Process for extract-separation of aromatic hydrocarbons |
| abstract |
A PROCESS FOR EXTRACT-SEPARATING AROMATIC HYDROCARBONS HAVING LARGER BASICITY INTO A HYDROGEN FLUORIDE PHASE BY ALLOWING AN EXTRACTING AGENT CONSISTING OF HYDROGEN FLUORIDE AND BORON TRIFLUORIDE TO COME IN CONTACT WITH A MIXTURE CONTAINING TWO OR MORE AROMATIC HYDROCARBONS HAVING DIFFERENT BASICITY FROM EACH OTHER. MORE PARTICULARLY, A PROCES FOR EXTRACT-SEPARATING AROMATIC HYDROCARBONS IN A HIGH YIELD AND PURITY WITHOUT SUBSTANTIALLY REFLUXING SAID AROMATIC HYROCARBON HAVING LARGER BASICITY, HERETOFORE CONSIDERED A NECESSITY, BY FEEDING EXTRACTING AGENT CONSISTING OF HF AND BF3, AND DILUENT IN HIGHLY PRECISE AMOUNTS ACCORDING TO A PREDETERMINED CORRELATION. |
