Acetone Recovery in Composite Cleaning Applications

February 22, 2022 / by CBG Biotech posted in acetone

0 Comments

Acetone is a durable solvent often used in composite cleaning applications. Because Acetone possesses strong dissolution characteristics, it can absorb relatively high concentrations
of epoxy, polyester and vinyl ester in composite cleaning applications.

Eventually, the Acetone will become saturated with this epoxy, polyester and vinyl ester waste. Once saturated, the Acetone will need to be disposed of (incinerated) and replenished (purchased). Both disposal and acquisition expend the resources of a composite manufacturer.

Use of Acetone in Composite Cleaning

February 15, 2022 / by CBG Biotech posted in Industrial, acetone

0 Comments

Acetone is a potent chemical solvent that is frequently used to clean, degrease, strip lacquers, waxes, resins and paints. For this reason, Acetone is commonly used in varied industrial applications.

In composite applications, Acetone will dissolve and remove epoxy, polyester and vinyl ester resin from tools, brushes and surfaces. Acetone will effectively remove wax and grease for surface preparation prior to bonding.

Acetone possesses strong characteristics for use in composite cleaning applications such as:

Carrier Solvents in Extraction:

Ethanol vs Butane

It is true, both Ethanol and Butane (also referred to as Hydrocarbon) can be used to extract oil from cannabis and hemp. When considering which solvent to use, a processor should carefully review the safety, efficacy and working history of a given solvent in application. Operating costs can be masked and provide a false positive to select a solvent because it is less expensive to purchase, when, it is more expensive to use. This blog will explain some of these differences between Ethanol and Butane and will help guide a processor to make more informed and better decisions regarding extraction methods and carrier solvents used in these same extraction methods.

Essential oil extractions are performed to obtain important and valuable ingredients from plant matter and have been occurring for centuries. Early pharmaceuticals utilized extraction techniques in medicine and still today extractions from plant matter are used to obtain critical oils that are used in manufacturing medicines. An example of this is the use of yam biomatter to extract precursors for the intermediate of testosterone. Extractions are also performed to obtain many of today’s fragrances.

Purity vs Concentration of a Solvent: Which One Affects Parts Washing Effectiveness?

December 2, 2020 / by CBG Biotech

3 Comments

Purity can be an important measurement for organic solvents, one which an end user will often consider prior to purchase of a solvent. In parts washing applications, purity of an organic solvent is not necessarily the best measurement for effectiveness in application and solvent concentration needs to be carefully considered.
