A quantitative two-step analysis method was established to determine the main products of the vinyl acetate gas phase synthesis from acetylene method, such as acetic acid, acetaldehyde, acetone, vinyl acetate, and crotonic aldehyde, by gas chromatography with butyl acetate as internal standard. The experimental results show that components could be completely separated and has good linear relationships between the mass ratio and peak area ratio. The relative standard deviations are no more than 2.85%, and the average recoveries are from 94.60% to 104.059%.
