实验步骤: In a 5 liters four-necked flask equipped with a stirrer, a thermometer, a gas-inlet tube, and a condenser were placed 1000 g (4.0 moles) of 1,3-bis(3-aminopropyl)-1,1,3,3-tetra-methyldisiloxane having a gas chromatography purity of 98.4%, and 2,600 g of isopropanol. 360 g (9.9 moles) of hydrogen chloride gas was bubbled into the solution while stirring the mixture at room temperature. Recrystallization was conducted to obtain 1,250 g (yield: 97%) of 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane dihydrochloride which was an acid addition salt.
