Embodiment 1
[0022] 1. Preparation and refining of sorbifolia seed oil
[0023] a. Picking Xantho sorbifolium fruit
[0024] The ripe sorbifolium fruit is picked in the first ten days of August every year, dried in the air, peeled off, impurities removed, and the seeds are air-dried.
[0025] b. Squeeze oil from Xantho sorbifolium seeds
[0026] Get 100Kg of sorbifolia seed, remove the seed coat to obtain 51Kg seed kernel, put the seed kernel into a hydraulic oil press and press continuously to obtain 26Kg sorbifolia crude oil. In order to improve the oil yield, the pressed cake was leached with 6# solvent to get oil, and a total of 32Kg of Xantho sorbifolium crude oil was obtained.
[0027] c. Refined
[0028] The sorbifolia crude oil was precipitated, filtered, degummed, and dried to obtain the radix sorbifolium seed oil.
[0029] 2. Transesterification to produce biodiesel
[0030] Take 1000 g of refined sorbifolia seed oil, 100 g of methanol, 20 g of 60-mesh solid acid catalyst la...
Embodiment 2
[0034] 1, the preparation and refining of sorbifolium sorbifolium seed oil are the same as embodiment 1.
[0035] 2. Transesterification reaction
[0036] Take 1000 g of refined sorbifolia seed oil, 204 g of methanol, 20 g of 60-mesh solid acid catalyst lanthanum trifluoromethanesulfonate, and 200 g of co-solvent 3-methylfuran.
[0037] Mix methanol and 3-methylfuran and add it to a 2L three-necked flask, preheat it to 40°C, add sorbifolia seed oil and lanthanum trifluoromethanesulfonate at the same time, heat up with stirring, and keep the temperature at 90°C ℃ for 30 minutes. Stirring was stopped and the lanthanum trifluoromethanesulfonate separated. The reaction solution was centrifuged at 2500 rpm, the supernatant was collected, heated to 80° C., and methanol and 3-methylfuran were distilled off to obtain 978 g of clear and transparent biodiesel with a yield of 97.8%.
[0038] Methanol and 3-methylfuran were distilled from the lower layer under normal pressure for recyc...
Embodiment 3
[0040] Take 1000 g of refined sorbifolia seed oil, 204 g of methanol, 20 g of lutetium trifluoromethanesulfonate catalyst of 60 mesh solid acid, and 90 g of co-solvent tetrahydrofuran.
[0041] After mixing methanol and tetrahydrofuran, add it to a 2L three-necked flask, preheat it to 40°C, add sorbifolia seed oil and lutetium trifluoromethanesulfonate at the same time, heat up with stirring, and keep the temperature at 80°C, and react 30min. Stirring was stopped and the lutetium triflate was separated. The reaction solution was centrifuged at 2500 rpm, the supernatant was collected, heated to 80° C., methanol and tetrahydrofuran were distilled off for recycling to obtain 963 g of clear and transparent biodiesel with a yield of 96.3%.
[0042] The lower layer was distilled under normal pressure to distill methanol and tetrahydrofuran for recycling, and then distilled under reduced pressure at 120°C and vacuum degree -0.1MPa to obtain glycerol as a by-product.
