Abstract
The utility model discloses a kind of special phthalic ester plasticizer extraction of ultrasonic wave and purification servicing unit, the polytetrafluoroethylene (PTFE) lid installed including glass container bottle and with glass container bottle using screw thread screw-fashion, polytetrafluoroethylene (PTFE) lid is provided with the changeable type polytetrafluoroethylene (PTFE) miillpore filter for being provided with and being located at below teflon valve in teflon valve, polytetrafluoroethylene (PTFE) lid.Whole polytetrafluoroethylene (PTFE) lid and teflon valve are that polytetrafluoroethylene (PTFE) material is made, and will not be corroded by organic solvents such as dichloromethane；Glass container bottle and polytetrafluoroethylene (PTFE) lid are by the way of screw thread is screwed, and the low boiling such as dichloromethane, volatile organic extraction solvent are not susceptible to leakage；Replaceable polytetrafluoroethylene (PTFE) miillpore filter is set in polytetrafluoroethylene (PTFE) lid, teflon valve filtration, purification can be directly opened after the completion of extraction, scavenging solution can directly upper machine testing, reduce the loss of target detection thing about 5% 10%, save about 10 minutes pre-treatment time.
Description
Technical field
The utility model is related to a kind of structure for extracting and purifying one, more particularly to the special phthalic acid ester of ultrasonic wave
Class plasticizer is extracted and purification servicing unit.
Background technology
At present, the existing phthalic ester plasticizer extraction special without ultrasonic wave and purification servicing unit, tradition
Way be all usually using common glass spinner flask（With bottle stopper）Sample and appropriate organic solvent are contained as container
Extract, then by filtering with microporous membrane purification.
Because Extraction solvent is usually that dichloromethane, chloroform, n-butyl acetate etc. are that the relatively low toxicity of boiling point has
Machine solvent, volatility is extremely strong, after being extracted using conical flask as container, then is purified through filtering with microporous membrane, and this process is only
It is two steps, easily making the organic solvent gas of volatilization may reveal from grournd glass lid, to experiment operator body
Body health causes very big harm.
In addition, need to be purified in extract solution through filtering with microporous membrane, secondary operation can increase the pre-treatment time about 10 minutes, and
Bring more uncertain factors into, cause the loss about 5%-10% of target detection thing, there is very big unfavorable to the accuracy of detection
Influence.
The content of the invention
The purpose of this utility model is that there is provided a kind of special adjacent benzene two of ultrasonic wave in order to overcome the shortcoming of above-mentioned prior art
Formate ester plasticizer is extracted and purification servicing unit, and the special phthalic ester plasticizer of the ultrasonic wave is extracted and purified auxiliary
Help device that the hypertoxic organic solvent volatilization such as dichloromethane during extraction phthalic ester plasticizer can be avoided to reveal, will filter
Purifier is incorporated into extraction equipment, reduces the loss of Objective extraction thing, saves the pre-treatment time.
The utility model solves the technical scheme that its technical problem used：A kind of special phthalic acid ester of ultrasonic wave
Class plasticizer is extracted and purification servicing unit, including glass container bottle and is installed using screw thread screw-fashion with glass container bottle
Polytetrafluoroethylene (PTFE) lid, polytetrafluoroethylene (PTFE) lid, which is provided with teflon valve, polytetrafluoroethylene (PTFE) lid to be provided with to be located at, to be gathered
Changeable type polytetrafluoroethylene (PTFE) miillpore filter below tetrafluoroethene valve.Whole polytetrafluoroethylene (PTFE) lid and polytetrafluoroethylene (PTFE) valve
Door is that polytetrafluoroethylene (PTFE) material is made, and will not be corroded by organic solvents such as dichloromethane；Glass container bottle and polytetrafluoroethylene (PTFE)
Lid is by the way of screw thread is screwed, and the low boiling such as dichloromethane, volatile organic extraction solvent are not susceptible to leakage；Poly- four
Replaceable polytetrafluoroethylene (PTFE) miillpore filter is set in PVF lid, polytetrafluoroethylene (PTFE) valve can be directly opened after the completion of extraction
Door filtration, purification, scavenging solution can directly go up machine testing, reduce the loss about 5%-10% of target detection thing, save the pre-treatment time about
10 minutes.
Further, described changeable type polytetrafluoroethylene (PTFE) miillpore filter is 0.45 μm of PTFE miillpore filter.
Further, described glass container bottle is provided with the scale of metered capacity.
In summary, the special phthalic ester plasticizer extraction of ultrasonic wave of the present utility model and purification servicing unit
Compared with prior art, the hypertoxic organic solvent volatilization such as dichloromethane when can avoid extraction phthalic ester plasticizer
Leakage；Filtering and purifying, extraction equipment are united two into one, the loss about 5%-10% of Objective extraction thing is reduced, pre-treatment is saved
About 10 minutes time.
