3. Chemical applications

NMRI has rarely been applied to everyday chemistry and chemical engineering. Simple chemical reactions in solution are generally considered to be spatially homogeneous, but can become heterogeneous on larger scales due to non-uniformities in temperature and reactant or catalyst concentration. Spatial reaction irregularities pose a problem for heterogeneous catalysis and polymerization reactions, during which rapid viscosity increases can "freeze" heterogeneities.

Several researchers have studied polymerization reactions , including Jackson, who worked on a carbon fiber-reinforced epoxy resin . By raising the temperature above 55°C to increase T ₂ , the unvulcanized...
