Abstract
The invention provides a method for testing the liquid water content of a plant, wherein, the method is characterized in that gum turpentine is taken as solvent; steam which is generated by heating up a materiel and the solvent to be boiled enters into a condensation pipe; the stem is condensed to reflow into a receiving pipe; the step of heating is stopped after the reflow liquid in the receiving pipe is not increased; and the liquid water content of the plant can be calculated according to a prior equation after testing the volume of the reflow liquid. When testing the moisture of the plate with the invention, the solvent is nontoxic and harmless; the cheap gum turpentine is no harm to human health, is convenient to recycle, can greatly reduce the cost of the solvent during batch production, reduces unnecessary waste, and saves resource; and the method has high testing precision, exact liquid water content, and is suitable for testing the liquid water content of various plates, dried fruits, etc.
Description
Technical field
The present invention relates to a kind of moisture determination method, especially the assay method of a kind of plant water cut belongs to technical field of analytical chemistry.
Technical background
In plant extract, plant component are analyzed, usually relate to the mensuration of plant water cut.Existing technical standard all with poisonous and harmful and expensive organic chemical reagent such as toluene or dimethylbenzene etc. as solvent, not only be detrimental to health and surrounding environment, and used this kind solvent is difficult to recycle, and is the main cause that causes the plant extract cost high all the time.Therefore, be necessary fully prior art is improved.
Summary of the invention
For the toxic solvent that overcomes the prior art existence endangers greatly, the cost height is difficult to recycle, deficiencies such as serious waste of resources the invention provides a kind of nontoxicly, and cost is low, the recyclable utilization of solvent, plant moisture content assay is the assay method of plant water cut accurately.
The present invention realizes by following technical proposal: the assay method of a kind of plant water cut is characterized in that with the gum turpentine being solvent, process the following step:
A, press material: the mass ratio of solvent=1: 1～2, material and solvent are together joined in the well heater, add the zeolite of an amount of anti-bumping simultaneously;
B, adding the solvent identical to completely respectively with in the distillation receiver pope that well heater and cold doubtful device are communicated with the A step;
C, intensification add thermal material and extremely boiling of solvent, and the steam that is produced rises and enters in the condenser, and control steam lifting height to 1/5 of condenser height is sentenced down;
D, the plant extracts that is condensed into liquid through C step condenses device flow into the distillation receiver pope bottom of condenser below along wall, will distills the interior solvent of receiver pope simultaneously and enter in the well heater from top, continue to finish solvent extraction;
E, when the extract of distillation receiver pope bottom no longer rises, stop heating, make extract be cooled to room temperature after, undermost moisture content volume is read in moisture content in the extract and oil content layering, can calculate water content.
The zeolite of described A step is commercial product, and its addition is exceeded can prevent the quick-fried expense of material and solvent.
The moisture content volume that described E step obtains is calculated as follows out water content:
In the formula: water layer capacity in the V-distillation receiver pope, mL; The weight of W-sample, g.
Described gum turpentine solvent is commercial product, and its boiling point is higher than the boiling point of water, and immiscible with water, nontoxic, cheap.
The present invention has following advantage and effect: when adopting such scheme to measure plant moisture content, its solvent for use is nontoxic, cheap gum turpentine, and health is not had any harm, be easy to recycle, can reduce solvent cost greatly during batch process, reduce unnecessary waste, economize on resources, during simultaneously with the moisture content in the gum turpentine mensuration plant, its measuring accuracy height, water cut is accurate, is suitable for measuring water contents such as all kinds of plants, dry fruit.
Description of drawings
Fig. 1 is a moisture determination structure drawing of device of the present invention.
Among the figure, 1 is well heater, which is provided with gateway 2,4 are the distillation receiver pope, its top is provided with gateway 5, the middle and upper part is provided with distillation cascade 3, distillation cascade 3 lower ends place on the gateway 2 of well heater 1 by bottle stopper 12, thereby well heater 1 is communicated with distillation cascade 3, and 6 is condenser, by being positioned at inner condensation straight tube 7, and being positioned at outside cooling collar 8 formations, cooling collar 8 is provided with cooling liquid inlet 9 and outlet 10, the upper end closed of condensation straight tube 7, the lower end places on the gateway 5 at distillation receiver pope 4 tops by bottle stopper 11, thereby condensation straight tube 7 is communicated with distillation receiver pope 4.

A, anistree by doing: the mass ratio of gum turpentine=1: 1, do 15 grams anistree and 15 restrain gum turpentines and together join in the well heater 1, add the zeolite of 3 ~ 4 anti-bumpings simultaneously;
B, distillation cascade 3 lower ends that will distill receiver pope 4 place on the gateway 2 of well heater 1 by bottle stopper 12, add the upper port below that gum turpentine to the middle and upper parts of distilling receiver pope 4 are positioned at distillation cascade 3 from the gateway 5 at distillation receiver pope 4 tops, place the lower end of condensation straight tube 7 on the gateway 5 at distillation receiver pope 4 tops by bottle stopper 11;
C, well heater 1 is placed on the electric furnace, heating do anistree and gum turpentine to boiling, the steam that is produced rises through distillation cascade 3 and enters in the condensation straight tube 7, and control steam lifting height is to condensation straight tube 7 1/5 sentencing down highly;
D, the plant extracts that becomes liquid through the C step condenses flow into distillation receiver pope 4 bottoms of its below along the tube wall of condensation straight tube 7, and the gum turpentines in the distillation receiver pope 4 are entered in the well heater 1 through distillation cascade 3, continue to finish solvent extraction;
E, when the extract of distillation receiver pope 1 bottom no longer rises, stop heating, make extract be cooled to room temperature after, moisture content in the extract and oil content layering, reading undermost moisture content volume is 2.9ml, as calculated anistree water content is 19.33%.
