DEFINITION

Classification: 44/272

With organic -C(=X)X- compound, wherein the X's are the same or diverse chalcogens (e.g., aluminum carboxylates, rosin salts, etc.):

(under subclass 268) Compositions wherein the solidified liquid fuel composition contains as a component an organic-C(=X)X- compound, wherein the X's are the same or diverse chalcogens (i.e., oxygen, sulfur, selenium, or tellurium).

(1) Note. The organic -C(=X)X- compound is usually, but not always, present as a binder.

(2) Note. An organic -C(=X)X- compound is one in which the carbon of the -C(=X)X- group is, or is attached directly or indirectly by nonionic bonding to, the carbon of an organic compound.

(3) Note. See (4) Note of the class definition for the definition of "organic compound".

(4) Note. Rosin, the principal substituent of which is abietic acid, is also known as colophony.
