摘要: The crystallization process of n-hexatriacontane (n-C36H74) was investigated by means micro-FTIR spectroscopy. From the results in-situ oblique IR transmission measurements, it confirmed that single crystals M011 modification exhibited a polytypic transformation during solution growth. At initial stage crystallization, appeared as single-layered polytype (Mon). overgrowth double-layered (Orth II) took place subsequently on (001) face crystal. After that, crystal gradually transformed into Orth II type through solution-mediated phase transition. It suggested from Mon to caused drop in supersaturation solution.
