PRODUCT
Ethyllithium (ETLi), typ. 8 % solution in Dibutyl Ether (typ. 1.7 M)
Product No. 401700
CAS-No. 811-49-4
EINECS-No. 212-370-2
FURTHER
INGREDIENTS
Dibutyl Ether
CAS-No. 142-96-1 EINECS-No. 205-575-3
APPLICATION
Ethylating agent; strong organometallic base.
APPEARANCE
Colorless to yellowish solution
FORMULA
C 2 H 5 Li
PHYSICAL
PROPERTIES
Molecular weight:
36.00 g /mol
Density:
abt. 0.76 g/ccm (at 20°C)
Boiling Point:
141 °C for Dibuthyl Ether
Flash Point:
25 °C for Dibuthyl Ether
Thermal Stability:
No crystallization expected when stored at low temperature (-10 °C).
Stability:
Ethyllithium is known to cleave ethers. Nevertheless, the solution in dibutyl ether shows
sufficient stability to be used on an industrial scale.
Decomposition rates:
at 20 °C: abt. 0.25 % loss of active base / day
at 30 °C: abt. 0.75 % loss of active base / day
at 40 °C: abt. 2.50 % loss of active base / day
SPECIFICATION
Ethyllithium: 7 - 9 % (active base)
Active base: total base minus free base

ANALYSIS
Total base: titration of base after hydrolysis of ethyllithium
Free base: reaction of ethyllithium with benzylchloride; hydrolysis and titration of residual
base
HANDLING
Keep away from sources of ignition. Take precautionary measures against static discharges.
Handling only under inert gas (nitrogen or argon). Product is spontaneously flammable in air.
Pay attention to official safety regulations (see also: “Transport regulations” and “Marking“).
STORAGE
Keep container tightly closed in a cold-storage depot or refrigerator, if intended to be stored
for longer periods (see: “Decompositions rate”). Crystallization is not expected when stored
at low temperatures (-10 °C).
