Abstract
A composition containing 2-ethylhexyl silicate, is produced by heating a reaction mixture of ethyl silicate with an excess amount of 2-ethylhexanol in the presence of titanium tetrabutoxide as catalyst to a temperature below the boiling point of 2-ethylhexanol while mixing, allowing the reaction mixture to react and, after the reaction, removing ethanol and excess 2-ethylhexanol from the reaction mixture by distillation and obtaining the composition containing 2-ethylhexyl silicate.
