Research and Development of Eco-Friendly Rubber Oil by Extraction with Mixed Solvents
摘要
Abstract
Eco-friendly rubber oil was prepared from the Middle East medium distillates mixture by one-time extraction with mixed solvents to remove polycyclic aromatic hydrocarbons.This paper presented the comparative study on the extraction effects of solvents A,B,C and the mixed solvents of the three solvents.And the effect of solvents mixed ratio,the ratio of solvents and oil,extracting temperature,and extracting time on extraction were investigated,too.The results indicated that mixed solvents had better selectivity and solubility.With the solvents mixed ratio of m(C)/m(A)=1∶1 and extractant to oil ratio of 2∶1,extracting at 45 ℃ for 10 min,the polycyclic aromatics content in raffinate oil could be reduced from 5.74% to 2.78%,meeting the EU instruction 2005/69/EC requirements,and the yield of product reached 88.1%.All in all,the final product had similar qualities compared to VIVATEC 500.关键词
