High molecular weight biodegradable polyesters were prepared from sebacic acid, ethylene glycol and butylene glycol through a simple non-solvent polycondensation with a low toxicity catalyst. The successful synthesis of the polyesters was confirmed by gel permeation chromatography, (1)H-nuclear magnetic resonance and Fourier transform-infrared ...

Toxicology of a butylene glycol adipic acid polyester
Toxicology and Applied Pharmacology, 1973Abstract No adverse effects were encountered with a butylene glycol adipic acid polyester in chronic feeding studies in rats and dogs or in a 3-generation rat production study at dietary levels of 1000, 5000 and 10,000 ppm.

A method has been developed for the separation and measurement of ethylene glycol and three other glycols (propylene glycol, 1,3-butylene glycol and 2,3-butylene glycol) in biological samples by wide-bore column gas chromatography with a flame ionization detector. The method used 1,3-propylene glycol (1,3-propanediol) as an internal standard.

Cross-Reactivity between Propylene Glycol and Butylene Glycol
Dermatitis®Abstract: Background: Propylene glycol (PG) and butylene glycol (BG) are not known to be cross-reactors. However, no large-scale studies have assessed the cross-reactivity rate (CRR) between these 2 structurally and ...

The Present Status of the 2, 3-Butylene Glycol Fermentation
1963Publisher Summary This chapter explores the development on fermentation production of 2, 3-butylene glycol. The earliest report of the production of 2, 3-butylene glycol by bacterial fermentation was that of Harden and Walpole using cultures of Aerobucter aerogenes.

Preparation of radioactive diacetyl, acetoin, and 2,3-butylene glycol
Analytical Biochemistry, 1981Abstract Toluene-treated cells of Streptococcus diacetilactis produced large amounts of diacetyl and acetoin without 2,3-butylene glycol. With Na-[3-14C]pyruvate added to reaction mixtures in place of unlabeled pyruvate, diacetyl with specific activity of 6.1 × 104 cpm/μmol and acetoin with specific activity of 6.8 × 104 cpm/μmol were harvested ...
