Extraction of plasticizers: An entire and reproducible quantification
Whitnack and Gantz [ 15] published an extraction for plasticizers from CA by using a Soxhlet extractor. Best results they obtained after a 20 hours extraction by using a 1:1 mixture of hexane and ethanol. However, they tested several solvents as methylene chloride, benzene, ethanol and hexane before.

Extraction of plasticizers: An entire and reproducible quantification
Plasticizers from historical artefacts made of cellulose acetate were extracted and quantified. In compare to common procedures the presented method led to an entire and reproducible extraction which can even be performed in a much shorter time. The success of the improved procedure is based on the use of ultrasonic sound, methanol as solvent and multiple extraction steps for a complete
Application of an MOF-based dispersive micro solid phase extraction
The current study aims at the extraction and preconcentration of some plasticizers, including dimethyl phthalate, diethyl phthalate, di-iso-butyl phthalate, di-n-butyl phthalate, di-(2-ethylhexyl) adipate, and di-iso-octyl phthalate, migrated into different samples (mineral water, injection serum, orange juice, and carbonated soft drink) using MIL-68 (Al) in a dispersive micro solid phase
- How to extract plasticizers from cellulose acetate?
- Conclusion A new method to extract plasticizers from cellulose acetate could be developed. Using ultrasonic sound leads to significant time savings compared to previous extraction methods. Cutting the sample into small chips leads to an increase of extraction efficiency.
- How do you extract plasticizers from ca?
- Whitnack and Gantz published an extraction for plasticizers from CA by using a Soxhlet extractor. Best results they obtained after a 20 hours extraction by using a 1:1 mixture of hexane and ethanol. However, they tested several solvents as methylene chloride, benzene, ethanol and hexane before.
- How can a plasticizer be removed?
- In compare to common procedures the presented method led to an entire and reproducible extraction which can even be performed in a much shorter time. The success of the improved procedure is based on the use of ultrasonic sound, methanol as solvent and multiple extraction steps for a complete removal of the plasticizers.
- How to extract plasticizers from methanol?
- It could be found out that methanol is in combination with ultrasonic sound the most efficient solvent. Four extraction steps are sufficient to achieve a total extraction of the plasticizers. The ultrasonic sound extraction is a simple method which can be used in laboratories and workshops without larger investments.
- What happens if plasticizers migrate out of a polymer?
- The plasticizers diffuse between the polymer chains and increase intermolecular space which is necessary for changes in shape, flexing and moulding of the material [7, 11]. If the plasticizers migrate out of the polymer, it becomes brittle. The loss of plasticizers along with deacetylation results in loss of mass and shrinkage of the polymer .
- Can plasticizers be removed completely with ethanol?
- In summary, even after seven extraction steps it was not possible to remove the plasticizers completely with ethanol or with a mixture of 1:1 (v:v) ethanol and hexane. Only with methanol it was possible to remove all plasticizers with three extractions.
