Resorcinol is available in concentrations ranging from 2 - 50%. Resorcinol in concentrations greater than 10% is most effective, but also comes with more severe side effects. Over-the-counter resorcinol products, which contain up to 2% resorcinol, present fewer side effects than those containing higher concentrations and can be used daily. 2. Resorcinol is a white crystalline solid that turns pink upon exposure to light if not completely pure. The substance is flammable, although ignition is difficult. It is slightly toxic and is used to make plastics and as a chemical intermediate for the synthesis of pharmaceuticals and other organic compounds.

Scientists and researchers around the world working in the areas of pharmaceuticals, rubber compounds (tires, hoses, belts), polymers, polymer additives (UV absorbers, flame retardants), composites (polymers and wood Cited by: Resorcinol chemistry has been providing valuable properties and products in the development of advanced technologies in the areas of pharmaceuticals, rubber compounds, wood composites and plastics.
Notable technologies include steel belted radial tires, resorcinol-formaldehyde-latex adhesives (RFL), a weather proof polycarbonate (Sollx), a super heat resistant polymer (PEN.
A solution of resorcinol (11 g) in sodium hydroxide solution ( g of sodium hydroxide in 20 ml of water) is hydrogenated in the presence of g of 5% rhodium on alumina for 16–18 hours at 50 psi initial pressure in a Parr apparatus.
The reduction stops after the absorption of 1 equivalent of hydrogen. The catalyst is removed by filtration through celite, and the aqueous solution is. 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.
The chemistry, manufacture, and uses of the specialty chemical resorcinol (1,3-dihy droxybenzene) have a rich history, variety, and current interest.

Resorcinol, also called m-dihydroxybenzene, phenolic compound used in the manufacture of resins, plastics, dyes, medicine, and numerous other organic chemical is produced in large quantities by sulfonating benzene with fuming sulfuric acid and fusing the resulting benzenedisulfonic acid with caustic soda.
Reaction with formaldehyde produces resins used to make rayon and nylon. Resorcinol works by breaking down rough, scaly, or hardened skin. Resorcinol also disinfects the skin to help fight infection.
Resorcinol topical (for the skin) is used to treat pain and itching caused by minor cuts and scrapes, burns, insect bites, poison ivy, sunburn, or other skin inol topical is also used to treat acne, eczema, psoriasis, seborrhea, corns, calluses. Pizzi, C.C. Ibeh, in Handbook of Thermoset Plastics (Third Edition), Resorcinol Adhesives.
Resorcinol –formaldehyde (RF) and phenol–resorcinol–formaldehyde (PRF) cold-setting adhesives are used primarily in the manufacture of structural, exterior-grade glulam, finger joints, and other exterior timber structures.
They produce bonds not only of high strength, but also of. Resorcinol Glue. For most amateur boatbuilders Resorcinol is an echo from the past. They might have heard it mentioned in an old book, or some crusty woodworker might have raved about it.
Resorcinol is used to produce dehyde (RF) resin to improve the adhesion of rubber and other materials in rubber products, wood adhesives, flame retardants, UV stabilizers, dyes, and others. Approximately 50% of resorcinol is used in rubber products.
The other major uses are as a UV stabilizer and wood adhesive. Resorcinol is made by hydrogenating dinitrobenzene in an aromatic mono-nuclear hydrocarbon-lower alcohol mixed solvent system in the presence of a nickel catalyst at moderate temperatures and pressures.
Meta-phenylenediamine thus produced is hydrolyzed using aqueous sulfuric acid. Meta-phenylenediamine and sulfuric acid, moles per mole of metaphenylenediamine, are contacted.
Resorcinol, which was formerly used to treat leg ulcers, is nowadays mainly used in the treatment of acne vulgaris as a peeling agent .It is also used as a coupler in hair dyes. In the older literature , several cases of systemic toxicity from percutaneous absorption were reported and there were deaths .Signs and symptoms of resorcinol intoxication include.
Resorcinol is used to treat acne, seborrheic dermatitis, eczema, psoriasis, and other skin disorders. It is also used to treat corns, calluses, and warts. Resorcinol works by helping to remove hard, scaly, or roughened skin. Resorcinol, also known as m-dihydroxybenzene, is a phenolic compound which is used in the manufacture of resins, colorants, plastics, medicinal goods and many other organic chemical compounds.
It is formed in large amounts by sulfonizing benzene with fuming sulfuric acid and by fusing caustic soda to the resulting benzenedisulfonic acid.
Overall, resorcinol–formaldehyde organic gels undergo two main stages during synthesis. The first stage is associated with the preparation of the sol mixture, and the subsequent gelation and curing of the gel.
The second stage is associated with the drying of the wet gel. The most important factors that affect the properties of the organic. Book January Resorcinol in anti-acne preparations is usually 2%.
Anti-acne creams are likely to be used twice a day for an unlimited period, and the preparation.Resorcinol is obtained from its disodium salt after neutralizing the excess NaOH in the aqueous solution of the melt.
In addition to the Na 2 SO 3 from the actual reaction, Na 2 SO 4 is formed by acidification with H 2 SO 4. The crude resorcinol is extracted from the acidified aqueous solution with and purified by vacuum distillation.Resorcinol has been known to cause hyperemia (an excess of blood in a part), itch, dermatitis, edema, and corrosion.
Ingestion: May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause.
