| Abstract: | The gas chromatographic method for quantitative determining the 1, 4-butandiol which is present in liquid phasein the synthesis of bishydroxybutyl terephthaIate by direct esterification process has been investigated. Instead of thetradional tedious derivation procedure, a simp1e and convenient pretreatment process is used and results in separation of1, 4-butandiol and high boiling components , then 1, 4-butandiol is determined by internal standard methods. Theprecision and recovery of method are satisfactory and can meet the requirements of technology. |
