| titleOfInvention | Process for the preparation of amino or hydroxybenzonitriles |
| abstract | claimednis a process for the preparation of amino or hydroxybenzonitriles,nin the case of ammonolysis, the corresponding amino ornHydroxybenzoic connectionsnwith ammonia in the presence of a phosphate-containing supported catalystnat temperatures between 250 ° Cnand 500 ° Cnbe implemented. The actual manufacturing step is in onenReaction gas (mixture) and without involvement of an organic solventncarried out,nfollowed by at least a 2-stage purification step. It willnfirstnthe gaseous mixture obtained from the production step into an aqueous,nconverted basic suspension andnsubsequentlynfrom this suspension released the product contained in the solid.nThe main advantage of this combination process is to be seen innthat it is not assumed that esters, which are the products obtainednunlike the usual onesnProcedure free from the usualnBy-products are what results in high product purity. Thenclaimed method can also be carried out in a very economical manner,nsince the final product and the by-products in the suspension usednexist in different states of aggregation and thereforencan be easily separated from each other. In this way you get solvent-freenAmino- or hydroxy-containing benzonitriles in high yieldnand significantly improved product quality. |
