A risk of explosion exist.

∙ 16y agoUpon heating, the organic compound will vaporize (that is the point in a distillation after all), and therefore the pressure inside the apparatus will build. If it is tightly sealed, the pressure will build until the whole things breaks and then explodes. That's never good. Usually distillation is done either open to air, or if the compound is air or water sensitive, the distillation is done under nitrogen or argon gas with a oil bubbler used as a one-way valve -- gas from inside the apparatus can escape, but no air from the surrounding can enter.

∙ 14y agoIt is dangerous due to gasses from the mixture causing the pressure of the system to increase (as gasses take up more volume than liquids).This pressure build up could cause the glass to shatter.
Wiki User
∙ 12y agoLiquid (water) has a definite volume while gas does not. As the distillation continues and more vapor is released it causes the pressure in the apparatus to rise, without a release of the pressure the apparatus will explode and shatter.
Wiki User
∙ 11y agoAs the temperature increases and the solution starts boiling, converting from a liquid to a gas, the gas pressure increases. In an enclosed apparatus, this would cause the apparatus to break, releasing hot gas and liquid into the area, possibly causing injury.

∙ 14y agoWhen the temperature inside a tightly sealed apparatus is heated, the pressure inside increases. It will explode!
Wiki User
∙ 8y agoIt not only dangerous because of pressure built-up by boiling fluids but also impossible: distillation is built on the priciple of evaporation of fluids at normal or even lower pressure.
Wiki User
∙ 7y agoBecause the pressure of the gasses inside will increase and may shatter the apparatus.
Wiki User
∙ 7y agoHeating in a closed vessel will cause an increase in pressure, and ultimately, an explosion. If open to the atmosphere, no increase in pressure will occur.

Why are bottle of chemicals kept tightly closed except when a quantity of chemical is being removed?
Some chemicals react with the air, or are volatile and would escape. Others might be dangerous if the bottle falls over and the chemical spills out.
What are tightly and loosely coupled multiprocessor systems?
smp is tightly coupled ad cmp is loosly coupled
What are the major difference between a gas and solids or liquids?
solids - tightly packed and unable to move liquids- tightly packed but able move gases- spread out and able to move
A state of matter that contains particles that are tightly linked together in a definite shape?
In SOLIDS, molecules are most tightly bonded together.
Which state of matter are atoms most tightly packed?
Solid !
Why must the chromatography chamber be closed tightly?
so that the atmosphere in the jar becomes saturated with solvent.
What happens to the particles in a liquid when it's vaporized?
the particles are less tightly packed so are free to go into the atmosphere... did u do gcse science
Does a fungus decay faster when sealed tightly in a jar or just leaving it outside without any jar?
Outside exposed to the atmosphere. Needs Oxygen to decompose
What is the comparative and superlative form of tightly?
more tightly, most tightly
Why must a container be sealed in distillation?
Short answer: Distillation heats a liquid mixture and then cools the vapor that boils off to recover the more volatile portion of the original mixture. If you have a leaky apparatus you can lose a lot of this volatile portion because it will leak into the atmosphere before it has a chance to condense into your receiving vessel. This wastes energy and can create a fire or explosion hazard if you are distilling flammable liquids. It will create health or environmental problems if you are working with toxic materials or materials that are harmful to the environment. Long answer: Distillation works by either heating a liquid to produce vapor or reducing the pressure over a liquid to make it boil into a vapor at a lower temperatures. The vapor must be condensed by cooling to recover the "distallate" product you are after. With heated distillation you will lose much of the vapor through before you can condense it if you have a leaky apparatus. This is especially true if the distillation occurs at high pressures. For vacuum distillation you may not be able to create enough vacuum to cause the liquid mixture to boil if there are any large leaks or you will waste a lot of power creating the needed vacuum pressure in a leaky distillation column.
What part of speech is tightly?
Tightly is an adverb.
Is tightly an adjective?
nope, it is an adverb. It is describing the verb. Ex: tightly touched tightly held
Is tightly an action verb?
No tightly not an action verb
Is liquid dangerous?
It is extremely dangerous, it can cause rapid freezing if it comes into contact with living tissue (skin). Also, if you put it in a closed container (like a Thermos bottle with the top screwed on tightly) that isn't strong enough to handle the buildup of pressure, it can actually cause the container to explode.
When was Tightly Unwound created?
Tightly Unwound was created in 2007.
