Tetraethylene glycol di-

A base-promoted reaction between L-threitol and tetraethylene glycol di-tosylate afforded (165) the chiral bis(15-ctown-5) derivative l-146 as well as the trans-fused bicyclic system l-147 containing 15-crown-5 and 17-crown-5 rings. These constitutional isomers, which were separated chromatographically, were characterized by preparing l-147 unequivocally by a stepwise route from 2,3-O-isopropylidene-L-threitol. [Pg.259]

Acridine-4,5-diol was converted to the corresponding 18-crown-6 ligand by alkylation of the hydroxy groups with tetraethylene glycol di-p-tosylate <99T1491>. [Pg.251]

Packaging film from plasticized PVCD has improved thermal stability and reduced stickiness to metal surfaces when only 2 wt% of epoxidized soybean oil is added as a plasticizer. In addition, the metal soaps of ricinoleie acid are added. They also act as plasticiz-ers. The addition of 1 to 4 wt% tetraethylene glycol di-(2-ethylhexoate) is expected to reduce oxygen transmission rates and to improve extrudability of film. ... [Pg.346]

PVB is plasticized for specific applications. Saflex contains 32 phr (parts per hundred resin) of di-n-hexyl adipate. Butacite is PVB plasticized with 38.5 phr tetraethylene glycol di-M-heptanoate. [Pg.910]
