摘要
研究了在固体催化剂上乙缩醛气相分解制乙烯基乙醚的反应性能。结果表明,自制固体磷酸盐催化剂具有良好的活性和稳定性,在反应温度300°C、LHSV 1.0 h-1条件下稳定运行2000 h没有活性衰减,乙缩醛转化率和乙烯基乙醚收率分别约96.0%和91.0%,反应后催化剂表面沉积物量不足2.0%。
Vapor phase decomposition of acetal on solid phosphate was studied. It was found that the catalyst was highly active and stable for the decomposition of acetal. During the test run of 2000 h, the conversion of acetal and the yield of ethyl vinyl ether maintained about 96.0% and 91.0% ,respectively, at 300℃ and LHSV of 1.0 h^-1
