糠醛抽出油制备橡胶软化剂的研究

采用溶剂抽提糠醛抽出油中的重质芳烃,用以生产橡胶软化剂,提高了抽出油的利用价值。结果表明,选用具有良好选择性的糠醛作为抽提剂,原料油在反应温度为60℃,m(溶剂):m(原料油)为2.0,抽提时间为3min,精制时间30min的条件下,抽出油可制取高分子芳烃类橡胶软化剂,其抽余油可作为催化裂化装置的原料,该工艺具有良好的应用前景。

Developing Rubber Softener From Furfural Extraction Oil

A method of solvent extraction to separate heavy aromatics was adopted from furfural extraction oil,which is used to produce rubber softener.This provides a good technique for taking good advantage of the extraction oil.The results show that with the furfural as the extract reagent,under the condition of the extract temperature is 60 ℃,the mass ratio of solvent to oil is 2.0,extract time 3 min,the sedimentation time is 30 min.After furfural extraction,the rubber softener satisfies the standard of rubber softener.A good macromolecule aromatics rubber softener would be obtained,and the remained oil can be used as the raw material of FCC.So this technology has good application potentials.
