Abstract

Crystals are derived from a solution of a crystallizable compound by a thermal circulation system comprising upper and lower chambers, one chamber being under vacuum, the other under conditions other than vacuum. Heat is provided to promote vaporization of the solution and circulation of the liquid. Fresh solution of the compound to be crystallized is selectively supplied to one or both chambers. [US3859052A]
