Di-n-butyl ether

CAS No. 142-96-1

Formula: C8H18O
Basic Info

Dibutyl ether is a chemical compound belonging to the ether family with the molecular formula of C 8H 18O. It is colorless, volatile, and flammable liquid and has peculiar ethereal smell.
Liquid dibutyl ether is lighter than water. On the other hand, the vapor is heavier than air. It is not soluble in water, but it is soluble in acetone and many other organic solvents. Due to this property, dibutyl ether is used as solvent in various chemical reactions and processes. For example, phenyllithium is commercially available as a ca. 1.8 M solution in dibutyl ether.
Because of the formation of peroxides, it should be protected from heat, light and air.

Inhalation causes irritation of nose and throat. Liquid irritates eyes and may irritate skin on prolonged contact. Ingestion causes irritation of mouth and stomach. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Ethers and related compounds/

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Dibutyl ether achieved 16% of its theoretical BOD in screening tests which utilized acclimated mixed microbial cultures over a 5 day incubation period(1). Many ethers are known to be resistant to biodegradation(2). Dibutyl ether at 100 mg/L reached 3 to 4% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(3).

12.3 Bioaccumulative potential

BCFs of 47 to 83 and 30 to 114 were measured for carp exposed to 200 and 20 ug/L of dibutyl ether over the course of a 6 week incubation period(1). According to a classification scheme(2), these BCFs suggest bioconcentration in aquatic organisms is moderate to high, provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for dibutyl ether can be estimated to be 51(SRC). According to a classification scheme(2), this estimated Koc value suggests that dibutyl ether is expected to have high mobility in soil(SRC).

12.5 Other adverse effects

no data available
