오소포름산에틸 MSDS


Ethyl orthoformate

오소포름산에틸 C화학적 특성, 용도, 생산

화학적 성질

Colorless liquid; pungent odor. Highly flammable. Slightly soluble in water; soluble in alcohol, ether; decomposes in water.

용도

Labelled Prednisolone 21-Sulfate (P703755). Prednisolone 21-Sulfate is a metabolite of Prednisolone (P703740).

용도

A reagent useful for acetylization and imidic ester formation.

일반 설명

A clear, colorless liquid with a pungent odor. Less dense than water. Flash point 86°F. Vapors heavier than air. May irritate skin and eyes. Used to make other chemicals.

반응 프로필

Triethyl orthoformate 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.

위험도

Flammable, moderate fire risk.

건강위험

May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

화재위험

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.

Safety Profile

Moderately toxic by ingestion. Mddly toxic by inhalation, skin contact, and subcutaneous routes. A skin and eye irritant. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidzing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

Purification Methods

Fractionate it first at atmospheric pressure, then in a vacuum. If impure, then shake it with aqueous 2% NaOH, dry it with solid KOH and distil it from sodium through a 20cm Vigreux column (p 11). Alternatively, wash it with H2O, dry it over anhydrous K2CO3, filter and fractionate it through a Widmer column (p 11).
