【摘要】 甲醛是一种重要的化学中间体,多聚甲醛可作为甲醛替代品使用,一般须对其进行解聚。论文对多聚甲醛解聚进行了实验研究,直接热解聚和在溶剂中热解聚效果不理想;在溶剂中碱催化解聚效果较好,解聚温度80℃,pH=9~11,溶剂以异丙醇为宜。更多还原

【Abstract】 As a substitute of formaldehyde,paraformaldehyde should be depolymerized for better use.In this paper,the depolymerizaton of paraformaldehyde was studied.The experimental results show that thermal depolymerization is not satisfactory.Paraformaldehyde is depolymerized well in isopropyl alcohol at 80℃,pH 9~11.更多还原
