What is ethyl lactate used for?
Ethyl Lactate is a colorless liquid with a mild odor. It is used as a solvent for dyes, lacquers, paints, enamels, nitrocellulose, cellulose ethers, and resins, in the manufacture of safety glass and stencil paper, and as an additive for food and cosmetics.
Is ethyl lactate an alcoholic?
It is a secondary alcohol, a lactate ester and an ethyl ester. It derives from a 2-hydroxypropanoic acid.
Why is ethyl lactate a good solvent?
As compared to ethanol, methanol, acetone, ethyl acetate and hexane, ethyl lactate is a suitable alternative solvent because it has low toxicity, volatility and flammability, thus creating a safer working environment to extract phytonutrients from food wastes industrially.
Where can ethyl lactate be found?
Ethyl lactate is found naturally in small quantities in a wide variety of foods including wine, chicken, and various fruits. The odor of ethyl lactate when dilute is mild, buttery, creamy, with hints of fruit and coconut.
How do you make ethyl lactate?
The conventional way to produce ethyl lactate is in a batch reactor, where the esterification reaction between ethanol (usually in excess) and lactic acid is carried out until equilibrium; then the equilibrium mixture is fed to various separation units (mainly energy intensive distillation steps) in order to recover …
Is ethyl lactate a VOC?
Additionally, ethyl lactate is not an ozone depleter, is biodegradable, and is not a volatile organic compound (VOC).
Is ethyl lactate a renewable feedstock?
Ethyl lactate is a nontoxic and biodegradable solvent derived from renewable carbohydrates. Its use and acceptance can be increased only if it is competitively priced to replace traditional organic solvents such as methylene chloride and chloroform.
What can be used instead of ethyl acetate?
Acetone can be used in place of ethyl acetate for compounds that show adsorption at wavelengths below 220 nm and are not UV active at 254 nm. Acetone is a cheaper alternative to ethyl acetate.
Is ethyl lactate a green solvent?
Ethyl lactate is a green, and economically viable, alternative to traditional solvents whose extensive use and scale-up to industrial level requires a deep and accurate knowledge of its properties in wide pressure–temperature ranges.
Is ethyl lactate biodegradable?
Unlike the conventional solvents, ethyl lactate is highly biodegradable. “In a fifty-fifty mix with water, it starts to break down in just five days,” says Bergmann. The breakdown products are carbon dioxide and water.
How is ethyl lactate used in organic synthesis?
Ethyl lactate is an economically viable green solvent used in organic synthesis. It is generally employed in organic reactions like multi-component reactions, cycloaddition reaction, asymmetric induction, photochemical synthesis, and ligand-free coupling reactions, etc.
What does the odor of ethyl lactate smell like?
The odor of ethyl lactate when dilute is mild, buttery, creamy, with hints of fruit and coconut. Ethyl lactate is produced from biological sources, and can be either the levo ( S) form or dextro ( R) form, depending on the organism that is the source of the lactic acid.
What foods are a good source of ethyl lactate?
Ethyl lactate. This compound is considered biodegradable and can be used as a water-rinsible degreaser. Ethyl lactate is found naturally in small quantities in a wide variety of foods including wine, chicken, and various fruits. The odor of ethyl lactate when dilute is mild, buttery, creamy, with hints of fruit and coconut .
How much ethyl lactate is soluble in water?
1000 mg/mL at 20 °C miscible with water; soluble in organic solvents, oils miscible (in ethanol) 1.03 at 68 °F (USCG, 1999) U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) – Hazardous Chemical Data. Commandant Instruction 16465.12C.
