Abstract
The present invention is a kind of method of extracting vegetable wax from sunflower shell.The method of extracting is with raw material pulverizing, and the immersion of adding organic solvent, filtration, distillation, cooling promptly get product.Organic solvent after the distillation is recyclable to be used repeatedly.
It is abundant to the invention provides a kind of raw material sources, with low cost, extracts the simple method of equipment and technology.The product that is obtained can be as the raw material of light industry products such as makeup, shoe polish, polishing wax.For the comprehensive utilization of Sunflower Receptacle opens up a new way, thereby obtain bigger economic benefit.
Description
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.
When at present vegetable oil mill was produced sunflower oil, the cot that peels was most ofly burnt as household fuel except that the raw material of small part as fiberboard for building, 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.
Design of the present invention is CAB and patent database by retrieval, does not all detect pertinent literature.
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 is increased economic efficiency and social benefit.
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 sherwood oil C
4-C
8, 40～70 ℃ of boiling ranges; Or gasoline C
5-C
8, 40～100 ℃ of boiling ranges.Immersion liquid is distilled filtrate after filtering, gets product after the cooling.Finished product is oyster white or flaxen gelatinous solid.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 as raw material or the household fuel of making fiberboard.
Solution of the present invention can be further technical process by extracting method be illustrated.
Residue lixiviate for the second time
Raw material → pulverizing →
→ cooling → finished product
Specific implementation method is that at first with the cot thorough drying, to improve crush efficiency, then with the pulverizer pulverizing, the thinner effect of extracting of pulverizing better.
With sherwood oil (C
4-C
8, 40～70 ℃ of boiling ranges) and when soaking, the weight of raw material and the volume ratio of solvent are 1: 5, and 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 sherwood oil, still can get the part finished product.
With gasoline (C
5-C
8, 40～100 ℃ of boiling ranges) and when being solvent soaking, the weight of raw material is 1: 6 with the solvent volume ratio, and 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.
By table as seen, the extracting effect of different solvents is discrepant.With the sherwood 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 the sherwood 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%.
Most preferred embodiment:
Do raw material with sunflower shell, through air-dry, pulverize after, inject industrial naptha (C
5-C
8, 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.
Effect of the present invention:
1. developed the approach of sunflower comprehensive utilization, made per hundred kilograms of only agricultural organic waste-sunflower shells of several yuans, through extracting vegetable wax, its output value can reach more than hundred yuan, has significant economic benefit.
2. that extracts is simple for process, does not need complicated process equipment, and small investment is easy to implement.
3. the sunflower shell residue behind the extraction vegetable wax still can be as raw material or the domestic fuel of fibreboard made.
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, add organic solvent and soak, the ratio of raw material of pulverizing (gram) and solvent volume (milliliter) is 1: 5～6, and filtrate is after filtering distilled, the distillatory temperature is 40～100 ℃, can obtain finished product after the cooling.
2, method according to claim 1, the ratio of raw material weight (gram) and solvent volume (milliliter) is 1: 6 after it is characterized in that pulverizing.
