Flammability and Explosibility

Nonflammable

Check Digit Verification of cas no

The CAS Registry Mumber 75980-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,8 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75980-60:
(7*7)+(6*5)+(5*9)+(4*8)+(3*0)+(2*6)+(1*0)=168
168 % 10 = 8
So 75980-60-8 is a valid CAS Registry Number.

Effective Catalyst for Oxidation Synthesis of 2,4,6-Trimethylbenzoyldipenylphosphine Oxide: V/MCM-41

Wang, Tingting,Wang, Zhiming,Zhao, Junjing,Yu, Qing,Wang, Zhongwei

, p. 953 - 957 (2018)

Abstract: 2,4,6-Trimethylbenzoyldipenylphosphine oxide (TPO) is an important photoinitiator, nevertheless some drawbacks exist in its synthesis. So V/MCM-41 catalysts were designed. Compared with commonly used VO(acac)2, V/MCM-41 catalysts exhi

Co-production preparation of monoacylphosphine and bisacylphosphine and oxides thereof

-

Paragraph 0056; 0057, (2021/11/19)

The invention relates to the field of photocuring functional new material chemicals, discloses co-production preparation of a series of monoacylphosphine and diacylphosphine, and oxides thereof, namely monoacylphosphine oxide and diacylphosphine oxide for the first time, wherein one-pot preparation of the compounds in the same flow process and the same reactor is achieved for the first time. The process technology has the characteristics of outstanding low-cost economic competitiveness and environmental friendliness. The compounds are important olefinic bond (C=C)-containing unsaturated photoinitiator for a radiation polymerization system.

High performance liquid phase continuous automatic production and co-production technology of organic phosphine compound

-

, (2021/05/12)

The invention relates to the field of photocuring functional new material chemicals, and discloses a high performance liquid phase streamline type continuous automatic production technology of an acylphosphine oxide organic phosphine compound for the first time, which not only can produce a single specific target product, but also can co-produce a product mixture of two or more than two of the products of the type. The process technology has outstanding low-cost economic competitiveness and environment-friendly characteristics for large-scale manufacturing of target products. The target product comprises sym-trimethylbenzoyl diphenyl phosphine oxide (also known as 2, 4, 6-trimethylbenzoyl diphenyl phosphine oxide, trade name TPO), sym-trimethylbenzoyl phenyl ethyl phosphonate (trade name TPO-L) and structural analogues thereof, and a mixture of the sym-trimethylbenzoyl diphenyl phosphine oxide and the sym-trimethylbenzoyl phenyl ethyl phosphonate. The organic phosphine compound is an olefinic bond-containing (C=C) unsaturated radiation polymerization system photoinitiator and/or flame retardant and the like with wide application.
