标题 :Purification of copper contaminated dye compounds using di(hydroxyalkyl)sulfides
发明人：GILES R; STRALEY J
权利人:EASTMAN KODAK CO
摘要:COPPER IMPURITIES IN DYE COMPOUNDS ARE REMOVED BY CONTACTING SUCH A CONTAMINATED COMPOUND WITH A DI(HYDROXYALKYL)SULFIDE AND RECOVERING THE DYE SUBSTANTIALLY FREE OF COPPER. THE PROCESS CAN BE EMPLOYED IN CONJUNCTION WITH THE SYNTHESIS OF CAYNO SUBSTITUTED DYES BY CYAMIDE DISPLACEMENT REACTIONS WHICH EMPLOY COPPER AS A CATALYST. THE PURIFICATION PROCESS RESULTS IN CERTAIN ADDITION COMPOUNDS OF A CUPROUS OF CUPRIC SALT AND THE DI(HYDROXYALKYL)SULFIDE.
