摘要:
研究了工业季戊四醇水溶液的介稳区性质,测定了工业季戊四醇在水溶液中的溶解度和过饱和度,获得了工业季戊四醇的介稳区宽度;同时研究了降温速度、搅拌速度对工业季戊四醇介稳区宽度的影响,并推算出工业季戊四醇的成核级数.实验结果表明:在水溶液中,工业季戊四醇的溶解度随温度的升高而逐渐增大;且温度越低,所对应的介稳区宽度越宽;受最大过饱和度和搅拌速度影响的成核级数与饱和温度几乎均没有关系,成核级数分别为2.36和0.26.
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.
