| titleOfInvention | Separation method and isocyanate production method |
| abstract | The object of the present invention is to separate a mixture containing a plurality of compounds which react reversibly, in particular to a method for efficiently separating isocyanates from a mixture comprising isocyanate and hydroxy compound, in particular N-substituted carbamic acid esters. It is an object of the present invention to provide a method for efficiently separating an isocyanate and a hydroxy compound produced by thermal decomposition of the above. A method for separating a mixture containing an active hydrogen-containing compound (A) and a compound (B) that reacts reversibly with the active hydrogen-containing compound by a multistage distillation column, the standard of the active hydrogen-containing compound (A) Presence of intermediate boiling point inactive compound (C) having a normal boiling point between the boiling point and the normal boiling point of compound (B) and being chemically inert to both (A) and compound (B) The above problem is solved by a separation method in which the active hydrogen-containing compound (A) and the compound (B) are separated by distillation using the multistage distillation column. |
