Citric acid esters are used as plasticizers ia plastics such as poly(viayl chloride), poly(vinhdene chloride), poly(viQyl acetate), poly(viQyl butyral), polypropylene, chlorinated rubber, ethylceUulose, and cellulose nitrate. Most citrate esters are nontoxic and are acceptable by the FDA for use in food-contact packaging and for flavor in certain foods. As a plasticizer, citrate esters provide good heat and light stabiUty and excellent flexibiUty at low temperatures. Triethyl citrate, tri- -butyl citrate, isopropyl citrate, and stearyl citrate are considered GRAS for use as food ingredients (224—228). 

It is evident that, in order to obtain accurate results, the method of working must be clearly and minutely adhered to, especially so in view of the fact that the determination of ester by the method of steam distillation is a very valuable indication as to the purity of an oil, serving to detect the fraudulent addition to oils of such esters as diethyl succinate, triethyl citrate, and diethyl oxalate, the free acids of which are nonvolatile in steam. It will not detect glyceryl acetate, terpinyl acetate, nor the esters of coconut oil fatty acids. 

Polyvinyl acetate phthalate (PYAP) dissolves at pH higher than 5 and is soluble in ethanol. Plasticizers that are used with PVAP include triethyl citrate, glyceryl triacetate, and acetyltriethyl citrate. 

Hydroxypropyl methylcellulose acetate succinate (HPMCAS) dissolves at pH higher than 5, and there are three kinds of HPMCAS—AS-LG, AS-MG, and AS-HG. Triethyl citrate is a common plasticizer used with HPMCAS. 

Bergamot oil is adulterated in various ways, e.g., with oil of turpentine, oil or terpenes of lemon, orange terpenes, fatty oils, waxes, resin, gurjun and Canada balsam, cedarwood oil, mineral oils, chlorinated compounds of oil of turpentine, organic acids, various esters (diethyl succinate, triethyl citrate, diethyl oxalate, terpinyl acetate, esters of oleic, phthalic, tartaric and acetic acids). Such adulteration is usually made judiciously, the genuine oil being treated with such quantities of one or more picked adulterants as will not alter too markedly the characters of the oil itself.1... 

Figure 5. Output from a ratiometric intensity analyzer designed to monitor oxygen using [(dppe)Pt S2C2(CH2CH2-A -2-pyridinium) ] [BPh4], immobilized in cellulose acetate plasticized with 75%/wt. triethyl citrate. [Adopted from (21).] The instrument response voltage correlates directly to the triplet/singlet ratio of the dual emitter at various oxygen concentration.

When immobilized in a polymer-plasticizer matrix, (dppe)Pt S2C2(2-py) (CH2CH2OH), can be used for the rapid selective detection of volatile fluoro-, chloro-, and cyanophosphates (Table III, Fig. 10). As with many film immobilized lumiphores, the reactivity is controlled by the immobilizing matrix (39-44, 46, 50-52, 57, 58, 63, 75-77) Such an effect is seen as the sensitivity to phosphate esters increases as plasticizer (triethyl citrate, TEC) concentration increases in the cellulose acetate CA/TEC film (Table IV). 

HNP, NICO, but a greatly reduced errosion coefficient (N2/CO) can be found (Tab. 4.11b, Fig. 4.4a). It is also worth mentioning that the HNP and NICO are similar in their performance to NILE (Navy Insensitive Low Erosion Propellant 40% RDX, 32% GUDN, 7% acetyl triethyl citrate, 14% cellulose acetate butyrate, 5% hydroxyl propylcellulose, 2 % plasticizer). 

Cellulose acetate is incompatible with strongly acidic or alkaline substances. Cellulose acetate is compatible with the following plasticizers diethyl phthalate, polyethylene glycol, triacetin, and triethyl citrate. 

Plasticizers are often included in polyvinyl acetate phthalate coating formulations to enable a continuous, homogeneous, noncracking film to be produced. Polyvinyl acetate phthalate has been shown to be compatible with several plasticizers such as glyceryl triacetate, triethyl citrate, acetyl triethylcitrate, diethyl phthalate and polyethylene glycol 400. 

Monoisopropyl citrate, stearyl citrate, triethyl citrate (TEC), butyl and octyl maleates, and fumarates are other important plasticizers for the preparation of stable PC pastes and of low-temperature-resistant PVC products. Triethyl citrate and triethyl acetyldtrate are among the few plasticizers to have good solvency for cellulose acetate. In comparison with diethyl phthalate, with which they are in competition in this application, there are slight but not serious differences in volatility and water sensitivity. The interest in citrate esters is due to a favorable assessment of their physiological properties. They are intended for plastic components used for packaging of food products.
