PROCESS FOR THE PREPARATION OF ISO-PHTHALONITRILE FROM ISO-PHTHALIC ACID |
| 摘要 |
The method manufactures the isophthalonitrile from reacting isophthalic acid and ammonia. The manufacturing method comprises: A) synthesizing meta-cyanobenzoic acid from a isophthalic acid of 150-500μ powder and ammonia at 350-450 deg.C; B) converting to isophthalonitrile by a catalyst of active alumina or silica in reactor of a fluidized bed type at 350-450 deg.C.
