How do you make resorcinol solution?
A process for the preparation of resorcinol from diisopropylbenzene includes the steps of oxidizing m-diisopropylbenzene under anhydrous, non-alkaline conditions with oxygen, extracting m-diisopropylbenzene dihydroperoxide and m-diisopropylbenzene hydroxyhydroperoxide with dilute sodium hydroxide, re-extracting with an …
What is the formula of resorcinol?

Does resorcinol dissolve in ethanol?
Resorcinol disulfonic acid, (HO)2C6H2(HSO3)2, is a deliquescent mass obtained by the action of sulfuric acid on resorcin. It is readily soluble in water and ethanol.
How resorcinol is produced?
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.

At what pH is resorcinol most soluble in water?
pH 5–8
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 P-cresol an acid or base?
m-cresol is more acidic compared to p-cresol. This is completely true in water (the p-cresol is 10.3 and pKa of m-cresol is 10.1), and it is also completely true in the gas-phase with the difference in the acidity of ca 0.7 kcal/mol.
What is the formula for the compound resorcinol?
Resorcinol (or resorcin) is an organic compound with the formula C 6 H 4 (OH) 2. It is one of three isomeric benzenediols, the 1,3-isomer (or meta -isomer). It is a white, water-soluble solid. Resorcinol is produced in several steps from benzene, starting with dialkylation with propene to give 1,3-diisopropylbenzene.
What kind of Medicine is resorcinol used for?
Resorcinol is a 1,3-isomer (or meta-isomer) of benzenediol with the formula C6H4(OH)2. It is used as an antiseptic and disinfectant in topical pharmaceutical products in the treatment of skin disorders and infections such as acne, seborrheic dermatitis, eczema, psoriasis, corns, calluses, and warts.
How is resorcinol used in permanent hair coloring?
Resorcinol and 2-Methylresorcinol are used in permanent hair coloring systems where color is produced inside the hair fiber. This is accomplished through careful formulation of the product so that the ingredients interact in a highly controlled process.
Which is the meta isomer of resorcinol OH 2?
It is a benzenediol and a member of resorcinols. Resorcinol is a 1,3-isomer (or meta-isomer) of benzenediol with the formula C6H4 (OH)2. It is used as an antiseptic and disinfectant in topical pharmaceutical products in the treatment of skin disorders and infections such as acne, seborrheic dermatitis, eczema, psoriasis, corns, calluses, and warts.
