US6223449B1 - Apparatus for extracting plasticizer - Google
The apparatus described in FIG. 2 is utilized to extract plasticizer from composite separator electrodes containing plasticizer. As with the extraction described in Example 1, the decreased chamber pressure facilitates evaporation at a lower temperature than would be possible at normal atmospheric pressure.

Dextrose | Cargill
Dextrose. Crystalline dextrose is available as a powder in either monohydrate or anhydrous form. It is a widely used ingredient for medium culture preparations. Dextrose powder can also be used as a carrier for granulation of fermentation products. Crystalline dextrose, also known as glucose, is the fundamental monomer of all starchy products.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.
Beginners Guide to Soxhlet Extractions - Erowid
alternative to the traditional wet methods of solvent extraction is a Soxhlet type of apparatus which allows for near 100% active material recovery and user friendliness. The general In this mini-article we will explore efficient solid-liquid extractions using a Soxhlet type apparatus and application of theory to utility setups. GENERAL BACKGROUND
- How are plasticizers extracted from PVC?
- Plasticizers may account for 30–35% of the PVC formulation. Extraction and determination of plasticizers in PVC material are critical steps in evaluating a polymer for an intended use. Traditionally, plasticizers are extracted from PVC using a 6-h Soxhlet method and identified using infrared spectrometry or gas chromatography.
- What is a plasticizer in PVC?
- Plasticizers soften the polymer, aid in the manufacturing process, and provide form and function to various PVC materials. Plasticizers may account for 30–35% of the PVC formulation. Extraction and determination of plasticizers in PVC material are critical steps in evaluating a polymer for an intended use.
- What is accelerated solvent extraction?
- Accelerated solvent extraction is recognized as an oficial extraction method in U.S. EPA Method 3545. This Application Note outlines the basic principles of using accelerated solvent extraction to extract plasticizers such as dioctyl adipate (DOA), trioctyl phosphate (TOP), dioctyl phthalate (DOP), and trioctyl trimellitate (TOTM) from PVC.
