3881-14-9 Usage
General Description
Triethyloctadecylammonium bromide is a quaternary ammonium compound that is commonly used as a surfactant and antistatic agent in various industrial and commercial applications. It is a cationic surfactant with a long hydrophobic tail and a positively charged head group, making it effective at lowering surface tension and stabilizing emulsions. Triethyloctadecylammonium bromide is also known for its ability to form micelles in solution, which can aid in solubilizing hydrophobic molecules. Additionally, it has been used in research for its antimicrobial properties and as a component in pharmaceutical formulations. However, its use can be associated with potential health and environmental hazards, requiring careful handling and disposal practices.
Check Digit Verification of cas no
The CAS Registry Mumber 3881-14-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,8 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3881-14:
(6*3)+(5*8)+(4*8)+(3*1)+(2*1)+(1*4)=99
99 % 10 = 9
So 3881-14-9 is a valid CAS Registry Number.

A general strategy for the rational design of size-selective mesoporous catalysts
Zapilko, Clemens,Liang, Yucang,Nerdal, Willy,Anwander, Reiner
, p. 3169 - 3176 (2008/02/05)
A series of functionalized mesoporous silicas with cagelike pore topology has been synthesized and screened for size-selective catalytic transformations. The aluminum-catalyzed Meerwein-Ponndorf-Verley (MPV) reduction of differently sized aromatic aldehydes (benzaldehyde and 1-pyrenecarbox-aldehyde) has been investigated as a test reaction. The catalysts were synthesized in a two-step grafting sequence comprising pore-size engineering of mesoporous silicas (SBA-1, SBA-2, SBA-16) with longchain alkyl dimethylaminosilanes and surface organoaluminum chemistry with triethylaluminum [{Al-(CH2CH 3)3)2]. Size-selective reaction behavior was found for small pore SBA-1 materials, and the selectivity could be efficiently tuned by selecting a silylating reagent of appropriate size. The results are compared with the catalytic performance of a large-pore periodic mesoporous organosilica PMO-[SBA-1] and the nonporous high-surface-area silicas Aerosil 300/380.
