Abstract
Castor seeds is through clearing up, roll embryo, steaming stir-fry, and a part of Viscotrol C is produced in pre-earlier press for extracting juice (or squeezing), uses the residue grease in alcohol (also claiming aqueous ethanol) the leaching Semen Ricini cake then.The moisture requirement of pre-pressed cake is 2～14%, 50～90 ℃ of extraction temperatures, and the ratio of alcohol and Semen Ricini cake is 1: 0.6～1.2, extraction time 60～120 minutes.Mixing oil separates through precipitation, filtration, evaporation and stripping, and isolated alcohol recycles through condensation and rectifying.Pre-pressed crude oil and leaching crude oil are handled through precipitation, filtration, depickling and decolouring and are made industry or pharmaceutical Viscotrol C.Residual oil is below 1% in the castor-oil plant dregs of rice that this law is handled.
Description
The invention belongs to grease, chemical technology field, be specifically related to the method with the solvent extraction Viscotrol C, its international Patent classificating number is BO1D.
Viscotrol C is a kind of broad-spectrum industrial chemicals, is mainly used in manufacturing synthetic resins, coating, lubricating oil and softening agent etc., and the auxiliary material of medicine, printing and dyeing and tanning industry.
Existing Viscotrol C working method has following several: a kind of be with castor seeds after cleaning, adopt whole seed cold press to get oil, general cold press secondary is obtained Viscotrol C quality height with this legal system, weak point is that oil yield is low.Another kind be with castor seeds through pre-treatment, under higher temperature and lower moisture condition, produce a part of Viscotrol C earlier then with pre-squeezer, use No. 6 solvents (normal hexane) to leach Viscotrol C in the Semen Ricini cake then.Because Viscotrol C is rich in ricinoleic acid (content is 82～88%), makes the specific inductivity of Viscotrol C bigger, promptly polarity is bigger.And the specific inductivity of No. 6 solvents is less, belong to non-polar solvent, can not dissolve mutually with arbitrary proportion and Viscotrol C at normal temperatures, cause the residual oil content that leaches the dregs of rice higher, general (Zhao Furong: the discussion of castor seeds pre-pressing extraction technology about 3.5%, oil technology, Xi'an oil research institute of the Ministry of Commerce, 1980(3)).CN86103319A on February 11st, 1987 disclosed " comprehensive utilization of castor seeds " introduces and castor seeds is shelled shell, benevolence separate machined with peeler; Castor seeds Renhe ethanol is pressed extraction through a mill, three collections, three, again through underpressure distillation, obtains the method for thick oil and slag.Its weak point is: alcoholic acid reclaims relatively difficulty, needs to adopt the ternary azeotropic distillation dehydration or add the dewatering agent distillation dehydration, and energy consumption is big, production cost is high; And Residual oil height in the dregs of rice is not seen the relevant concrete measure that shells in addition.
The present invention spills the smart method that leaches Viscotrol C for overcoming a kind of usefulness that above-mentioned deficiency studies.
Purpose of the present invention can reach by following measure: castor seeds is removed various impurity through cleaning equipment, rolls embryo with flaker then, rolls material (being called embryo) behind the embryo and advances cooking pot and steam and fry, and follows into pre-squeezer (or oil press zhai) squeezing.The expressed crude oil is treated as the refining Viscotrol C through precipitation, filtration, depickling, decolouring or deodorization.Pre-pressed cake is gone into leacher through fragmentation.The moisture controlled of pre-pressed cake is 2～14%, and oil-containing is controlled at below 15%, and the concentration that leaches solvent alcohol is 70～95%, 50～90 ℃ of extraction temperatures, and the ratio of alcohol and pre-pressed cake is 1: 0.6～1.2,60～120 minutes processing condition of extraction time leach.The mixing oil that leaches (Viscotrol C and the mixture that spills essence) filters through precipitation, strainer, and evaporating pot evaporation, stripping tower are isolated alcohol, make it to become the leaching Viscotrol C.Leach Viscotrol C and become the refining Viscotrol C through precipitation, filtration, depickling, decolouring and deodorizing technology process again.The wet dregs of rice that leacher comes out are gone into the evapo-separated machine evaporation and are separated alcohol, and the dregs of rice that evapo-separated machine comes out can be made fertilizer, or further processing system feed.The isolated alcohol of flash-pot, stripping tower and evapo-separated machine is through condensation, branch water and rectifying recycling use.
Detect the acid number and the color and luster that leach Viscotrol C, make alkali lye, will leach Viscotrol C and be warming up to 60 ℃ by acid number preparation when concentration, under whipped state, added alkali lye, continue to stir neutralization in 15 minutes, treat that oily soap begins when separating to heat up, speed by 1 ℃ of per minute liter is warming up to 80 ℃, and then to add concentration be that 5% the oil that accounts for weighs 20～40% common salt aqueous solution, then continues to be warming up to 90～100 ℃.Staticly settled 40～50 minutes, and emitted separation waste water, and wash be neutrality to waste water 2～3 times till.Under vacuum state, dewater.Dehydration finishes oily temperature rise to 90～100 ℃, adds to account for oil and weigh 1～3% gac and account for oil and weigh 3～5% carclazyte decolouring, when treating oily temperature drop to 70～80 ℃ after the decolouring, filters and removes carclazyte and gac, goes into the deodorizing tank deodorization at last, promptly gets the refining Viscotrol C.See attached list with the Viscotrol C quality that the inventive method is produced.Optimum process condition of the present invention is:
Ethanol concn 90%, 80 ℃ of extraction temperatures, the ratio 1: 1.1 of spilling smart and Semen Ricini cake, extraction time 120min, the moisture content 8% of pre-pressed cake contains Viscotrol C and is controlled at below 10% in the Semen Ricini cake.
The subordinate list Semen Ricini cake leaches the leading indicator of crude oil and refining Viscotrol C
The advantage that the present invention had is
1, adopt alcohol to make the solvent extraction Viscotrol C, reaction of degeneration does not take place, has guaranteed the use value of Viscotrol C as good technical oils in positions such as the hydroxyl of ricinoleic acid, two keys.
2, be applicable to existing pre-press for extracting juice-leaching grease production technology, need do not increase any equipment, can produce Viscotrol C.
3, leach the oil yield height, residual oil content is low in the dregs of rice.
4, alcohol is a kind of biological renewable solvent, and it originates sufficient, and price is low, and consumption is low, easily reclaim, but save energy, and pollution-free.
5, obtained Viscotrol C quality better, the quality of the dregs of rice is also high, the outward appearance look shallow.Can be for further exploitation.
Accompanying drawing is embodiments of the invention
Fig. 1 is that castor seeds presses-alcohol extract technology schema in advance.
Fig. 2 is the refinery practice schema that presses Viscotrol C in advance, leaches Viscotrol C.
The optimal processing parameter of present embodiment is:
Concentration is 90% the essence of spilling, 80 ℃ of extraction temperatures, and spilling smart ratio with Semen Ricini cake is 1: 1.1, extraction time 120min, the water content of pre-pressed cake is 8%, the Residual oil in the Semen Ricini cake is below 10%.
