Embodiment 1
[0058] Take the white insect wax raw material, pressurize it in the reaction tank at 110° C. and melt it; (2) add 20% NaOH solution of 1.5 times the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa and saponify for 6 hours; After the saponified product was washed with water, it was dried at 50°C to obtain the crude product; (4) put the crude product into a continuous extractor, and add No. 6 solvent oil for continuous extraction for 3 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, The concentrated solution was cooled to 20°C, and crystals were precipitated; the crystals were obtained by filtration; and the crystals were dried for 3 hours. After drying, the crystals are ball-milled into fine powder and passed through a 90-mesh sieve, and the dry matter is crushed, mixed and packaged.
Embodiment 2
[0060] Take the white insect wax raw material, pressurize it in the reaction tank at 100°C and melt it; (2) add 25% KOH solution of 1 times the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa and saponify for 5 hours; After the saponified product was washed with water, it was dried at 40°C to obtain the crude product; (4) put the crude product into a continuous extractor, add petroleum ether for continuous extraction for 2 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, and concentrate The liquid was cooled to 15°C, and crystals were precipitated; the crystals were obtained by filtration; the crystals were dried for 2 hours. After drying, the crystals are ball-milled into fine powder and passed through a 60-mesh sieve, and the dry matter is crushed, mixed and packaged.
Embodiment 3
[0062] Take the white insect wax raw material and melt it under pressure at 115°C in the reaction tank; (2) add 20% NaOH solution twice the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa for 7 hours for saponification; After the saponified product was washed with water, it was dried at 65°C to obtain the crude product; (4) put the crude product into a continuous extractor, and add No. 6 solvent oil for continuous extraction for 4 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, The concentrated solution was cooled to 45°C, and crystals were precipitated; the crystals were obtained by filtration; and the crystals were dried for 4 hours. After drying, the crystals are ball-milled into fine powder and passed through a 120-mesh sieve, and the dry matter is pulverized, mixed and packaged.
