METHOD FOR PRODUCING OLIGO-2,2-BIS(AZIDOMETHYL)OXIRANS Russian patent published in 2021 - IPC C07C247/04 C08G65/325 C08G65/08

Abstract RU 2757594 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing oligo-2,2-bis(azidomethyl)oxiranes of the formula H-[OCH₂(CH₂N₃)₂C-]_n-O-R-[OCH₂(CH₂N₃)₂C-]_nOH (II), where n=2, 4÷10, R=CH₂CH₂OCH₂CH₂, which consists in the azidation of oligo-2,2-bis(chloromethyl)oxiranes of the formula H-[OCH₂(CH₂Cl)₂C-]_n-O-R-[OCH₂(CH₂Cl)₂C-|_nOH (I), where n=2, 4÷10, R=CH₂CH₂OCH₂CH₂, using tetrabutylammonium chloride as a catalyst for interphase transfer, followed by precipitation of the reaction mixture into water, extraction of the target product with methylene chloride and its further distillation.

EFFECT: method for producing oligo-2,2-bis(azidomethyl)oxiranes of the formula (II) is developed, which can be used as plasticizers, binders to create highly effective compositions with an increased value of energy characteristics.
