| titleOfInvention | Manufacturing Method of Leechihwan Urea |
| abstract | The present invention relates to a method for preparing N, N'-disubstituted urea represented by the following Chemical Formula 1 by reacting in the presence of an aromatic mononitro compound, an aromatic primary amine, carbon monoxide, a catalyst complex and a water adsorbent. compound is a nickel complex represented by the general formula NiX 2 (LL), wherein X is a halogen, NO 3, OCOCH 3, OCOCF 3, LL is by the formula Ph 2 P (CH 2) nPPh 2 as a bidentate ligand Wherein Ph is phenyl and n is an integer of 2 to 5, and a water adsorbent is used to provide a process for producing N, N'-disubstituted urea using zeolite, silica, alumina or magnesium sulfate. [Formula 1] [Ar in Formula 1 is an unsubstituted aromatic group; An aromatic group substituted with one or more substituents selected from halogen, alkyl having 1 to 4 carbon atoms, and alkoxy having 1 to 4 carbon atoms.] |
