At high relative humidity (RH), orthorhombic paracetamol (form II) crystallized from ethanol transforms to monoclinic (form I) faster than such crystallized from the melt. The present study attempts to elucidate the reasons for this difference in sta

Crystal structure (polymorphism) as well as crystal shape (morphology) and size have a huge practical and commercial impact on active substances all the way from research to manufacture of the final product. For an optimal development process, it is

The gas phase reaction of 2,2-dimethyl-1,3-propandiol over ion (alkali) exchanged zeolites gives 2-methyl-propanal (I) (cleavage product), 2-methyl-butanal (II) (rearrangement product) and traces of 3,3-dimethyl-oxetane (cyclisation). The selectiviti
