DEFINITION

Classification: 524/282

C(C=X)X wherein at least one X is a chalcogen other than oxygen DNRM:

(under subclass 81) Subject matter wherein the organic designated nonreactant material contains at least one C--X group, wherein X is a chalcogen atom (i.e., oxygen, sulfur, selenium, or tellurium), and wherein at least one of the X atoms is other than oxygen, e.g., n-butyl dithlofumarate, etc.
