DOI: 10.11777/j.issn1000-3304.2014.13412, PP. 948-955
Keywords: 聚丙烯腈,2,3-环氧丙基三甲基氯化铵,酯交换反应,碱性非均相催化剂
Abstract:
以聚丙烯腈纤维（PAN）为原料，氢化铝锂为还原剂，先将PAN上的腈基还原为伯胺基团得到还原产物PAN-NH2（APAN），再与具有季铵结构的2，3-环氧丙基三甲基氯化铵（EPTAC）键合，制备出季铵键合PAN聚合物；最后通过氢氧化钠活化得到具有强碱性季铵基团的聚合物PAN-N+（CH3）3OH-（QPAN）.考察了氢化铝锂、EPTAC加入量及反应时间、温度等因素对季铵基键合量（—N+（CH3）2Cl-含量）的影响规律，采用X-射线光电子能谱（XPS）、红外光谱（FTIR）、示差扫描量热仪（DSC）等对聚合物结构和性能进行表征.结果表明，当PAN与还原剂氢化铝锂摩尔比为13，温度为80℃，反应时间为24h时，伯胺基团含量可达到0.4812mmol/g.进一步用还原产物APAN与EPTAC以最优反应条件（摩尔比13，温度80℃，反应时间12h）下进行反应，所得产物通过NaOH活化，得到碱强度为0.8034mmol/g的QPAN.将QPAN用于大豆油和甲醇的酯交换反应制备生物柴油.在反应温度60℃，反应时间4h，醇油摩尔比为161，QPAN添加量为2.0meq（OH-）的条件下，生物柴油产率可达64.7%.
