ecletica-190	Mortaheb, Hamid Reza; Mafi, Morteza; Mokhtarani, Babak; Khosravi, Kianoush; Mashkini, Fateme	Optimization of NMP extraction in 1,3-butadiene production line	2010	3	.pdf	application/pdf	2123	105	63	Optimization of the extraction by increasing solvent residue ratio Once the optimum temperature was determined, it was necessary to determine the effect of sol- vent residue ratio on the efficiency of the extraction. The impurities in S70°c phase is 0.75 weight percent whereas the NMP in the sample S70°c and S′ 70°c are similar in amount to the residue.	cache/ecletica-190.pdf	txt/ecletica-190.txt
