Abstract The physical properties of large single crystals of long chainn-paraffins and ketones would be of interest because of their structural similarity to polyethylene, but simple techniques for growing crystals from solution or the melt yield only small crystals. We have constructed a crystal growing apparatus using the predictions of Jackson's theory of growth morphology as a guide and, with high purity samples of C23H48 and C9H19COC9H19, have grown crystals with centimetre dimensions. The morphologies of the crystals are strikingly different. The hexagonal-orthorhombic phase transition in the paraffin produces a crystal with variable residual strain. The ketone has no phase transition and yields strain free crystals crossed by narrow strained regions.
