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, 35857-89-7, name is 6-Chloropyridazine-3-carbonitrile, introducing its new discovery. Related Products of 35857-89-7
Compounds of the formula: STR1 where 2 THE R’s are the same or different and are H or CH3, and one of them can be C2 -C9 alkyl or phenyl; R1 is hydrogen, C1 -C4 alkyl, C3 -C6 cycloalkyl, C2l -C4 alkoxycarbonyl, or substituted C1 -C4 alkyl where the substituent is C3 -C6 cycloalkyl or phenyl; and Z is H, Cl or CH3 ; and their pharmaceutically suitable salts. The compounds are useful as sedatives; some of them also exhibit antidepressant activity.
Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Related Products of 35857-89-7
