Abstract
PURPOSE: To obtain the titled compound useful as an improver for physical properties of composite materials, etc., by reacting a chloroalkylsliane with ethylenediamine in a molar ratio 1:6 not less than, followed by distilling away a specific amount of excess diamine.
CONSTITUTION: A chloroalkylsilane shown by the formula I (R is 1W4C alkyl; R' is 1W6C alkyl or alkoxyalkyl m is 1,2, or 3; a is 0 or 1) is reacred with ethylenediamine (EDA for short) in a molar ratio of not less than 1:6, and after the reaction excess EDA is distilled away out of the reaction system. The reaction solution is separated into two layers in such a way that a molar ratio of an amount of EDA to an amount of the compound shown by the formula I used in the reaction becomes 2.5W5.0. A compound shown by the formula II is obtained in high yield in high purity by separating a layer containing EDA hydrochloride.
EFFECT: The formation of a bissilyl derivative is suppressed by making a molar ratio of a chloroalkylsilane to EDA 1: not less than 6.
