1,5-Pentanediol is the organic compound with the formula HO(CH 2) 5 OH. Like other diols , this viscous colourless liquid is used as plasticizer and also forms polyesters that are used as emulsifying agents and resin intermediates.
1,5-Pentanediol, a common plasticizer and precursor to polyesters is manufactured by hydrogenation of glutaric acid and its derivatives. [3] Glutaric acid itself has been used in the production of polymers such as polyester polyols, polyamides. The odd number of carbon atoms (i.e. 5) is useful in decreasing polymer elasticity. [4]
1,3-Diols are described as syn or anti depending on the relative stereochemistries of the carbon atoms bearing the hydroxyl functional groups. Zincophorin is a natural product that contains both syn and anti 1,3-diols. Zincophorin depicting syn and anti-1,3-diol configurations
In general, the polyol synthesis begins with the heating of a polyol compound such as ethylene glycol, 1,5-pentanediol, or 1,2-propylene glycol7. An Ag + species and a capping agent are added (although the polyol itself is also often the capping agent).
