Embodiment 1
[0058] Add 200 g of waste oil after dehydration (acid value 83.2KOH / g oil, golden color) into a 500ml closed high-pressure reactor, add 15% methanol whose quality is waste oil, acid catalyst (aluminum chloride: ferric chloride =80:20) The mass is 3% of waste oil, heated to 125°C, pressure 0.4MPa, stirred rapidly for half an hour, distilled excess methanol and water under normal pressure, took the supernatant to test the acid value of 29.52gKOH / g oil , add methanol 15% again, heat to 125°C, pressure 0.4MPa, carry out high-temperature esterification for 0.5 hours, distill off excess methanol and water under normal pressure, separate and remove the catalyst, and obtain the supernatant liquid as refined esterified oil with an acid value of 1.09gKOH / g oil;
[0059] The above-mentioned refined esterified oil product was added to a 500mL normal pressure reactor, 16% methanol, 1% KOH catalyst were added, and the reaction was stirred at 70°C for 1.5 hours, the reaction was stopped, exc...
Embodiment 2
[0067] Add 200 g of hogwash oil after dehydration (acid value 23.2KOH / g oil, yellow color) into a 500ml closed high-pressure reactor, add 15% isoamyl alcohol whose quality is hogwash oil, acid catalyst (aluminum chloride: chloride Iron=50:50) The mass is 3% of hogwash oil, heated to 145°C, pressure 0.4MPa, high-temperature esterification reaction for 0.5 hours, distilled excess isoamyl alcohol and water under normal pressure, separated and removed the catalyst, and obtained the supernatant It is a refined esterified oil with an acid value of 2.35gKOH / g oil;
[0068] The above-mentioned refined esterified oil product was added to a 500mL normal pressure reactor, 20% isoamyl alcohol, 1% KOH catalyst were added, stirred and reacted at 140°C for 1.5 hours, the reaction was stopped, excess isoamyl alcohol was distilled off, and crude glycerin was separated. Obtain crude fatty acid isopentyl ester;
[0069]The isoamyl ester of crude fatty acid mentioned above is intermittently rect...
Embodiment 3
[0076] Add 200g of acidified oil after dehydration (acid value 145.8KOH / g oil, dark brown in color) into a 500ml closed high-pressure reactor, add 20% ethanol whose quality is acidified oil, acid catalyst (aluminum chloride: ferric chloride =40:60) The mass is 3% of the acidified oil, heated to 135°C, pressure 0.5MPa, high-temperature esterification reaction for 0.5 hours, distilled excess ethanol and water at atmospheric pressure, and the acid value of the supernatant was 28.04gKOH / g oil, add 14% ethanol again, heat to 135°C, pressure 0.5MPa, carry out high-temperature esterification reaction for 0.5 hour, distill off excess ethanol and water under normal pressure, separate and remove the catalyst, and obtain the supernatant liquid as refined esterified oil, acid The value is 2.12gKOH / g oil;
[0077] Add the above-mentioned refined esterified oil product into a 500mL normal pressure reactor, add methanol 16% (based on the amount of refined esterified oil, the same below), KO...
