The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.2103-99-3, Name is 4-(4-Chlorophenyl)thiazol-2-amine, molecular formula is C9H7ClN2S. In a Patent£¬once mentioned of 2103-99-3, Safety of 4-(4-Chlorophenyl)thiazol-2-amine
The invention relates to a process for the manufacture of 1:1 metal complexes of azines of the formula STR1 wherein R1 is a hydrogen atom, an alkyl or aryl group, R2 is an isocyclic or heterocyclic radical containing a hydroxyl or mercapto group adjacent to the azomethine group, Y is the radical of a compound which contains active methylene groups, or of an aryl or heteroaryl amine, and the ring A can contain substituents that do not confer solubility in water, which process comprises reacting a compound of the formula STR2 wherein R3 is a hydrogen atom or an alkyl radical, R4 is an alkyl, aryl or heteroaryl radical or the radical of the formula STR3 or R3 and R4, together with the nitrogen atom to which they are attached, form a 5- or 6-membered heterocyclic ring, and Y has the given meaning, with a hydrazone of the formula STR4 in the presence of a transition metal donor and in a polar organic solvent, at temperatures above 100 C. Compared with pigments obtained by the prior art methods, the pigments of this invention have greater purity and better fastness properties, especially better fastness to migration, overspraying, light, atmospheric influences and heat.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 4-(4-Chlorophenyl)thiazol-2-amine, you can also check out more blogs about2103-99-3
