摘要
以四乙烯五肢为起始剂,按不同头尾比例合成PO-EO-PO型三段聚醚,并用瓶试法考察对石油破乳的效果及其复配作用。采用水数法测定HLB值,方法简单,结果可靠。
Synthesis of PO(b)-EO(b)-POb)-polyether from tetraethylenepentamine wIth different head-to-tail ratio is presented.The efect of demulsification on petroleum and combnation were tested by means of bottle method.The HLB values of the surface actlve agent was determined with a water number method, whlch is simple and reliable.
