化学的特性

Ethyl lactate is a green solvent derived from processing corn. Ethyl lactate is the ester of lactic acid. Lactate esters solvents are commonly used solvents in the paints and coatings industry and have numerous attractive advantages including being 100% biodegradable, easy to recycle, noncorrosive, noncarcinogenic, and nonozone depleting.
Ethyl lactate is a particularly attractive solvent for the coatings industry as a result of its high solvency power, high boiling point, low vapor pressure, and low surface tension. Other applications of ethyl lactate include being an excellent cleaner for the polyurethane industry. Ethyl lactate has a high solvency power, which means it has the ability to dissolve a wide range of polyurethane resins. The excellent cleaning power of ethyl lactate also means it can be used to clean a variety of metal surfaces, effi ciently removing greases, oils, adhesives, and solid fuels. The use of ethyl lactate is highly variable as it has eliminated the use of chlorinated solvents.

化学的特性

Ethyl lactate has a light ethereal, buttery odor.

天然物の起源

Reported found in apple, apricot, grape, pineapple, raspberry, chicken, cocoa, plum, blackberry, cabbage, vinegar, rye and wheat bread, butter, beer, cognac, rum, whiskey, sherry, grape wines, fruit brandies and soy sauce.

使用

Ethyl lactate, for instance, is used in the electronics industry to remove salts and fat from circuit boards; it is also a component in paint strippers.

使用

As solvent for nitrocellulose and cellulose acetate.

使用

Ethyl Lactate is a solvent manufactured from l(+) lactic acid which is miscible in water and most organic solvents and is cleared for use as a flavoring agent. it is a naturally occurring constituent of california and spanish sherries. it is a clear, colorless, nontoxic liquid of low volatility, having a ph of 7–7.5. it is used as a food and beverage flavoring agent.

製造方法

d-Ethyl lactate is obtained from d-lactic acid by azeotropic distillation with ethyl alcohol or benzene in the presence of concentrated H2SO4; the l-form is prepared in a similar fashion starting from l-lactic acid; the racemic product is prepared by boiling for 24 hours optically inactive lactic acid with ethyl alcohol in carbon tetrachloride, or with an excess of ethyl alcohol in the presence of chlorosulfonic acid, or in the presence of benzenesulfonic acid in benzene solution.

調製方法

Ethyl lactate is produced by the esterification of lactic acid with ethanol in the presence of a little mineral oil, or by combination of acetaldehyde with hydrocyanic acid to form acetaldehyde cyanhydrin. This is followed by treatment with ethanol (95%) and hydrochloric or sulfuric acid. Purification is achieved using fractional distillation. The commercial product is a racemic mixture.

Aroma threshold values

Detection: 50 to 250 ppm

Taste threshold values

Taste characteristics at 50 ppm: sweet, fruity, creamy, and pineapplelike with a caramellic brown nuance.

一般的な説明

A clear colorless liquid with a mild odor. Flash point 115°F. Denser than water and soluble in water. Vapors heavier than air.

空気と水の反応

Flammable. Soluble in water.

反応プロフィール

Ethyl lactate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

危険性

Moderate fire risk.

健康ハザード

Inhalation of concentrated vapor may cause drowsiness. Contact with liquid causes mild irritation of eyes and (on prolonged contact) skin. Ingestion may cause narcosis.

火災危険

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

化学反応性

Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

応用例(製薬)

formulationsand recently as a co-solvent in emulsions and microemulsion technologies. It has also been used as a solvent for nitrocellulose, cellulose acetate, cellulose ethers, polyvinyl and other resins. It has been applied topically in the treatment of acne vulgaris,where it accumulates in the sebaceous glands and is hydrolyzed to ethanol and lactic acid, lowering the skin pH and exerting a bactericidal effect.

安全性

Ethyl lactate is used as a flavoring agent in pharmaceutical preparations, and is found in food products. The estimated acceptable daily intake for lactic acid is 12.5 mg/kg body-weight.
In general, lactate esters have an oral LD50 > 2000 mg/kg; and the inhalation LC50 is generally above 5000 mg/m3. They have the potential of causing eye and skin irritation (on prolonged contact), but not sensitization. Ethyl lactate is moderately toxic by intraperitoneal, subcutaneous, and intravenous routes. There is low oral and skin contact toxicity; although ingestion may cause nausea, stomach and throat pain, and narcosis. Inhalation of concentrated vapor of ethyl lactate may cause irritation of the mucous membranes, drowsiness, and narcosis.
LD50 (rat, oral): >5.0 g/kg
LD50 (mouse, oral): 2.5 g/kg
LD50 (mouse, SC): 2.5 g/kg
LD50 (mouse, IV): 0.6 g/kg
LD50 (rabbit, skin): >5.0 g/kg

Veterinary Drugs and Treatments

Ethyl lactate shampoo can be used when an antibacterial shampoo (bacteriostatic and bactericidal) is needed particularly in animals with surface and superficial pyodermas that cannot tolerate benzoyl peroxide. It also has keratoplastic effect, which provides anti-seborrheic activity.
A lipid soluble compound, ethyl lactate penetrates hair follicles and sebaceous glands where bacterial lipases convert it into lactic acid and ethanol, which are responsible for its antibacterial action. It is not as active as benzoyl peroxide against staphylococcal organisms, but is less irritating and drying.

貯蔵

Stable at normal temperature and pressure. Ethyl lactate is a flammable liquid and vapor. Store in a cool, dry, and well-ventilated location away from any fire hazard area, in a tightly closed container.

不和合性

Incompatible with bases or strong alkalis and may cause fire or explosion with strong oxidizing agents.

規制状況(Regulatory Status)

GRAS listed. Reported in the EPA TSCA Inventory.
