Abstract

Способ получения 3-метил-5-нитро-тетрагидро-1,3-оксазина взаимодействием 2-гидроксиметил-2-нитропропандиола-1,3 с формальдегидом и метиламином в водной среде в присутствии в качестве катализатора карбоната натрия при нагревании, отличающийся тем, что, с целью повышения выхода целевого продукта и упрощения технологии процесса, нагревание проводят при 75 - 80C.The method of producing 3-methyl-5-nitro-tetrahydro-1,3-oxazine by reacting 2-hydroxymethyl-2-nitropropanediol-1,3 with formaldehyde and methylamine in an aqueous medium in the presence of sodium carbonate as a catalyst when heated, characterized in that , in order to increase the yield of the target product and simplify the process, heating is carried out at 75 - 80C.
