Other large-volume esters are vinyl acetate [108-05-4] (VAM, 1.15 x 10 t/yr), methyl methacrylate [80-62-6] (MMA, 0.54 x 10 t/yr), and dioctyl phthalate [117-81-7] (DOP, 0.14 x 10 t/yr). VAM (see Vinyl polymers) is produced for the most part by the vapor-phase oxidative acetoxylation of ethylene. MMA (see Methacrylic polymers) and DOP (see Phthalic acids) are produced by direct esterification techniques involving methacryHc acid and phthaHc anhydride, respectively. 

Certain monobutyltin compounds have recently been introduced 561) as esterification catalysts, e.g., in the reaction of phthalic anhydride with octanol to produce dioctyl phthalate.

Note In the documented literature, bis(2-ethylhexyl) phthalate is sometimes referred to as dioctyl phthalate. Not to be confused with di-/ -octyl phthalate. Technical grades may contain minor quantities of acetic acid and phthalic anhydride.

Phthalic anhydride reacts with alcohols such as 2-ethylhexanol to form liquids that impart great flexibility when added to many plastics without hurting their strength. Most of these plasticizers, about 80%, are for poly(vinyl chloride) flexibility. Dioctyl phthalate (DOP), also called di-(2-ethylhexyOphthalate (DEHP), is a common plasticizer. 

Plasticizers such as dioctyl phthalate (51%), unsaturated polyester resins (24%), and alkyd resins (12%) account for the majority of phthalic anhydride use.

Phthalates. These esters, prepared from o-phthalic anhydride, constitute the most important group of plasticizers from the stand-point of production and sales volume. Among these the dioctyl phthalates are the most widely used in vinyl chloride resins, where they are preferred because they offer a good compromise with respect to a wide range of properties satisfactory volatility, good compatibility, fair low-temperature flexibility,... 

Phthalic anhydride is made by air oxidation of ortho-xylene. About half of phthalic anhydride is used to make plasticizers, especially the compound dioctyl phthalate, for softening polyvinyl chloride plastic. Phthalic anhydride is also used to make unsaturated polyester resins and alkyd paints.

For the esterification of terephthalic acid with ethylene glycol at 473 K, SO /TiCh calcined at 773 K is much more active than SiC -A Ch as shown in Fig. 6 [60]. The SO /TiCh showed a maximum activity when calcined at 573 K for the esterification of oleic acid with glycerol and of propionic acid with butanol at 403 K [61], where the active sites were attributed to Bronsted acid sites from a correlation between the activity and the Bronsted acidity. The esterification of phthalic anhydride with 2-ethylhexanol to form dioctyl phthalate is also efficiently catalyzed by solid super-acids, the selectivity being more than 90% [62]. The... 

EH is esterified with phthalic acid to produce the standard plasticizer dioctyl phthalate (DOP). With a capacity of roughly 5 million metric tons per year, n-butyraldehyde is among the most important applications of homogeneous catalysis [9,35]. 

The high thermal stability also has a significant influence on conversion rates in the esterification of phthalic anhydride with alcohols, e. g. 1-octanol or 2-ethylhexanol, to yield dioctyl phthalates. Product yields >99% for the diester are reported for residence times between 30 and 50 min and temperatures between 150 and 180 °C [15,17,18]. 

Phthalide (241) has been used as an additive used to prepare polyesters with low molten viscosity <91JAP(K)03200859>. Phthalic anhydride (242), prepared by the oxidation of o-xylene, is of major importance to the chemical industry with 1992 production over 400000 tonnes <93CEN38>. It is used as a monomer in the preparation of alkyd resins (a polyester with glycerol and other polyols) and thermosetting polymers (with maleic anhydride and polyols). Another important application is in the production of dioctyl phthalate (243), which is used as a plasticizer for PVC (1991 production, 123000 tonnes). Over 400 references pertaining to the use of phthalic anhydride in polymer compositions have appeared since 1982. Tetrabromophthalic anhydride (244) has been used to prepare flame-retardant bisphthalimides as polymer additives <90JAP(K)02145568>.

Many plasticizers are based on phthalic (or adipic) esters, the most common in use being dioctyl-phthalate (DOP). A large variety of plasticizers of many stmctural families is offered including blends. It is essential to have compatibility between polymer and plasticizer, in order to obtain homogeneity. One way of attaining compatibility is by adjusting solubility parameters. Phosphorous compounds function also as fire retardants. The performance of a plasticizer is measured by the intrinsic effect on flexibility (mainly at low temperature). But the total system stability should be considered, involving the elimination of eventual diffusion from the body to the atmosphere or side effects on polymer endurance in weather and fire.
