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

SECTION 10: Stability and reactivity

10.1Reactivity

The substance can presumably form explosive peroxides. Reacts with strong oxidants.

10.2Chemical stability

no data available

10.3Possibility of hazardous reactions

Combustible when exposed to heat or flame; can react with oxidizing materials.DIETHYLENE GLYCOL MONOBUTYL ETHER is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

12.2Persistence and degradability

AEROBIC: Diethylene glycol mono-n-butyl ether had a 5 day BOD and COD of 0.25 and 2.08 g/g, respectively, this calculates to respective theoretical BOD and COD of 11 and 95%(1). Diethylene glycol mono-n-butyl ether showed losses of 2, 13, and 47% of the theoretical BOD when incubated at 20 deg C for 5, 10, and 20 days, respectively(2). Diethylene glycol mono-n-butyl ether degraded 14, 19, 60, and 100% when incubated for 1, 3, 5, and 6 days, respectively, using a non-adapted activated sludge and a modified Zahn-Wellens test(3). Another modified Zahn-Wellens test using non-adapted activated sludge gave 100% degradation after 9 days(3). Diethylene glycol mono-n-butyl ether showed 58 and >60% removal after 28 days using adapted activated sludge(3). In another screening study, diethylene glycol mono-n-butyl ether showed losses of 27, 60, 78, and 81% when incubated at 20 deg C for 5, 10, 15, and 20 days, respectively(4). Using the OECD 301D screening test, diethylene glycol mono-n-butyl ether showed losses of 3, 70, and 88% when incubated at 20 deg C for 5, 15, and 28 days, respectively(4). Using the OECD 301A method diethylene glycol mono-n-butyl ether showed a 94% removal after 14 days(3). Diethylene glycol mono-n-butyl ether had 5, 10, and 15 day BODs of 5.2, 57, and 72% of theoretical BOD(3). Diethylene glycol mono-n-butyl ether, present at 100 mg/L, reached 92% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5). A study using activated sludge gave a degradation rate for diethylene glycol mono-n-butyl ether of 0.37/hour(6) giving a half-life of about 1.9 hours(SRC).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for diethylene glycol mono-n-butyl ether(SRC), using a log Kow of 0.56(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of diethylene glycol mono-n-butyl ether can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylene glycol mono-n-butyl ether is expected to have very high mobility in soil.

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
