DEFINITION

Classification: 526/227

(under subclass 89) Subject matter the specified material contains a compound having at least one -O-O- group.

(1) Note. Processes wherein a known peroxide is formed in situ by the reaction of a peroxide and another compound are classified on the basis of the peroxide that is utilized to form the in situ peroxide and cross-reference to the in situ formed peroxide.

90+, for a transition metal compound admixed with a peroxide compound or for a compound containing a transition metal and an -O-O- group therein.

184, for an organometallic compound admixed with a peroxy compound.

197, for a boron compound other than a boron trihalide or nonmetallic organic complex, per se, admixed with a peroxy compound.

223, for an organosulfur compound containing an -O-O- group therein.
