Description

1,2-Butanediol is a vic-diol (glycol) first described by Charles-Adolphe Wurtz in 1859. It is produced industrially as a byproduct of the production of 1,4-butanediol from butadiene, and is also a byproduct of the catalytic hydrocracking of starches and sugars such as sorbitol to ethylene glycol and propylene glycol.[note 2] It is used to produce polyester resins and plasticizers, and is a potential feedstock for the industrial production of α-ketobutyric acid, a precursor to many amino acids.

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

2-Butanol was shown to biologically oxidize to 1,2-butanediol in cell free extracts of Pseudomonas species(1). However, 1,2-butanediol was not converted using the same organism(1). Using an initial concn of 100 mg/L 1,4-butanediol, 74- 96 percent BOD was observed after a 2 week period in a biodegradation screening test using 30 mg/L sludge(2) and 1,2- butanediol is expected to behave similarly under the same conditions based on structural analogy to 1,4-butanediol(SRC).

12.3 Bioaccumulative potential

Based on an estimated log octanol-water partition coefficient of -0.29(2) and a recommended regression-derived equation(1), the BCF for 1,2-butanediol can be estimated to be 0.35(SRC). This BCF value indicates that 1,2-butanediol will not bioconcentrate in aquatic organisms(SRC).

12.4 Mobility in soil

Based on an estimated log octanol-water partition coefficient of -0.29(2) and a recommended regression-derived equation(1), the Koc for 1,2-butanediol can be estimated to be 17(SRC). According to a suggested classification scheme(3), this Koc value indicates that 1,2-butanediol will be very highly mobile in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
