Dodecyl 2-methylacrylate Usage And Synthesis

Chemical Properties	clear colorless to yellowish liquid
Uses	Miniemulsion polymerization of laurel methacrylate has been reported. Atom transfer radical polymerization and consecutive block copolymerization with methyl methacrylate has been investigated. Preparation of LMA based monolithic columns for CEC has been reported. LMA is used as a co-stabilizer to retard Ostwald ripening effect.
General Description	Liquid. Floats on water.
Reactivity Profile	Dodecyl 2-methylacrylate is an ester. 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. Tends to polymerize. Oxidizing and reducing agents may initiate polymerization. Reaction may also occur when heated [USCG, 1999].
Health Hazard	Inhalation temporarily reduces blood pressure from 5 to 25%, increases respiratory rate, decreases heart rate, and causes some EKG changes. Liquid may cause irritation of eyes and skin. May be harmful if swallowed.
Fire Hazard	Behavior in Fire: Heat can induce polymerization with rapid release of energy. Sealed containers may rupture explosively.
Flammability and Explosibility	Nonflammable
Purification Methods	Purify the ester by fractional distillation in a high vacuum. Add 0.05% of hydroquinone monomethyl ether as stabilizer. [Rehberg & Fischer Ind Eng Chem 40 1430 1948, Beilstein 2 III 1290, 2 IV 1528.]
