Dab tsi yog theem hloov catalyst?

 

Theem Hloov catalyst (PTC) yog hom catalyst uas tuaj yeem pab hloov cov reactants ntawm ib theem mus rau lwm theem uas tuaj yeem ua rau muaj kev tawm tsam heterogeneous. Feem ntau, nyob rau hauv cov tshuaj tiv thaiv nrog theem hloov catalysis, muaj ob theem: aqueous kev daws teeb meem thiab cov kuab tshuaj organic. Ionic reactants feem ntau soluble hauv dej theem, tab sis tsis nyob hauv cov organic theem, thaum organic substrates yog soluble kuab. Thaum tsis muaj theem hloov catalyst, these reactants tsis tuaj yeem hloov pauv cov organic rau cov agerous) thiab feem ntau yog kis rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov organic rau cov agerous
