Phthalate, di-iso-octyl

Di-(2-ethylhexyl)phthalate ( di-iso-octyl phthalate) [117-81-7] M 390.6, b 384°, 256-257°/lmni, d 0.9803, n 1.4863. Washed with Na2C03 soln, then shaken with water. After the resulting emulsion had been broken by adding ether, the ethereal soln was washed twice with water, dried (CaCl2), and evaporated. The residual liquid was distd several times under reduced pressure, then stored in a vacuum desiccator over P2O5 [French and Singer J Chem Soc 1424 1956]... 

Plasticised amorphous thermoplastics Certain plastics may be mixed with high-boiling low-volatility liquids to give products of lower T. The most important example occurs with p.v.c. which is often mixed with liquids such as di-iso-octyl phthalate, tritolyl phosphate or other diesters to bring the below room temperature. The resultant plasticised p.v.c. is flexible and to some degree quite rubbery. Other commonly plasticised materials are cellulose acetate and cellulose nitrate.

It was discovered in the twenties by Dr Waldo Semon when attempts were being made to dissolve PVC that it could be plasticized to give elastomer-like compounds, and since then an extensive variety of plasticizers has been suggested and many introduced commercially. The addition of plasticizers provides materials with a considerable range of flexibility and softness those used most commonly today are esters of C8 to C10 alcohols, such as phthalates, phosphates, and sebacates—particularly dioctyl phtha-late (known also as 2-ethylhexyl phthalate), di-iso-octyl phthalate, and dial-phanyl phthalate.

Ideally a plasticiser should maintain the flexibility of a polymer over as wide a temperature range as possible. In practice, a certain proportion of low temperature plasticisers such as sebacates or adipates is often added to the phthalate or other primary plasticiser to give optimum low temperature properties, although certain phthalates derived from straight chain alcohols are appreciably better than DOP (di-octyl phthalate) or DiOP (di-iso-octyl phthalate) in this respect.
