Dodecylmethylammonium chloride (DMAC) is a cationic surfactant with the chemical formula C19H40ClN. It is a quaternary ammonium compound derived from dodecylamine and methyl chloride, featuring a long hydrocarbon chain and a positively charged nitrogen atom. DMAC is widely used in various applications, including as a fabric softener, antimicrobial agent, and phase-transfer catalyst. It exhibits excellent solubility in water and organic solvents, and its amphiphilic nature allows it to lower surface tension and form micelles. Due to its cationic nature, DMAC can interact with negatively charged surfaces, making it useful in water treatment and as a flocculant. However, it is important to note that DMAC can be toxic to aquatic life and should be handled with care.

Check Digit Verification of cas no

The CAS Registry Mumber 2292-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2292-50:
(6*2)+(5*2)+(4*9)+(3*2)+(2*5)+(1*0)=74
74 % 10 = 4
So 2292-50-4 is a valid CAS Registry Number.

Effect of the N-Methylation of Dodecylammonium Chloride on the Adsorption from Its Micellar Solution

Aratono, Makoto,Okamoto, Toru,Ikeda, Norihiro,Motomura, Kinsi

, p. 2773 - 2778 (2007/10/02)

The surface tension of the aqueous solution of dodecylmethylammonium chloride (DMAC) and dodecyldimethylammonium chloride (DDAC) was measured as a function of temperature under atmospheric pressure at concentrations below and above the critical micelle concentration (cmc).The entropy and energy of adsorption from the monomeric state in the aqueous solution and the micellar state were evaluated by applying the thermodynamic equations of adsorption to the surface tension values.The thermodynamic quantities were compared with those of the aqueous solutions of dodecylammonium chloride (DAC) and dodecyltrimethylammonium chloride (DTAC).It was found that the successive N-methylation of DAC has a considerable effect on the adsorbed film with changes in its surface density, entropy, and energy brought about by changes in the geometry and the hydrophilicity of the polar head group.
