Kinetics of Ethylene Chlorohydrin Reactions with Hydroxyl 2449 lutions. Crystals, while well defined, were small. As has been indicated, the beta prime X-ray pattern is somewhat similar to that of subalpha. The distinguishing features are indicated in Table IV, a summary table of characteristic values. In brief, the chief difference is that beta prime lacks the two medium strength lines shown by subalpha for the region between 4.15 Á. and 3.65 Á.Beta.-The beta form is obtained by slow crystallization from solvent or by transformation of alpha and beta prime forms. It was not obtained directly from the melt. The crystals from solvent are relatively large platelets with a beautiful gloss. Beta is the only truly stable crystalline form.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
