✦ Synopsis

Abstract

A new polymorph of sodium chondroitin‐4‐sulfate has been crystallized from an ethanolic aqueous solution at low pH. The crystallized spherulite specimens give considerably sharper x‐ray diffraction lines. The unit cell of the new polymorph is rectangular with dimensions (Å) a = 16.0, b = 24.1, and c = 26.0. The chondroitin‐4‐sulfate could be purified by recrystallization.

The bulk crystallization of a-lactose monohydrate from aqueous solution by primary nucleation has been studied under controlled conditions of supersaturation, temperature, and pH. The induction times to nucleation were extremely long compared with those generally observed for other materials, even a
