Procedure
Undecamethylpentasiloxanylundecylglyceryl ether (F) was obtained in a 48% yield in the same manner as Example 4. At this time, since 1,5-dihydrodecamethylpentasiloxane was included in a raw material of undecamethylpentasiloxane, 1,5-bis[11-(2,3-dihydroxypropoxy)undecyl]decamethylpentasiloxane (G) was obtained at the same time. The obtained compound (G) was isolated and refined by a silica gel column. The structures of the obtained products were confirmed by an analysis using IR and NMR spectra. The result of the analysis of the compounds was as follows.
