Abstract
The present invention discloses vegetable wax extracting process. Sunflower husk as m is first soaked in organic solvent comprising C4-C6 petroleum product of boiling range 40-70 deg.c or C5-C5 gasoline of boiling range 40-100 deg.c; and the soaked liquid is filtered, distilled and cooled to obtain the vegetable wax product. The product is ivory or light yellow gel. The sunflower husk residue after extracting vegetable wax may be used as material for fiber board and household fuel.
Description
Technical field
The present invention be a kind of from plant the method for extracting effective components, the product that is obtained can be used as the raw material of light industry product.
Background technology
When at present vegetable oil mill was produced sunflower oil, the cot cutting under was except that the raw material of small part as fiberboard for building, and major part is burnt as household fuel, only several yuans of per hundred kilograms of prices.Contain the vegetable wax more than 3% in the sunflower shell,, can obtain remarkable economic efficiency if it is extracted.
Summary of the invention
The objective of the invention is to adopt the technology and the equipment of simple and feasible, vegetable wax contained in the sunflower shell is extracted, resourceful sunflower shell is turned waste into wealth, comprehensive utilization improves the economic and social benefits.
The extracting method of vegetable wax of the present invention is characterized in that using sunflower shell to do raw material, adds organic solvent and soaks.Solvent can be used oil C
4-C
6, 40～70 ℃ of boiling ranges; Or gasoline C
5-C
5, 40～100 ℃ of boiling ranges.Immersion liquid is distilled filtrate after filtering, gets product after the cooling.Finished product is a flaxen gelatinous solid after the oyster white.Distillatory solvent can use repeatedly through reclaiming.Sunflower shell residue behind the extraction vegetable wax can carry out the lixiviate second time, still can get the part finished product.Residue after the lixiviate for the second time still can be used as raw material or the household fuel of making fiberboard.
With the oil is the vegetable wax of solvent extraction, and productive rate is a little more than gasoline, and product is also purer, and distillation temperature is low, and the time is short, but save energy, but oil price is expensive, its cost is about 10 times of gasoline, so be feasible with gasoline extraction.For improving the quality of products, reduce solvent loss, reduce cost, the lixiviate container will seal tight, filters and waits operation to want rapidly.
Soak solvent for use and can be divided into the recovery of two steps, a part reclaims from the filtrate still-process, and the rate of recovery is 64%; Another part is the solvent recuperation that filter residue is adhered to, and filter residue is added an amount of water distill, and the rate of recovery is about 26%, and the total yield of the two reaches about 90%.
Effect of the present invention:
1, developed the approach of Sunflower Receptacle comprehensive utilization, made the per hundred kilograms of only agricultural organic waste of several yuans---sunflower shells, through extracting vegetable wax, its output value can reach more than hundred yuan, has remarkable economic efficiency.
That 2, extracts is simple for process, does not need complicated processing units, and less investment is easy to implement.
3, the sunflower shell residue behind the extraction vegetable wax still can be as the raw material or the household fuel of fibreboard made.
Embodiment
Embodiment 1: at first with the cot thorough drying, to improve crush efficiency, pulverize with pulverizer then, the thinner effect of extracting of pulverizing better.
With oil (C
4-C
6, 40～70 ℃ of boiling ranges) and when soaking, the weight of raw material and the volume ratio of solvent are 1: 5.Soak time is 24 hours, and temperature is about 25 ℃.Soak after-filtration, filtrate is placed in the water distilling apparatus distill, temperature is controlled at below 70 ℃, and distillation is cooled to get product below 28 ℃ after finishing.Filter residue continues to carry out the lixiviate second time with oil, still can get the part finished product.With gasoline (C
5-C
5, 40～100 ℃ of boiling ranges) and when being solvent soaking, the weight of raw material is 1: 6 with the solvent volume ratio.Soaking temperature is 20～25 ℃, and soak time is 24～36 hours.Filter then, filtrate is placed in the water distilling apparatus distill, temperature is controlled at below 100 ℃, if surpass 100 ℃ then finished product easily decompose charing, the blackening brown.Get product below the distillation postcooling to 28 ℃.In kind residue is carried out the lixiviate second time, still can get the part finished product.
Embodiment 2:
Do raw material with sunflower shell, through air-dry, pulverize after, inject industrial naptha (C
5-C
5, 40～100 ℃ of boiling ranges), the weight of raw material (gram) is 1: 6 with the ratio of solvent volume (milliliter), and soak time is 24～36 hours, and soaking temperature is 20～25 ℃; Then after filtration, filtrate distillation, temperature is 80～100 ℃, is cooled to below 28 ℃ again, gets product.
Claims (4)
1, a kind of extracting method of vegetable wax, it is characterized in that, use sunflower shell to do raw material, after raw material pulverizing, adding organic solvent soaks, the raw material of pulverizing (gram) and the ratio of solvent volume (milliliter) are that 1: 5～6 after filtering filtrates are distilled, and the distillatory temperature is 40～100 ℃, can obtain finished product after the cooling.
2, according to the method for the extraction of the described vegetable wax of claim 1, the ratio that it is characterized in that pulverizing back raw material weight (gram) and solvent volume (milliliter) is 1: 6.
3, the extracting method of vegetable wax according to claim 1 and 2 is characterized in that soak time is 24～36 hours.
4, the extracting method of vegetable wax according to claim 1 is characterized in that the distillatory temperature is controlled at 80～100 ℃.
