FIELD: chemistry.
SUBSTANCE: invention relates to a method for preparing urea-containing silanes. Method for preparing urea-containing silanes of general formula (I) is proposed, where R1 have the same or different values and represent C1-C10-alkoxy groups or a phenoxy group, R have the same or different values and represent an unbranched saturated aliphatic divalent hydrocarbon group with C1-C30, that the diamine of general formula (II) is reacted in water with an isocyanatosilane of general formula III.
,
EFFECT: technical result is the proposed method allows to avoid the use of an organic solvent and contains fewer steps than known methods.
