| | Triethyl acetyl citrate Usage And Synthesis |
| Chemical Properties | Acetyltriethyl citrate occurs as a clear, odorless, practically colorless
oily liquid. | | Uses | 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. | | Uses | 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. | | Production Methods | Acetyltriethyl citrate is prepared by the esterification of citric acid
with ethanol followed by acylation with acetic anhydride. | | Definition | Aqueous-based pharmaceutical coat-
ings.
| | General Description | 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. | | Pharmaceutical Applications | 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. | | 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 | | storage | 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. | | Incompatibilities | Acetyltriethyl citrate is incompatible with strong alkalis and
oxidizing materials. | | Regulatory Status | Approved in the USA for direct food contact in food films. |
