摘要:不溶性硫磺在热条件下易转化为普通硫磺,为考察各因素对测定不溶性硫磺在120℃下热稳定性的影响,进行了4因素4水平的正交试验,并对测定结果进行极差与方差法分析,得到了各因素对不溶性硫磺热稳定性影响的主次顺序和显著性,优化了测定条件。结果表明,各因素对测定结果的影响程度顺序依次为:恒温搅拌器转速、液体石蜡体积、搅拌时加入的二硫化碳体积、冷却时间。测定的优化条件为:液体石蜡体积为50 m L,搅拌时加入的二硫化碳体积为60 m L,磁力搅拌器转速为400 r/min,冷却时间为3 min。
The thermal stability of insoluble sulfur is an important property because the insoluble sulfur in hot conditions is easily converted into ordinary sulfur. A 4 factors 4 levels orthogonal experiment is designed to study the impact of various factors on the determination of the thermal stability of insoluble sulfur at 120℃. Through the range analysis and variance analysis,the orders and significance of the influencing factors on the thermal stability of insoluble sulfur are obtained. The influencing significance is shown in a descending manner: stirring speed of constant temperature stirrer,the volume of liquid paraffin,the volume of carbon disulfide and cooling time. The optimal conditions are determined as follows: 50 m L of liquid paraffin,60 m L of carbon disulfide,400 r / min of stirring speed and 3 minutes of cooling time.
