hydrogen phosphine oxides and acyl chlorides mediated by chlorosilanes. This new protocol is greener and safer, because it precludes the generation of volatile haloalkanes and the use of oxidants employed in the conventional methods. Moreover, moisture-unstable acylphosphine oxides that are difficult to prepare via the conventional methods can be generated using this new method.

Continuous preparation method of trimethylbenzoyl-diphenylphosphine oxide compound

-

, (2019/10/07)

The invention discloses a continuous preparation method of trimethylbenzoyl-diphenylphosphine oxide (TPO) and its derivatives. The preparation method comprises: in a tubular reactor, benzaldehyde or its derivative reacts with chlorodiphenyl phosphine or its derivative; and then a catalytic oxidation reaction is directly carried out without separation, and the reaction solution is desolvated and re-crystallized to obtain a TPO product. The conversion rate of the product TPO is 98% and above, and the finished product content reaches 99.5% and above.
