Description
Technical field
The utility model relates to the separatory funnel based on carbon tetrachloride precipitation assays, belongs to separatory funnel field.
Background technology
Separatory funnel is a kind of glass experiment instrument, particularly relates to a kind of separatory funnel doing chemical experiment.Comprise bucket body, cover at bucket body bucket cover suitable for reading.Bucket body end opening installs the piston of a three-port structure, and two reduction of fractions to a common denominators of piston are not connected with twice pipes.Use the utility model, experimental implementation process can be made to be beneficial to control, reduce labour intensity, when the amount of liquid needing to be separated is large, kind of the liquid of two in bucket body can be flow to lower pipe by three defaecations only need moving piston simultaneously, just can once complete without the need to changing container.Then the speed controlling chemical reaction at the Main Function of Junior separatory funnel.This device is the good experimental ware of a kind of function in scientific research, chemical experiment.The neck of separatory funnel has a piston, and this is that it is different from the major reason of common funnel and long neck funnel, because the neck of common funnel and long neck funnel does not have piston, it can not control liquid flexibly.Cock core on filler neck will be taken out by separatory funnel before use, coats vaseline, but can not be too many, in order to avoid blocked flow fluid apertures.Separatory funnel is inserted in plug groove to rotate and make oil film homogeneous transparent, and rotate freely.Then cut-out tap, water filling in funnel, checks whether cock place leaks, and watertight separatory funnel can use.The amount of liquid added in funnel can not exceed 3/4 of volume.And should not akaline liquid be filled.For preventing impurity from falling in funnel, the stopper in bell mouth should be covered.During use, left hand tiger's jaw withstands funnel ball, controls liquid feeding with thumb forefinger rotating piston.Now the sulculus of glass stopper will communicate with bell mouth side apertures align, and just just liquid feeding carries out smoothly.When the liquid in separatory funnel is to time dirty, the flow of piston controllable liquid, to cessation reaction, will be closed tightly by piston, therefore, can stop immediately dripping liquid.During tapping, the groove on grinding port plug will be aimed at the aperture on bell mouth neck, and the air at this moment inside and outside funnel communicates, and pressure is equal, and the liquid in funnel could flow out smoothly.According to the principle of " dirty upper " during separatory, open piston and all flow out by lower floor's liquid, closure piston.Upper strata is poured out from suitable for reading.Separatory funnel can not heat.Funnel with after want washes clean.Long-time no separatory funnel cock place wiped clean, will be put a paper slip between plug core and plug groove, and entangles piston with an elastic, in case frosted place adhesion.
Carbon tetrachloride is a kind of colourless liquid, many kinds of substance such as energy dissolved fat, paint etc., volatile, nonflammable liquid.Micro-sweet gas taste of tool chloroform.Molecular weight 153.84, at normal temperatures and pressures density 1.595g/cm
3(20/4 DEG C), boiling point 76.8 DEG C, vapour pressure 15.26kPa (25 DEG C), vapour density 5.3g/L.Carbon tetrachloride and water immiscible, time more than 500 degree can with water effect, produce poisonous phosgene and hydrochloric acid, can be miscible with ethanol, ether, chloroform and benzinum etc.Chance fire or red-hot thing can be analyzed to carbon dioxide, hydrogen chloride, phosgene and chlorine etc.Carbon tetrachloride was once widely used as the dry cleaning agent of solvent, extinguishing chemical, organic chlorinating agent, the leaching agent of spices, the degreasing agent of fiber, the digestant of grain, the extractant of medicine, organic solvent, fabric, but the relation due to toxicity is now very few to be used and is limited production, a lot of purposes also substitute by carrene etc.Also can be used to the monomer synthesizing fluorine Lyons, nylon 7, nylon 9; Also can chloroform processed and medicine; Lubricant is used as in metal cutting.
Separatory funnel during current carbon tetrachloride precipitation method detection mixed feed mixture homogeneity is the common separatory funnel of integral structure, common separatory funnel due to liquid seperating plug aperture little, feed deposited components cannot descend Lou, cause experimental data inaccurate, and integral structure clean very inconvenient after detecting.
Utility model content
