Abstract

FIELD: methacryl acid derivatives' production. SUBSTANCE: N,N'-methylene- bis-methacrylamide is prepared by heating methacrylamide with formaldehyde at mole ratio 2:1 in presence of organic solvent and catalyst followed by isolating and filtering off the product. Improvement consists in that as a solvent water azeotrope-forming alifatic and aromatic hydrocarbons are used at molar hydrocarbon to methacrylamide ratio (0.5-1.5):1, and synthesis is carried out gradually: stoichiometric amounts of reactants are heated in presence of 0.8-1% (in respect to amide) of alkali at 50-55 C for 15-20 min followed by adding remaining amount of methacrylamide and 0.5-0.6% (based on total weight of reactants) of sulfuric acid and keeping the solvent boiling until reaction water is completely removed. EFFECT: increased yield, simplified product isolation.
