响应面法优化醇溶性丙烯酸酯合成工艺
|
摘要
以乙醇为溶剂,甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、丙烯酸羟乙酯(HEA)和丙烯酸(AA)为单体,过氧化苯甲酰(BPO)为引发剂,合成了醇溶性丙烯酸酯。用Design Expert 10.1软件中的Box-Behnken Design(BBD)响应面分析法研究了聚合温度,引发剂和溶剂的质量分数(均按占单体总质量的百分数计),以及它们之间的相互作用对单体转化率的影响,确定了聚合物合成的参数组合,并建立了多元回归模型。结果表明,模型拟合良好,聚合温度与引发剂质量分数之间的相互作用影响最大,引发剂质量分数与溶剂质量分数的相互作用对单体转化率的影响最小。合成理论单体转化率为83%的醇溶性丙烯酸酯最优工艺条件为:引发剂质量分数0.84%,溶剂质量分数60%,聚合温度76°C。
An alcohol-soluble acrylate was synthesized using methyl methacrylate(MMA), butyl acrylate(BA),hydroxyethyl acrylate(HEA), and acrylic acid(AA) as monomers, ethanol as solvent, and benzoyl peroxide(BPO) as initiator.The effects of polymerization temperature, mass fractions of initiator and solvent(with respect to the total mass of monomers),and their interactions on the monomer conversion were studied by Box-Behnken Design(BBD) in Design Expert 10.1 software. The conditions of polymerization were determined and a multiple regression model was established. The results showed that the model fitted well. The interaction between polymerization temperature and initiator dosage was the strongest,while the interaction between solvent dosage and initiator dosage was the weakest. The optimal process conditions for achieving a theoretical conversion rate of 83% are as follows: initiator 0.84 wt.%, solvent 60 wt.%, and polymerization temperature 76 °C.
