| Abstract: | Objective： To establish a method for the determination of tetraethyl orthosilicate with cap- illary column gas chromatography. Methods： Selecting amyl acetate as an internal standard, using HP-5 cap- illary column gas chromatography with FID detector to determine tetraethyl orthosilieate. Results： A better linear relation was found between the peak area and the concentration of tetraethyl orthosilicate, r = O. 9999, the precision was well, the recovery was 99.1%- 101.2%. Conclusion： This method for the determination of tetraethyl orthosilicate was simple, accurate and rapid. |
