摘要
Abstract
The meta-stable zone characteristics of industrial pentaerythritol solution were investigated, the solubility and the super-saturation of industrial pentaerythritol in aqueous solution were measured, and then the meta-stable zone width was determined. In addition, the effects of stirring rate and cooling rate on the meta-stable zone width were studied in aqueous solution, and the nucleation progression of industrial pentaerythritol was estimated. Experimental results showed that increasing the temperature, the solubility of industrial pentaerythritol in aqueous solution increased gradually. The lower the temperature, the wider of the meta-stable zone width was. The nucleation progression, which were affected by the maximum super-saturation and stirring rate, had no relationship with saturation temperature, and they were 2. 36 and 0. 26 respectively.关键词
