Dimethyl suberate

Methyl esters of dibasic carboxylic acids >dimethyl suberate (usually have a series of peaks at m/zs 84, 98, 112, 126, 140, etc.)... 

Dimethyl octanedioate (dimethyl suberate), 71.2 g (0.352 mol), 1,4-butanediol (5% excess 0.370 mol, 33.3 g), and 0.02 g of tetraisopropoxytitanium (0.025% of final polyester mass) are placed in a three-necked round-bottomed flask fitted with a mechanical stirrer. The medium is slowly heated to 150°C within 4 h under nitrogen atmosphere while methanol is distilled off. Vacuum is then slowly applied and the reaction continued at 0.01 mbar and 150°C for 48 h. The resulting polyester is cooled down, dissolved in chloroform (50 g polyester/200 mL chloroform), and slowly added to a 10-fold volume of methanol under high-speed agitation (1000 rpm). The precipitated polyester is filtered off and dried at 30°C under vacuum (0.1 mbar).
