Abstract
The invention relates to a preparation method of a pomelo peel oil absorption material, which comprises the following steps of: (1) drying the pomelo peel in the air, cleaning with deionized water to remove impurities and dust on the surface, and drying in an air-blowing drying oven at 60-70 DEG C; (2) removing the yellow peel, making into 1-2cm square pieces, and drying in the air-blowing drying oven at 60-70 DEG C to constant weight for later use; (3) putting 1g of pomelo peel for later use into a round-bottom flask with 150ml of n-hexane; adding 0.5g of oleic acid, and dropwise adding one drop of concentrated sulfuric acid; and performing reflux in a water bath kettle at 65+/-2 DEG C for 6 hours; and (4) after 6 hours of reaction, filtering with a stainless steel filter screen, and then flushing with n-hexane; and putting the product into a watch glass and drying at 60-70 DEG C to constant weight. The preparation method of a pomelo peel oil absorption material, provided by the invention, has low cost, is simple to operate and is environment-friendly and pollution-free; and compared with the oil absorption material prepared from other raw materials, the obtained oil absorption material has the characteristics of waste recycling, fast oil absorption, large oil absorption multiple and the like.
Description
Technical field
The present invention relates to a kind of preparation method of shaddock skin oil absorption material.
Background technology
The leakage of various oils in use, transportation, serious environment pollution, especially huge to the negative impact of water bodys such as ocean, river, some oils such as crude oil, lubricating oil is biodegradable poor ability in physical environment, residence time is long, can havoc ecotope and the eubiosis.Handle all kinds of oil pollution accidents of water body, the most frequently used method is oil absorption material.
At present, common oil absorption material has two big classes, and a class is the oil absorption material of chemosynthesis, and as polypropylene or urethane, they have excellent hydrophobic property and lipophilicity, but its utmost point difficult for biological degradation, and expensive.Another kind of is natural oil absorption material, and natural inorganic oil absorption material as vermiculite, diatomite etc., because its oil absorbency is low, also absorbs water in the time of oil suction, seldom uses; Natural organic oil absorption material, as porous materials such as raw cotton, agricultural crop straw, lumber fibres, oil absorbency is better, if but handle without modification, also absorb water in the time of oil suction, so the study on the modification of natural organic oil absorption material becomes focus.
It is the high oil absorption composite material of the cellulose waste filler of raw material reaction preparation that CN101550261A discloses with acrylate copolymer high oil absorbing resin and cellulose castoff (bagasse, corn cob, Pericarppium arachidis hypogaeae and sawdust powder).CN101654247A discloses with the shaddock leather and has been equipped with process of active carbon.It is the preparation method of the oil absorption material of base material that CN102344531A discloses with stalk (maize straw, wheat stalk, broomcorn straw etc.).It is the degradable oil absorption material of raw material reaction preparation that CN1417263A discloses with bagasse and aceticanhydride.
Grapefruit is as a kind of evergreen undershrub, and fruit is delicious, has pharmaceutical use and the output value is huge, and domestic annual production is greatly about about 2,000 ten thousand tons.If pericarp is not used and namely causes wasting of resources contaminate environment again.Therefore, manage to utilize this kind of plant pericarp as the raw material of preparation oil absorption material, it is turned waste into wealth, significant.Because the shaddock leatherware has many crisscross passages, so itself just has the characteristic of porous, be the good raw material of preparation oil absorption material, starting material are environmentally friendly thus, do not produce environmental pollution.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of shaddock skin oil absorption material.
For achieving the above object, the present invention adopts following technical scheme:
A kind of preparation method of shaddock skin oil absorption material is characterized in that the concrete steps of this method are:
A. with after shaddock skin cleaning, the air-dry drying, remove the yellow appearance skin, make the square of 1 ~ 2cm, it is stand-by to be dried to constant weight again;
B. step a gained shaddock skin is immersed in the normal hexane, adds oleic acid, and drip the vitriol oil of catalyst levels, in 60～65 ℃, refluxed 5～7 hours; After filtration, after the normal hexane flushing, be dried to constant weight, namely get oil absorption material.
This method is not only simple to operate, the reaction conditions gentleness, and also used raw material is the shaddock skin, its wide material sources, inexpensive, and comprehensive cost is lower, and oil absorptiveness is good; The biological degradation of shaddock micromicro, environmental friendliness
Description of drawings
Fig. 1 prepares the absorption multiplying power of shaddock skin in different media.
Embodiment
Embodiment one:
(1) after the shaddock skin is air-dry, with deionized water clean surface foreign material and dust, 60 ~ 70 ℃ of dryings in air dry oven;
(2) remove the yellow appearance skin, make the square of 1 ~ 2cm, it is stand-by to be dried to constant weight again in 60 ~ 70 ℃ of convection oven;
(3) stand-by 1g shaddock skin is put into the round-bottomed flask that the 150ml normal hexane is housed, add 0.5g oleic acid, and drip 1 vitriol oil, 6h refluxes in 2 ° of C water-baths of 65 scholars;
(4) behind the reaction 6h, filter with stainless steel filtering net, again with the normal hexane flushing, be dried to constant weight under 60 ~ 70 ℃ behind the watch-glass of packing into afterwards.
Product absorption multiplying power such as Fig. 1 (UMPP represents the natural pomelo skin, and OAPP represents the shaddock skin of oleic acid modification, and hollow type and solid type represent diesel oil and lubricating oil respectively) in different media.
Beneficial effect
(1) preparation method of shaddock skin oil absorption material of the present invention is to be raw material with the shaddock skin, by the method for oleic acid modification, and preparation shaddock skin oil absorption material.Compare with traditional resin matrix preparation method because the tiny internal structure of shaddock skin, make product oil absorptiveness be improved significantly.
(2) preparation method of shaddock skin oil absorption material of the present invention because the shaddock skin itself has good degradability, can eliminate discarded synthetic materials to the pollution of environment, maintaining ecological balance.
(3) preparation method of shaddock skin oil absorption material of the present invention, raw material sources are extensive, and reaction reagent is easy to get and is cheap, and reaction process is simple, and comprehensive production cost reduces significantly.But have refuse resource utilization and oil suction rapidly and characteristics such as the oil suction multiple is bigger.
Claims (1)
1. the preparation method of a shaddock skin oil absorption material is characterized in that the concrete steps of this method are:
A. with after shaddock skin cleaning, the air-dry drying, remove the yellow appearance skin, make the square of 1 ~ 2cm, it is stand-by to be dried to constant weight again;
B. step a gained shaddock skin is immersed in the normal hexane, adds oleic acid, and drip the vitriol oil of catalyst levels, in 60～65 ℃, refluxed 5～7 hours; After filtration, after the normal hexane flushing, be dried to constant weight, namely get oil absorption material.
