Allyl glycidyl ether → Glycidoxypropyltrimethoxysilane

Participants

Reaction Steps

In the example, allyl glycidyl ether was reacted with trimethoxysilane to form 3-glycidyloxypropyltrimethoxysilane. The reaction was carried out continuously by feeding the raw materials (allyl glycidyl ether: 9.6 kg/h and trimethoxysilane: 8 kg/h) together with the Pt Karstedt catalyst in the presence of acetic acid (0.05% by weight, based on the total mass of reactants) into a tube reactor. The concentration of the catalyst based on metallic platinum was 2 ppm. The Pt Karstedt catalyst was dissolved in 3-glycidyloxypropyltrimethoxysilane. The reaction temperature was about 160° C. The reaction was carried out using an excess of allyl glycidyl ether (molar ratio of allyl glycidyl ether:trimethoxysilane=1.28:1). The reaction mixture formed was composed of:
