    Chemische Eigenschaften

    Acetyltriethyl citrate occurs as a clear, odorless, practically colorless oily liquid.

    Verwenden

    ATEC is produced by the reaction of citric acid triethyl ester with acetic acid anhydride. It is used as a solvent plasticizer for cellulose nitrate and cellulose acetate.

    Verwenden

    Triethyl O-Acetylcitrate is used in the preparation of poly(lactic) acid biodegradable and flexible films, acting as a plasticizer. Also used in the synthesis of control-release capsules containing polymeric coatings.

    Vorbereitung Methode

    Acetyltriethyl citrate is prepared by the esterification of citric acid with ethanol followed by acylation with acetic anhydride.

    Definition

    Aqueous-based pharmaceutical coat- ings.

    Allgemeine Beschreibung

    Certified pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Triethyl 2-acetylcitrate is widely used in hydrophilic adhesives for medications and in biodegradable composition for papermaking and nonwoven production.

    Pharmazeutische Anwendungen

    Acetyltriethyl citrate is used to plasticize polymers in formulated pharmaceutical coatings. The coating applications include capsules, tablets, beads and granules for taste masking, immediate release, sustained-release and enteric formulations. It is also used in diffusion-controlled release drug delivery systems.

    Sicherheit(Safety)

    Acetyltriethyl citrate is used in oral pharmaceutical formulations and is generally regarded as a nontoxic and nonirritating material. However, ingestion of large quantities may be harmful.
    LD50 (cat, oral): 8.5 g/kg
    LD50 (mouse, IP): 1.15 g/kg
    LD50 (rat, oral): 7 g/kg

    Lager

    Acetyltriethyl citrate should be stored in dry, closed containers at temperatures not exceeding 388℃. When stored in accordance with these conditions, acetyltriethyl citrate is a stable product.

    Inkompatibilit?ten

    Acetyltriethyl citrate is incompatible with strong alkalis and oxidizing materials.

    Regulatory Status

    Approved in the USA for direct food contact in food films.
