摘要
BHT结晶是以乙醇为溶剂,对不同浓度的乙醇,改变溶质与溶剂的物料配比,测定了BHT溶液的出晶点温度,结果表明,在乙醇浓度一定的条件下,出晶点温度随BHT与乙醇配比的增大而降低;而在相同物料配比的条件下,乙醇浓度越低,出晶点温度越高。
The crystallization process of BHT belongs to the cooling solution crystallization processes, which uses ethanol as the solvent. In this thesis, the crystallization temperatures of BHT under different concentrations of ethanol and different feed ratios of solute to solvent were measured. It is shown that the crystallization temperature increases with reduce of the feed ratio or the ethanol concentration.
