Abstract
A kind of technology of separating and filtering mouth stub principal component, relate to the stub comprehensive utilization, comprise with ethanol subsequent leaching method cellulose diacetate and flue gas deposit are separated, and use peroxidating acetic acid, Huo bleaches purification to cellulose diacetate, the product of gained, the content of acetic acid is greater than 53% in the cellulose diacetate, and viscosity is 500 centipoises, meets spinning requirement, the mixture that contains nicotine and triacetyl glycerine can be made agricultural fungicides, and etoh solvent and acetone can recycle in technological process.
Description
Cigarette filter is made up of excellent core and coated papers that the cellulose diacetate bonding forms, contains binding agent triacetyl glycerine about 6% in the excellent core.After the smoking, also held back the deposit in the flue gases such as nicotine, spices, catechol, alditol, indenes and pyridine in cellulose diacetate rod core, wherein nicotine content is the highest, because of its content in tobacco leaf can reach 10%; Cellulose diacetate, its molecular formula is: C

3-X, X=2.28-2.49 are dissolved in acetone and are insoluble to ethanol, industrially make catalyst with sulfuric acid, with cotton fiber through the reaction of acetic anhydride vinegar and add the hydrolysis of water spirit of vinegar and make.Make 1 ton of cellulose diacetate, need to consume 98 kilograms in 701 kilograms of refined cotton linters, 2771 kilograms of acetic anhydride, 3668 kilograms of acetic acid and sulfuric acid, cost is comparatively expensive.But at present in the world, but have in the thousands of ton cigarette filters cellulose diacetates through once with after promptly discarded.If can adopt simple and easy method that principal components such as cellulose diacetate, triacetyl glycerine and nicotine are wherein recycled, not only save material, and on economizing on the use of funds, positive effect is being arranged all.
Purpose of the present invention is that an easy process route that separates cellulose diacetate and nicotine, triacetyl glycerine mixture that extracts from the filter tip stub will be provided.
The present invention is achieved in that
1. the recovery of cellulose diacetate
With the filter tip stub of collecting, peel through the coated papers of special equipment the stub appearance, emanate by wind-force, remove the coated papers chip, broken pipe tobacco and dust, utilize cellulose diacetate to be insoluble to ethanol and flue gas deposit and triacetyl glycerine are dissolved in the characteristic of ethanol, diacetate fiber rod with gained, by ethanol subsequent leaching device, cellulose diacetate and other composition are separated, then, the cellulose diacetate rod that will be full of ethanol moves in the bleacher, add the peroxidating acetic acid of 3-5%, bleach, again vacuum draw, oven dry, remove ethanol, and place pressure cooker to add the acetone solution cellulose diacetate, through decolorizing with activated carbon, purify (harmful substance that absorption may be residual), remove activated carbon, boil off acetone, promptly get and to be made for spinning, again the cellulose diacetate of filter made mouth raw material.
2. the recovery of triacetyl glycerine and flue gas deposit
With the ethanol leaching liquid in the above-mentioned technology, add the ethanol of bleaching with recovery, make aminate chemical combination salifies such as the interior nicotine of contained free acetic acid and leaching ethanol, pyridine, in water-bath, steam ethanol, and send into technical process again and reuse advancing cold the pinching of condenser after making alcohol vapour by an activated carbon layer; Residue obtained principal component is nicotine and triacetyl glycerine.
The technology of separating and filtering mouth stub principal component of the present invention, yield can reach about 40%, relatively gentleer because of handling, degraded does not take place and take off the reaction of second vinegar, agents useful for same ethanol, acetone use for capable of circulation time, loss is few, products therefrom is by B.S2880(MethOds of Testing cellulose acetate flake.) detect, in conjunction with acetic acid more than 53%, about 500 centipoises of viscosity meet the spinning quality requirement.In addition, in processing procedure, through the ethanol lixiviate, operations such as peroxidating acetic acid bleaching and disinfecting and activated carbon decolorizing, purification make the gained cellulose diacetate, still can be used as to make filter-tip raw material, and greatly reduce cost.
Following examples will help further understanding of the present invention:
Embodiment: get 150 at filter tip stub, screen out dust, cut coated papers with blade, blow down paper scrap and broken pipe tobacco with fan, gram surplus the diacetate fiber rod 20, wrap up with absorbent gauze, the extraction column of the Soxhlet of packing into device (Soxhlet extracttion) adds 50 milliliters of 95% industrial alcohols, insert condenser and cucurbit, add 200 milliliters of 95% industrial alcohols in the cucurbit, reflux on water-bath is leached, and observes the color of ethanol in the overflow pipe, by deep yellow become colourless till, about 2-3 of time hour, take out the cellulose diacetate rod that is full of ethanol and place in the closed container, add the bleaching of 3-5 milliliter peroxidating acetic acid, normal temperature was placed 24 hours, place the Buchner funnel suction filtration, absorb ethanol, air drying, move in 500 milliliters of distilling flasks, add 228 milliliters in acetone (180 gram), vibrated 15 minutes, placed 24 hours, be chilled to normal temperature, through the Buchner funnel suction filtration, in impouring 1,000 ml distilled waters, get thread cellulose diacetate slowly, be placed on and absorb moisture in the Buchner funnel, B.S2880.4 maneuver detection press in oven dry in about 100 ℃ in baking oven, according to the content of following formula calculations incorporated acetic acid:
Chemical combination acetic acid=(3.002X(A-B))/(W) * 100
W-sample weight (gram)
A-0.500N NaOH(sample titration consumption) (milliliter)
B-0.500N NaOH(blank titration consumption) (milliliter)
By the cellulose diacetate that this law is obtained through refining, the chemical combination acetic acid content is greater than 53%.
Press the B.S2880.8.d maneuver, measure viscosity with homemade rotation viscometer (Tongji University supervises), cellulose diacetate 25% concentration of obtaining through refining by this law, and under 25 ℃, viscosity is greater than 500 centipoises.
