methacrylic acid-N, N'-dimethylaminoethyl Ester is colorless transparent viscous liquid; Relative density (25 ℃)0. 933; Boiling point (0.lMPa) 68.5 ℃; Flash Point (open) 64 ℃; Soluble in water, alcohols, esters, ethers, ketones, hydrocarbons and halogenated hydrocarbons and other solvents, the aqueous solution is alkaline; With olefins, characteristics of amines and esters; Under certain conditions can occur polymerization, addition and hydrolysis of chemical reactions; Flammable.
methacrylic acid-N,N'-dimethylaminoethyl Ester is obtained by esterification of methacrylic acid with dimethylaminoethanol or by transesterification of methacrylic acid with dimethylaminoethanol.
The copolymer of methacrylic acid-N, N'-dimethylaminoethyl Ester and higher alcohol methacrylate can not only improve the viscosity index of lubricating oil, but also has the purification dispersibility, nf one or two methyl ammonia ethyl ester and acrylamide copolymerization, water soluble copolymer, for three
Secondary oil recovery; Also used in high molecular flocculant, non-aqueous dispersant, antistatic agent, chlorinated polymer stabilizer, fiber treatment agent, rubber modifier, coating, ion exchange resin, paper processing and tear agent.
The product is bottled or bottled, stored in a cool place below 20 ° C, isolated from the fire source, in order to prevent polymerization, plus a polymerization inhibitor hydroquinone 0. 01% ~ 0. OS% in the product, the shelf life of 3 months.
