Embodiment 1
[0022] A total of 1000ml of DNW-II temperature-resistant resin catalyst produced by Dandong Mingzhu Special Resin Co., Ltd. was loaded into the reaction zone in the hydration reactor, cyclopentene was added to storage tank E, water was added to storage tank F, and water and cyclopentene were added. The molar ratio of pentene is 5, and the feed space rate of cyclopentene is 0.5h -1 , pump cyclopentene and water into intermediate tank C respectively, pre-mix with circulating material in intermediate tank, then inject water and reactor through pump, hydration reaction occurs through impact, and the amount of circulating material is feed amount 95% of. The reaction temperature is controlled to be 150°C, and the reaction pressure is 4.0MPa. The reaction product flowing out from the outlet of the reactor is separated to separate unreacted cyclopentene, and the remaining materials are analyzed by a 6890N gas chromatograph of Agilent Company. The conversion of pentene was 35.6%.
Embodiment 2
[0024] According to the method of embodiment 1, just cyclopentene feed space velocity is 2.0h -1 , The amount of recycled material is 75% of the feed amount. The reaction product flowing out from the outlet of the reactor was separated to separate unreacted cyclopentene, and the remaining materials were analyzed by 6890N gas chromatograph of Agilent Company, and the conversion rate of cyclopentene was measured to be 27.8%.
Embodiment 3
[0026] According to the method of embodiment 1, the cyclopentene feed space velocity is 3.0h -1 , the circulating material rate is 150% of the feed amount. The reaction product flowing out from the discharge port of the reactor was separated to separate unreacted cyclopentene, and the remaining materials were analyzed by 6890N gas chromatograph of Agilent Company, and the conversion rate of cyclopentene was measured to be 25.8%.
