摘要:
采用气相色谱在线外标定量分析丙酮催化缩合制备异佛尔酮的产物。将配制的丙酮催化缩合制备异佛尔酮产物的标准样品(或与惰性气体混合)由液体进料精密计量泵计量后加入未装催化剂的反应器中,测得各组分的质量分数与峰面积之间的关系,拟合出各组分的标准曲线。在相同的色谱分析条件下,将反应原料丙酮和惰性气体混合后加入反应器中,在线测得反应条件下各组分的峰面积。根据各组分的标准曲线,计算出各组分的质量分数及质量流量、丙酮的转化率及各产物的选择性。
Abstract:
Isophorone prepared from acetone by condensation,dehydration and cyclization was analyzed quantitatively by online chromatography method.The isophorone standard prepared from acetone liquid sample(or mixed with inert gas)was pumped into the reactor without catalyst by a precision metering pump for liquid feed metering.The relationship between the mass fraction of each component and the peak area was measured and fitted to the standard curve.Under the same chromatographic conditions,the reaction raw materials such as acetone mixed with inert gas were pumped into the reactor,and the peak area of each component under the reaction conditions was online measured.According to the standard curve for each component,the mass fraction and the mass flow of each component,the acetone conversion and the product selectivity were calculated.
