Description
2-(Dimethylamino)ethyl methacrylate, also known as DMAEMA, is a colorless liquid with amine properties. It is less dense than water, insoluble in water, and has vapors heavier than air. DMAEMA is known to be corrosive to eyes and mucous membranes and can polymerize exothermically if heated or contaminated. It is toxic by skin absorption, ingestion, and inhalation, and produces toxic oxides of nitrogen during combustion. DMAEMA is primarily used in the production of plastics and textiles.

Air & Water Reactions
Insoluble in water.
Reactivity Profile
2-(Dimethylamino)ethyl methacrylate is both an amine and an ester. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Safety Profile
Poison by
intraperitoneal route. Moderately toxic by
ingestion and inhalation. A skin eye, and
mucous membrane irritant. A powerful
lachrymator. Flammable when exposed to
sparks, heat, open flame, or oxidizers. To
fight fire, use alcohol foam, dry chemical,
spray. When heated to decomposition it
emits toxic fumes of NOx. See also
ESTERS.
Check Digit Verification of cas no
The CAS Registry Mumber 2867-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2867-47:
(6*2)+(5*8)+(4*6)+(3*7)+(2*4)+(1*7)=112
112 % 10 = 2
So 2867-47-2 is a valid CAS Registry Number.

, p. 3818 - 3820 (2015)
3-[N-(2-Methacroyloylethyl)-N,N-dimethylamino]propane sulfonate (DMAPS) was synthesized by the ring-opening reaction of 1,3- propanesultone, then electrophilic substitution with 2-(dimethylamino)ethyl methacrylate in the presence of acetone at 60 °C. 2-(Dimethylamino)ethyl methacrylate and a little polymerization inhibitor dissolved in acetone was added in three-necked flask, the mixture was heated to 60 °C. 1,3-Propanesultone was dissolved in acetone and then be added drop-wise into the flask over 8 h. The product was characterized by NMR and Mass spectrum. The crystal structure of 3-[N-(2-Methacroyloylethyl)-N,N-dimethylamino]propane sulfonate was investigated using X-ray diffraction and SHELXTL97 software and the result indicated that DMAPS crystallized in the orthorhombic system, space group P21/c with a = 14.6818(18), b = 7.1104(9), c = 14.9180(18) ?, V = 1548.5(3) ?3; Z = 4.

Multi-purpose polymers, methods and compositions
-
, (2008/06/13)
Disclosed are multi-purpose polymers that are the polymerization product of a monomer mixture comprising at least one amino-substituted vinyl monomer; at least one nonionic vinyl monomer; at least one associative vinyl monomer; at least one semihydrophobic vinyl surfactant monomer; and, optionally, comprising one or more hydroxy-substituted nonionic vinyl monomer, crosslinking monomer, chain transfer agent or polymeric stabilizer. These vinyl addition polymers have a combination of substituents, including amino substituents that provide cationic properties at low pH, hydrophobic substituents, hydrophobically modified polyoxyalkylene substituents, and hydrophilic polyoxyalkylene substituents. The polymers provide surprisingly beneficial rheological properties in acidic aqueous compositions, and are compatible with cationic materials. The multi-purpose polymers are useful in a variety of products for personal care, health care, household care, institutional and industrial care, and industrial applications.
