Embodiment 1
[0029] Example 1 Extraction of aroma components from cigarette butt tar
[0030] A method for extracting aroma components in cigarette butt tar, the method comprising the following steps:
[0031] (1) pretreatment of cigarette butts: tear off the outer wrapping paper of discarded cigarette butts, and cut the tow into small sections less than 1 cm long;
[0032] (2) put 100g of pretreated cigarette butts into 1000ml of dehydrated ethanol for 3h water-bath reflux extraction, the temperature of water-bath reflux extraction is 60°C, and then centrifuge at 1000r / min for 2min to obtain an extract;
[0033] (3) Filter the extract through a 10KD ultrafiltration membrane, control the pressure of ultrafiltration membrane filtration to be 1.0MPa, and the membrane flux to be 30L / m 2 ·h -1 , the temperature is room temperature, and the dialysate is obtained, and the dialysate is distilled and concentrated under reduced pressure at a temperature of 45° C. and a vacuum pressure of 1.0 mmH...

[0051] Example 2 Application of aroma components in cigarette butt tar into cigarettes
[0052] The aroma components in the tar prepared in Example 1 were added to the tow of low-end cigarettes at a ratio of 2% by mass of shredded cigarettes to prepare cigarette sample A.
[0053] The aroma components in the tar prepared in Example 1 were added to the tow of the mid-end cigarette at a ratio of 3% by mass of the shredded cigarette, to prepare a cigarette sample B.
[0054] The aroma components in the tar prepared in Example 1 were added to the lower-grade tobacco leaves of the low-end cigarettes at a ratio of 5% by mass of the shredded cigarettes to prepare a cigarette sample C.
[0055] The cigarette samples prepared by the above scheme and the cigarettes without adding aroma components in tar were equilibrated for 24 hours under the constant temperature and humidity environment of (20±1)℃ and relative humidity of (60±3)%, and then 10 or more people evaluated the samples. S...
Embodiment 3
[0059] Example 3 Selection of preparation method conditions
[0060] 1. The choice of organic solvent
[0061] Methanol, dichloromethane, anhydrous ethanol, glycerin, petroleum ether, and polyethylene glycol 400 were used to extract the pretreated waste cigarette butts for 2 hours, and the dosage ratio of waste cigarette butts to organic solvent was 1:10 (g / mL), The effects of different solvents on the extraction effect (the content of components extracted from each g of cigarette butts) were compared and analyzed, and the test results are shown in Table 2. It can be seen from Table 2 that the extraction effect using absolute ethanol is the best.
[0062] The extraction effect of table 2 different organic solvents (mg / g)
[0063]
[0064] 2. Selection of extraction temperature
[0065] 100g of pretreated waste cigarette butts were added to 1L of absolute ethanol, and extracted at 45°C, 60°C, 75°C, and 90°C for 2 hours, and each was extracted once. The effects of differ...
