20160115114 | Device and process for producing undecylenic acid methyl ester using methyl ricinoleate as raw material - A device and a process for producing undecylenic acid methyl ester using methyl ricinoleate as raw material are provided. The device comprises a feed pump, a raw material pre-heater, a microwave catalytic reactor, a microwave generator, a temperature controller and an infrared sensor, a condenser, a product tank and a discharge pump. The feed pump is connected with the raw material pre-heater, which is connected with the inlet of the microwave catalytic reactor. The outlet of the microwave catalytic reactor is connected with the condenser, which is connected to the product tank and the discharge pump. The microwave catalytic reactor is located in the microwave generator, which is connected with the temperature controller and the infrared sensor. The process is as follows: high-purity methyl ricinoleate, used as the raw material, is converted to methyl undecene and heptaldehyde by microwave-assisted pyrolysis process, followed by isolation and purification to produce methyl undecene. | 04-28-2016 |
