The Process of Liquid Liquid Extraction

The Process of Liquid-Liquid Extraction

What is Liquid-Liquid Extraction?

Liquid-Liquid extraction is a more complex process of separating a liquid mixture over the Liquid-Solid process. Another common term for Liquid-Liquid extraction is as solvent extraction process. The process involves taking liquids, mixing them, and being able to separate them when the liquid settles. Often one part is water while the other can be an organic solvent. The process is illustrated below:

THE EXTRACTION PROCESS

The process involves having an immiscible mixture, represented by A+C and B the parts can be transferred and mixed, and separated. It extracts a solute from a two-part solution by being brought together with another non-homogenous solvent where that solute can be dissolved. From this, the liquid mixtures are isolated with the solutes that can be dissolved distribute where necessary.

Solvents Used in Liquid-Liquid Extraction

While in a Liquid-Solid extraction water is the most common solvent used, in Liquid-Liquid extraction Diethyl Ether is most commonly used. Since the process for Liquid-Liquid extraction requires immiscible solvents things like ethanol and acetone should not be used because they mix with water. Therefore, the listed solvents below are recommended for Liquid-Liquid extraction:

  • Hexane
  • Diethyl Ether
  • Dichloromethane
  • Toluene

All are more commonly chosen for the organic solvent used in this extraction process.

Liquid-Liquid Extraction Uses

There are several processes that require Liquid-Liquid extraction and here are some of the most common uses below:

  • Fermentation
  • Pharmaceuticals
  • Fragrances
  • Food Products
  • Agriculture Chemicals

You can refer to our blog about Liquid-Solid extraction to examine that these two types of extraction methods are used in repetitive industries. So, in a way, they go together at times in terms of their common uses and processes within these industries.

Solvent extraction or Liquid-Liquid extraction is a process that relies heavily on the use of proper solvents. If you have more questions or need more information on the solvents for extractions, we have answers contact us here at Ecolink!

The Process of Liquid Solid Extraction

The Process of Liquid-Solid Extraction

What is Liquid-Solid Extraction?

The process of Liquid-Solid Extraction happens quite often in chemical processes. They range from everyday products a person uses to more industrial uses, which will be discussed later. Liquid-Solid extraction is the process by which solvents are merged with solid material and the non-dissolvable parts are extracted and the liquid parts stay.

What Solvents Are Used in Liquid-Solid Extraction?

While Water is the most commonly used solvent for Liquid-Solid extraction, there are a few other liquids that are associated with the extraction process and are used for different types of materials:

  • Diethyl Ether
  • Methylene Chloride
  • Ethyl Acetate
  • Hexane
  • Toluene

What is Liquid-Solid Extraction Used For?

Since there are many solvents used to derive liquids from solids, there are many different industries and products that put this process into practice. Some of the most regular uses of Liquid-Solid extraction are:

  • Pharmaceuticals
  • Oil from seeds
  • Metal Salts
  • PCBs derived from Fish
  • Coffee Brewing
  • Tea Brewing
  • Beer Brewing

Liquid-Solid Extraction serves multiple purposes in Chemistry and everyday life and work. The ranges of uses go from big industry pharmaceuticals to right on your corner coffee store or favorite beer brewery. Depending upon the type of substance requiring liquid extraction from it, different solvents need to be used for accurate extraction techniques. It is a simple process that is more common than people believe it to be or realize what it is and does.

MELODY INTERNSHIP

Melody’s Internship Experience

Who Am I?

My name is Melody Weckel Confer. I was a Digital Marketing Intern with Ecolink Inc. during the Summer of 2018. This was my first internship and Ecolink was the ideal company to work for. My director supervisors and my intern co-workers were extremely helpful and collaborative. I have gone on to recommend this opportunity to others at my college and in the Atlanta area.

What I Did I Do?

Ecolink gave me valuable experience that allowed me to obtain two subsequent marketing internships, one with the Professional Photographers of America, and one with the Piedmont National Corporation. As an English major, I love the opportunity to write 23 blog articles for the company’s e-commerce website and complete independent research into the company’s new product line. I learned how to use platforms that would benefit me in future roles, like WordPress, Hootesuite, and Canva. I also worked with my intern co-workers to develop a social media campaign derived from the company’s core cultural values.

Where Am I Now?

Ecolink gave me the valuable opportunity to gain experience in an office environment and get to know the world of digital marketing. I’ve since graduated from Oglethorpe University in May 2020 with a degree in English Literature, and a minor in Writing. I currently hold a part-time Marketing Content Writer position with Piedmont National, which wouldn’t have been possible without interning at Ecolink.

What Are Ink Solvents Ecolink

What Are Ink Solvents and their Components?

In the world of ink, you mainly have two choices: water-based ink or oil-based ink. The term ink solvent refers to the ink containing an oil-based solution. This ink is a relatively inexpensive type of ink that is compatible with inkjet printers. An attribute of solvent inks is that it is waterproof, thus making it resistant to fading and wearing. It is a common ink used to print on different uncoated banners and vinyls because the pigment bonds well with these materials. Normally, the solvent will evaporate or be flashed off with the heaters on the printer, which will leave only the pigment on the material.

Typically, ink solvent is used to print on outdoor products because of its ability to adhere to non-absorbent materials. This ink is excellent for use with long-term outdoor banners and vinyl because it is able to resist fading for five to seven years. However, venting is important for this ink because of the presence of volatile organic compounds.

Components 

  • The carrier fluid in this type of ink is an oil-based carrier, and it keeps the other components in liquid form.
  • Pigments produce color in solvent ink. Typically, pigments are applied in powder form in order to enhance the color quality.
  • Resin is the aspect of the ink that makes the color stick and protects it from damage. 

Maintenance

Regular cleanings are mandatory when using ink solvent in order to keep the printer running smoothly. The oil-based solution can be very corrosive because it does not take a lot of heat for the carrier to evaporate. If not cared for properly, the print head used with solvent ink will clog. Therefore, in order to prevent the need to purchase a new print head, the user should not let a solvent printer sit around for a few days without

Solvent and Eco-Solvent Ink Differences

Ink Solvent and Eco-Solvent Ink Differences

First, let us start off by explaining what eco-solvent ink is and some of its benefits. Eco-solvent ink is an oil-based ink, but what sets it apart from other solvent inks is that it is made from ether extracts taken from refined mineral oil. These inks are odorless due to the fact that their colors are suspended in a mild biodegradable solvent; therefore, they do not contain as many volatile organic compounds. However, before using eco-solvent ink you should consider the type of material you want to print on because these inks require more heat to dry than normal inks.

Benefits of eco-solvent printing

  • Lack of odor in printing area and printed material
  • Ink cartridges are not as harmful to your printing components
  • Easier maintenance

Solvent Ink versus Eco-Solvent Ink

There is no denying the many benefits of using eco-solvent inks; however, it is important to consider the type of printing you would like to do before choosing the solvent. As previously mentioned, eco-solvent ink is not a great choice for all types of materials because of the amount of heat required to dry it. If you are printing on a thin vinyl material, then solvent ink would be a better choice. In regard to costs, eco-solvent inks are more expensive than solvent inks. However, they are usually used by those who have medium-sized printing needs, such as a business or individual that is just starting out. While on the other hand, industrial printing, or large-scale printing, is still typically done with solvent inks. Another important aspect to consider when choosing which type of ink to use is the compatibility with your printer because only some printers are able to function properly with eco-solvent ink.
