CAS NO : 105-16-8 EC NO : 203-275-7 MF : C10H19NO2 MW : 185.2634 Specification : 99% min Packing : 25kg 50kg 200kg net drum Product description : What is the chemical of N,N-Diethyl-aminoethyl methacrylate ? Appearance:colorless transparent liquid Assay：99% min by GC IR Identity: conform to standard HNMR： conform to standard carbon spectrum: conform to standard Water by K. F.:0.5% max or as per the customer’s request Loss on drying:0.5% max. or as per the customer’s request ============================================================================= main purpose Diethylaminoethyl methacrylate has unique advantages in polymer modification due to the presence of both polymerizable double bonds and hydrophilic tertiary amine groups in its molecule. Its main applications include: Leather treatment agent: improves the softness, anti-static properties, and dye adsorption capacity of leather, enhancing dyeing uniformity. Thermosetting coatings and adhesives: As crosslinking monomers, they enhance coating adhesion, water resistance, and thermal stability. Antistatic agent: used for surface treatment of plastics and fibers to reduce surface resistance and prevent static electricity accumulation. Dyeing auxiliaries: used as cationic auxiliaries in textile printing and dyeing to improve the affinity of acidic dyes to polyamide fibers. Lubricant additives: enhance the extreme pressure anti-wear performance and clean dispersibility of oil products. Ion exchange resin and functional polymer: used for synthesizing cationic resins, applied in water treatment, chromatographic fillers, and drug sustained-release carriers. Medical polymer materials: used to prepare biocompatible hydrogels, dental materials and drug controlled release systems. =========================================================================== synthetic route The industrial synthesis of diethylaminoethyl methacrylate mainly adopts esterification reaction method, using methacrylic acid and diethylaminoethanol as raw materials, and conducting condensation dehydration under the action of catalyst: Reaction equation: CH2=C (CH3) COOH+HOCH2CH2N (C2H5) 2 → Catalyst/Δ CH2=C (CH3) COOCH2CH2N (C2H5) 2+H2OCH 2=C (CH 3) COOH+HOCH2CH 2N (C2H5) Catalyst/Δ CH 2=C (CH 3) COOCH 2CH 2N (C2H5) 2+H2O Key points of the process: Raw materials: Methacrylic acid (purity ≥ 99%), diethylaminoethanol (purity ≥ 98%) Catalyst: p-toluenesulfonic acid, sodium bisulfate or solid acid catalyst Reaction temperature: 100-140 ° C Dehydration method: vacuum distillation or azeotropic dehydration (such as using toluene as a water carrying agent) Post treatment: Neutralization, water washing, vacuum distillation purification, addition of stabilizer (MEHQ 50-100 ppm) to prevent polymerization Yield: Industrial grade yield can reach 85-92% This route has mature technology and controllable cost, and is currently the mainstream industrial production method. Uses : Used for preparing thermosetting coatings, anti-static agents, dyeing auxiliaries, adhesives, etc Has amino reactivity and vinyl polymerization, which can improve crosslinking and coloring properties Synonyms : 2-Diethylaminoethyl methacrylate; 2-Propenoic acid, 2-methyl-, 2-(diethylamino)ethyl ester; Diethylaminoethyl methacrylate; METHACRYLIC ACID 2-DIETHYLAMINOETHYL ESTER (STABILIZED WITH MEHQ);2-(diethylamino)ethyl 2-methylprop-2-enoate;2-(diethylamino)ethyl 2-methylprop-2-enoate hydrochloride (1:1);1-(diethylamino)ethyl 2-methylprop-2-enoate;2-(Diethylamino)ethyl methacrylate;DEAM; Molecular Structure :
