Potassium Hydroxide → potassium N-(2-aminoethyl)-3-aminopropylsilanolate

Participants

Reaction Steps

About 111 g of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (commercially available under the name "Silan GF 91" from Wacker-Chemie GmbH, Munich) are metered into a solution containing 95.g of potassium hydroxide in 400 g of water, with vigorous stirring. First methanol and then about 200 g of water are distilled off from the mixture by heating. The mixture is then made up to a total weight of 367 g by addition of water. A 40 percent potassium N-(2-aminoethyl)- 3-aminopropylsilanolate solution is obtained.
