Lab 9.
Safety.
Besides the regular safety rules, in this experiment you
should be aware of the following:
- a hazardous nature of the liquids you study: benzoyl
chloride - a potent lachrymator and possible
carcinogen, must be disposed properly; and solids: calcium
carbide
- Acetylene is
flammable; there should be no flames in the filling or
synthesis area which, if feasible, should be in a hood.
In its free state, acetylene may decompose violently; the
stability decreses at higher pressures but at pressures
below 1 atm the gas can be handled safely. WEAR SAFETY
GLASSES. Unalloyed copper, silver, and mercury should
never be used in direct contact with acetylene,
particularly when wet, owing to the possible formation of
explosive acetlides.
