6.2.3 Optimizationdistillation

Dependingonthesolventinvolved,itmayalsobepossibletofurtheroptimizethedis

tillationprocess.Thedistillationshouldalwaysbesetupsothatthecondensatedoes

notcovermorethanthreequartersofthecoilinthecondenser.Thetopquartershould

remainexposed.

WARNING

Riskofexplosionfromexcessiveinternalpressure

Theevaporatingflaskand/orthecondensercouldexplodeiftheinternalpressurepro

ducedbyevaporationbecomestoogreat.

u Makesurethattheinternalpressureinsidetheglasscomponentsisnevergreater

thanatmosphericpressure.

Ifthecondensationisbelow3/4ofthecondenser:

u increasethevacuum.

Thatwilllowertheboilingpointandmorevaporwillenterthecondenser.

u Inapplicationswherenovacuumisapplied,raisethetemperatureoftheheating

bathifnecessary.

Thatwillcausemoresolventtoevaporate.

Ifthecondensationisabove3/4ofthecondenser:

u decreasethevacuum.

Thatwillraisetheboilingpointandlessvaporwillenterthecondenser.
