摘要
采用气相色谱法测定改性聚酯(PNT)中共聚组分新戊二醇(NPG)的含量,确定了色谱柱、柱温、进样量、分流比,制作了新戊二醇的定量曲线,摸索了共聚改性聚酯的醇解温度和醇解时间,得出了新戊二醇含量随共聚改性聚酯醇解温度和醇解时间的变化规律。
The article established a analysis of neopentylglycol with gas chromatography, packed with suitable column, column temperature, the content of injector, split ratio, made out the curve line of quanlitative analysis for neopentylglycol, selected the temperture and time of dissolving modified PET with methanol, and find out the change regular for the content of neopentylglycol with it.
