29508-45-0 Usage
General Description
Dimethyldiethylammonium chloride, also known as DEDMA, is a quaternary ammonium compound commonly used as a cationic surfactant and a phase transfer catalyst in organic synthesis. It is a clear, colorless to yellowish liquid with a faint amine-like odor. DEDMA is highly soluble in water and is often used in industrial processes as a disinfectant, a corrosion inhibitor, and a catalyst for organic reactions. It is also used in the production of personal care products, pesticides, and disinfectants. DEDMA is considered to be relatively low in toxicity and is not classified as a carcinogen or mutagen, but it should still be handled with caution and in accordance with proper safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 29508-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,0 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 29508-45:
(7*2)+(6*9)+(5*5)+(4*0)+(3*8)+(2*4)+(1*5)=130
130 % 10 = 0
So 29508-45-0 is a valid CAS Registry Number.

Alkylation of ammonium salts catalyzed by imidazolium-based ionic liquid catalysts
Zheng, Zhuo Qun,Wang, Jie,Wu, Ting Hua,Zhou, Xiao Ping
, p. 1095 - 1101 (2008/03/27)
Quaternary ammonium salts were synthesized from ammonium salts and dialkyl carbonates over imidazolium ionic liquid catalysts. The reaction gave almost stoichiometric amounts of the quaternary ammonium salts for halides and nitrates. It was found that the electron-donating property of the alkyl moieties of ammonium cations, the electrophilic nature of the alkyl group of the carbonate, the acidity of the acid that the anion of the ammonium salt corresponds to, and the steric hindrance of the ammonium salts and the dialkyl carbonates are the key factors that influence the yields of quaternary ammonium salts. Strong electron-donating alkyl groups on the nitrogen atom of the ammonium salt, electron-withdrawing groups on the methylene carbon of dialkyl carbonate, and weaker steric hindrance of the starting ammonium salts and dialkyl carbonates favor the alkylation reaction of ammonium salts.
