Abstract

The invention relates to a method for extracting mannitol in kelp. The method comprises the following steps: selecting raw materials, soaking, shearing, crushing, performing nanometer milling, regulating the pH value, filtering, neutralizing, concentrating, performing ethanol precipitation, and drying, thereby obtaining the finished product. The method disclosed by the invention has the beneficial effects that the design is reasonable, the process period is effectively shortened, and the dissolution rate of the unit product is greatly improved by virtue of a nanometer wall-breaking technology. Meanwhile, the yield is improved, the energy consumption is reduced, the operating safety is guaranteed, and the method is an ideal selection of industrial production.

Description

A kind of method extracting N.F,USP MANNITOL in sea-tangle
Technical field
The present invention relates to technical field of marine animal extraction, be specifically related to a kind of method extracting N.F,USP MANNITOL in sea-tangle.
Background technology
N.F,USP MANNITOL is the isomers of Sorbitol Powder, and it can as good diuretic(s) at field of medicaments, reduces the medicine of intracranial pressure, intraocular pressure and treatment kidney, also can be used as the thinner of the vehicle of tablet and solid, liquid.The one of to take N.F,USP MANNITOL as the formula mannitol injection liquid of main component be clinical rescue brain disorder is commonly used height and is oozed depressor.At field of food, N.F,USP MANNITOL due to the water-absorbent in sugar and sugar alcohol minimum, and there is sweet taste, can be used as the sweeting agent of the anti-stick powder of cake and food with low sugar content.At field of industrial production, be that poly-N.F,USP MANNITOL-propylene oxide ether that initiator is made is widely used in plastic industry with N.F,USP MANNITOL.Apply so widely based on N.F,USP MANNITOL, how to extract high-quality N.F,USP MANNITOL fast and efficiently, thus meet the heavy demand of industrial application, be the research emphasis of person skilled always.Industrial production N.F,USP MANNITOL mainly contains two kinds of techniques in the world, and one take sea-tangle as raw material, and one is for raw material with sucrose and glucose, and the existing method extracting N.F,USP MANNITOL from sea-tangle mostly to there is process cycle long, output is lower, and energy consumption is high, and operational safety can not get the shortcomings such as powerful guarantee.
Therefore, need badly and design and develop a kind of method extracting N.F,USP MANNITOL from sea-tangle newly, to solve prior art above shortcomings.
Summary of the invention
The object of this invention is to provide a kind of method extracting N.F,USP MANNITOL in sea-tangle, to overcome currently available technology above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
Extract a method for N.F,USP MANNITOL in sea-tangle, comprise the following steps:
First, choose raw material, described raw material comprises sea-tangle, sulfuric acid, calcium hydroxide and ethanol;
Secondly, pulverized by sea-tangle, be soaked in water, the quality of described water is 10 times of sea-tangle quality, soaks, in the stirred pot with shearing function, carries out shearing-crushing to sea-tangle;
Again, the solution of nanometer sand mill to shearing-crushing is used to mill, until cytoclasis;
Again, utilize sulphuric acid soln that solution ph is adjusted to 2;
From secondary, filter the gluey macromolecular substance of remove portion;
Then, add aqua calcis and neutralize, cross and filter insoluble substance;
Finally, adopt mechanical steam recompression technology to be concentrated into 1/4 of original volume to solution, then the volume fraction adding concentrated rear solution 2 times amount is the ethanol of 95%, stir, collected by centrifugation canescence bulk precipitate thing, dries it, obtains finished product N.F,USP MANNITOL.
Further, described soak time is 2 hours.
Further, the volume fraction of described sulfuric acid is 10%.
Further, the add-on of described aqua calcis is 1.0 mg/ml.
Beneficial effect of the present invention is: reasonable in design, effectively shortens process cycle, and nanometer wall breaking technology greatly improves the solubility rate of unit product, improves output simultaneously, reduces energy consumption, has ensured processing safety, is the ideal chose of suitability for industrialized production.
Embodiment
The embodiment be clearly and completely described the technical scheme in the embodiment of the present invention is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of protection of the invention.
Embodiment 1:
According to embodiments of the invention, provide a kind of method extracting N.F,USP MANNITOL in sea-tangle, specifically comprise the following steps:
First, choose raw material, described raw material comprises sea-tangle, sulfuric acid, calcium hydroxide and ethanol;
Secondly, pulverized by sea-tangle, be soaked in water, the quality of described water is 10 times of sea-tangle quality, soaks 2 hours, in the stirred pot with shearing function, carries out shearing-crushing to sea-tangle;
Again, the solution of nanometer sand mill to shearing-crushing is used to mill, until cytoclasis;
Again, utilize 2% sulphuric acid soln that solution ph is adjusted to 2;
From secondary, filter the gluey macromolecular substance of remove portion;
Then, the aqua calcis adding 1.0 mg/ml neutralizes, and crosses and filters insoluble substance;
Finally, adopt mechanical steam recompression technology to be concentrated into 1/4 of original volume to solution, then the volume fraction adding concentrated rear solution 2 times amount is the ethanol of 95%, stir, collected by centrifugation canescence bulk precipitate thing, dries it, obtains finished product N.F,USP MANNITOL.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
