Class Information
Number: 554/174
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 > Esterification of fatty material to reduce the amount of free fatty acid or to facilitate separation of constituents
Description: Processes wherein the hydrogen of a -C(=O)OH group of a free fatty acid is replaced by a carbon atom, which carbon may be single bonded to any atom but multiple bonded only to carbon, to reduce the free fatty acid content of the fatty compound source material or to facilitate separation of the constituents of the mixture.
