Abstract—

The paper reveals the thermodynamic and kinetic patterns of phase-forming vitrification. The conversion of a low-molecular-weight substance into a glassy state enables to increase the chemical activity of this substance with respect to its standard crystalline state without changing the reaction consuming this substance. An expression has been obtained to quantify this increase. To distinguish the reactivity of polymorphic modifications of a crystalline reagent, the following rule of fining activation has been substantiated: a reaction consuming a crystalline reagent should be carried out in region of its polymorphic transformation using exactly the modification that is more susceptible to domainization. The multiplicity of reaction acceleration due to the domainization of the reagent has been determined.
