Background technology
Phenol (Phenol, C6H5OH) it is a kind of colourless acicular crystal with special odor, poisonous.Fusing point is 43 DEG C, often
It is slightly soluble in water under temperature, is soluble in organic solvent, when temperature is higher than 65 DEG C, can dissolve each other with arbitrary proportion with water.It is corrosive, connects
Can make local protein degeneration after touch, its solution is stained with on skin available ethanol wash.Phenol is a kind of laboratory common agents,
Owing to standing time is long, fraction phenol exposes in atmosphere and is oxidized by oxygen the pinkiness into quinone under light.
Phend-sulphuric acid is a kind of total sugar being widely used in laboratory and production or Methods in Determination of Polysaccaride Content, this
Method has the advantages such as simple to operate, quick, reproducible, highly sensitive, colour developing rear stability is preferable, and is not required to valuable instrument
Device, is first to be hydrolyzed into monosaccharide molecule under the effect of sulphuric acid according to polysaccharide, and monosaccharide molecule rapid dehydration generates alditol derivant, so
Become reddish violet compound afterwards with phenol condensation, at 490nm, have absorption maximum, then carry out the one of detection by quantitative with colorimetry
Conventional Methods in Determination of Polysaccaride Content, absorption value is linear with the content of sugar, and measurement result represents polysaccharide with monosaccharide
Content.
After phenol is oxidized, accuracy and repeatability to experimental result all have considerable influence, increase labor intensity, wave
A large amount of reagent and time are taken.When using phend-sulphuric acid to measure polyoses content, in order to ensure the purity of phenol, experiment is made to tie
Fruit accurately and reliably, therefore must carry out redistillation before using.During redistillation, due to weather reason, indoor temperature is relatively low, phenol
When fraction arrives condensing tube and adapter tube position, temperature is less than fusing point, the coagulation at condensing tube and adapter tube of phenol fraction, blocking
Outlet, meanwhile, constantly produces phenol fraction, makes internal pressure increase in alembic, pressure the most to a certain extent time, easily cause
Blast, can cause human body and burn, there is laboratory safety hidden danger.
