Octyl diesters

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. 

Alcohols can be phosphorylated to phosphoric diesters by ionic phosphoric monoimidazolides in acetone at temperatures of about 50-60 °C over the course of several hours. These imidazolides are generally prepared by reaction of the appropriate phosphate with CDI (see Section 2.2). Reactions with ethyl, -butyl, w-pentyl, -octyl benzyl alcohol and various other alcohols have also been described.[1]... 

An example of a solvent-dependent change in regioselectivity is the lipase-catalysed partial transesterification of the diester derived from 2-octyl-1,4-... 

The high thermal stability of the Deloxan ASP catalysts is also a key factor when looking at the achieved conversion rates in the esterification of phthalic anhydride with various alcohols, e.g. 1-octanol or 2-ethyl-hexanol, to yield di-octyl-phthalates (reaction 1) that are used as plasticizers. Product yields of > 99% for the diester are obtained for residence times between 30-50 minutes, at temperatures between 150°C and 180°C. 

O-methyl- and -octyl )S-D-glucopyranoside (7a and 7b, respectively) with ethyl butanoate without drying gave mainly the 6-O-acylated products 8, as would be expected, but with zeolite present complete conversion to the diesters took place. The 3,6-diesters 9 were mainly formed, together with the 2,6-isomers (10), depending on the size of the anomeric substituent.

The most common externally plasticized polymer is poly(vinyl chloride) (PVC) (—CH2CHCI ). A typical plasticizer for PVC is dioctyl phthalate (DOP), the diester of phthalic acid and wo-octyl alcohol note DOP is the more common term in industry, but the lUPAC name for this chemical is di(2-ethyl hexyl) phthalate or DEHP) ...
