Class Information
Number: 554/186
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Fatty compounds having an acid moiety which contains the carbonyl of a carboxylic acid, salt, ester, or amide group bonded directly to one end of an acyclic chain of at least seven (7) uninterrupted carbons, wherein any additional carbonyl in the acid moiety is (1) part of an aldehyde or ketone group, (2) bonded directly to a noncarbon atom which is between the additional carbonyl and the chain, or (3) attached indirectly to the chain via ionic bonding > Purification, recovery, deodorizing, decolorizing or color stabilizing > Nitrogen containing compound treating agent > The treating agent is organic > Urea or nitro group containing
Description: Processes wherein the organic nitrogen containing treating agent contains a urea (i.e., --) or nitro (i.e., -NO2
