In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 80636-30-2, name is 3,3-Dimethyl-3,4-dihydroquinoxalin-2(1H)-one, introducing its new discovery. category: quinoxaline
2-Keto-1,4-diazacycloalkanes
Novel polysubstituted 2-keto-1,4-diazacycloalkanes are powerful stabilizers for materials subject to ultraviolet (UV) light degradation, particularly for polyolefins. The cyclic 2-keto compounds of this invention have (a) a fixed two-carbon bridge between the N1 and N4 atoms of the diaza ring, the remaining portion of the ring having a variable length bridge of two or more carbon atoms, (b) an N-adjacent carbonyl in the fixed two-carbon bridge, and (c) at least one N4 -adjacent carbon atom of the diaza ring is polysubstituted, that is, has two substituents which may be cyclizable. Compositions containing (a) the polysubstituted 2-keto-1,4-diazacycloalkanes of this invention, and (b) prior art polysubstituted 2-keto-1,4-diazacycloalkanes, exhibit excellent stability to UV light.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 80636-30-2, and how the biochemistry of the body works.category: quinoxaline
