Triethyl citrate, the ester resulting from the esterification of citric acid with ethanol.

Physical Properties

The ester is a colorless liquid, boiling at atmospheric pressure at 294 ° C. The vapor pressure function is given by Antoine corresponding log10 (P) = A- ( B / ( T C)) (P in kPa, T in K) with A = 3.88263, B = 1743.204 and C = -122.435 in temperature range from 380 K to 567 K.

Use

Conventional plasticizers Phthalsäureesterbasis are discredited because of their health-and environmentally damaging aspects. Citric acid esters such as triethyl citrate here can be used as non-toxic alternative. It is used as an artificial carrier and stabilizer in food products, deodorants, polymers, and pesticides.

It is approved only for flavorings and egg white in the EU as a food additive called E 1505.
