How do you identify resorcinol?
How do you identify resorcinol?
Resorcinol is a very white crystalline solid that becomes pink on exposure to light if not completely pure. Burns although ignition is difficult. Density approximately 1.28 g / cm3. Irritating to skin and eyes.
At what pH is resorcinol most soluble in water?
The water solubility data indicate that resorcinol is almost completely miscible in water. The pKa values of 9.32 and 9.81 (at 25 °C) indicate that resorcinol is present almost entirely in the protonated form under environmental conditions (pH 5–8).
Is resorcinol aliphatic or aromatic?
| Functional group | Aliphatic compound | Aromatic compound |
|---|---|---|
| Hydrocarbon | Methane, Acetylene, Cyclohexene | Benzene, Toulene, Napthalene |
| Alcohol | Methanol, Ethanol | Phenol |
| Poly hydrols | Glycerol, Glycol | Resorcinol |
| Ether | Diethyl ether | Ethoxy benzene |
How do you use resorcinol?
Apply enough resorcinol to cover the affected areas, and rub in gently. Immediately after using this medicine, wash your hands to remove any medicine that may be on them. Keep this medicine away from the eyes. If you should accidentally get some in your eyes, flush them thoroughly with water.
Why is resorcinol used in hair dye?
In permanent hair dyes, resorcinol reacts with a developer (usually peroxide)to bond the dye permanently to the hairs. Resorcinol is usually used with other chemicals to get a specific dye color. Resorcinol is used in acne and skin treatment medication to remove hard scaly or rough skin.
Is resorcinol acidic or basic?
Resorcinol has only -I effect and no counteracting electron-donating effects, which makes it the most acidic.
Does resorcinol give iodoform test?
No. The reason being that carboxylic acid and its derivatives do not give iodoform test. This is because due to resonance there is no free existence of C=O. group which is required for reaction.
How is resorcinol formed?
resorcinol, also called m-dihydroxybenzene, phenolic compound used in the manufacture of resins, plastics, dyes, medicine, and numerous other organic chemical compounds. It is produced in large quantities by sulfonating benzene with fuming sulfuric acid and fusing the resulting benzenedisulfonic acid with caustic soda.
What does resorcinol test for?
re·sor·ci·nol test a test for fructosuria; fresh urine treated with resorcinol in acid gives a red precipitate in the presence of fructose; the precipitate should form a red solution in ethanol. Synonym (s): Selivanoff test
What is the use of resorcinol monoacetate?
It is also used as compound resorcinol ointment, which contains 6% resorcinol. Resorcinol monoacetate gradually liberates resorcinol and, therefore, exerts a milder but more lasting action. It is used for the same purposes as resorcinol. Resorcinol monoacetate is compounded with sulfur in preparations for seborrhea.
How to detect free resorcinol in plasma and urine?
A high-performance liquid chromatography technique, requiring only a simple ethanol extraction, is described for the detection of free resorcinol in plasma and urine at concentrations as low as 0.5 mug/mL. The method gives recoveries of >90% with good reproducibility.
What does resorcin look like?
Resorcin is a crystalline solid very white and soluble in water, ether, and alcohol. It has a faint odour with sweetish to bitter taste. It does not dissolve carbon disulfide and chloroform. It turns into pink when to light if it is not in its pure form.
