Undecylenic acid methyl ester (UAME) was continuously produced from methyl ricinoleate using a microwave-assisted pyrolysis system with atomization feeding. The UAME yield of 77 wt.% was obtained at 500°C using SiC as the microwave absorbent and heating medium. The methyl ricinoleate conversion and UAME yield from microwave-assisted pyrolysis process were higher than those from conventional pyrolysis. The effect of temperature on the pyrolysis process was also investigated. The methyl ricinoleate conversion increased but the cracking liquid yield decreased when the temperature increased from 460°C to 560°C. The maximum UAME yield was obtained at the temperature of 500°C.
十一烯酸甲酯（UAME）通过雾化进料的微波辅助热解系统，从甲基蓖麻醇酸酯连续生产。在 500°C 下，以碳化硅作为微波吸收剂和加热介质，可获得 77wt%的 UAME 产率。与传统热解相比，微波辅助热解过程中甲基蓖麻醇酸酯的转化率和 UAME 的产率更高。还研究了温度对热解过程的影响。当温度从 460°C 升高到 560°C 时，甲基蓖麻醇酸酯的转化率增加，但裂解液的产率下降。在 500°C 时，可获得最大的 UAME 产率。
