Zusammenfassung:The present specification discloses a composition comprising a plurality of diols which is useful for the production of polyester bottles, wherein the diols are mainly obtained from the conversion of a ligno-cellulosic biomass feedstock stream. The composition comprises ethylene glycol and at least one diol selected from the group of diols having a formula of CH(OH)2, wherein n is the total number of carbons and is an integer in the range from 3 to 20, z is an integer in the range from 0 to 2n, and C1 and C2 are each attached to one of the OH groups of the formula (e.g. 1,2-Propylene glycol, 1,2-Butanediol and 1,2-Pentanediol) and wherein the composition is substantially free of diols which absorb light at a wavelength of 275 nm, so that the percent light transmission of the composition at a wavelength of 275 nm is greater than 40%.
