The invention relates to a method for producing oligoaminosilanes of the general formula (I) Si
n
Y
2n+2
, wherein oligohalosilanes of the general formula (II) Si
n
X
2n+2
are reacted with primary amines of the general formula (III) R—NH
2
in hydrocarbons as solvents, wherein X is selected from among chlorine, bromine, and iodine, Y is a halogen, hydrogen, or R—NH, R is a hydrocarbon group having 1 to 20 carbon atoms, and n is values from 1 to 20, with the stipulation that at most 35 mol % of the groups Y is a hydrogen and at most 15 mol % of the groups Y is a halogen, wherein activated carbon is added to the reaction mixture. The invention further relates to a method for stabilizing the oligoaminosilanes of the general formula (I), wherein the oligo ammosilanes are treated with activated carbon.
本发明涉及一种制备通式(I)SinY2n+2的寡聚氨基硅烷的方法,其中寡卤代硅烷通式(II)SinX2n+2与一次胺通式(III)R—NH2在烃类溶剂中反应,其中X从氯、溴和碘中选择,Y是卤素、氢或R—NH,R是具有1至20个碳原子的烃基,n的值为1至20,但最多35摩尔%的Y基团为氢,最多15摩尔%的Y基团为卤素,反应混合物中加入活性炭。本发明还涉及一种稳定通式(I)寡聚氨基硅烷的方法,其中寡氨基硅烷与活性炭处理。
