카테콜 C화학적 특성, 용도, 생산

화학적 성질

Off-white powder

용도

Catechol is used in photography, in dyeing fur, and as a topical antiseptic.

생산 방법

Catechol may be obtained by the fusion of o-phenolsulfonic acid with alkali, by heating chorophenol with a solution of sodium hydroxide at 200°C in an autoclave, or by cleavage of the methyl ether group of guaiacol (obtained from beechwood tar) with hydriodic acid.

정의

A colourless crystalline PHENOL containing two hydroxyl groups. It is used in photographic developing.

일반 설명

Solid; white; odorless. Sinks and mixes with water.

공기와 물의 반응

Turns brown on exposure to air and light, especially when moist. Water soluble. Aqueous solutions soon turn brown on exposure to air and light.

반응 프로필

POISONOUS GASES MAY BE PRODUCED WHEN HEATED. Pyrocatechol may form toxic fumes at high temperatures. [USCG, 1999]. Pyrocatechol can react with acid chlorides, acid anhydrides, bases and oxidizing agents. Pyrocatechol reacts violently on contact with concentrated nitric acid. Pyrocatechol acts as a reducing agent .

위험도

Strong irritant. Toxic by skin absorption. Eye and upper respiratory tract irritant, and der- matitis. Possible carcinogen.

건강위험

Acute oral and percutaneous toxicity of pyrocatechol is greater than that of phenol; inhalation toxicity is less than that of phenol. The toxic symptoms include weakness, muscular pain, dark urine, tremor, dyspnea, and convulsions. Large amounts can produce degenerative changes in renal tubules. Large doses can cause death due to respiratory failure. Skin contact can cause eczematous dermatitis.
LD50 value, oral (rats): 260 mg/kg
LD50 value, skin (rabbits): 800 mg/kg.

화재위험

Combustible. POISONOUS GASES MAY BE PRODUCED WHEN HEATED. May form toxic fumes at high temperatures.

Safety Profile

Poison by ingestion, subcutaneous, intraperitoneal, intravenous, and parenteral routes. Moderately toxic by skin contact. Experimental reproductive effects. Can cause dermatitis on skin contact. An allergen. Human mutation data reported. Questionable carcinogen. Systemic effects sirmlar to those of phenol. Combustible when exposed to heat or flame; can react vigorously with oxidizing materials. Hypergolic reaction with concentrated nitric acid. To fight fire, use water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also PHENOL.

잠재적 노출

Used as a chemical intermediate; pharmaceutical and veterinary drug; as an antiseptic; in photography; in dyestuff manufacture and application. It is also used in electroplating, in the formulation of specialty inks; in antioxidants; and light stabilizers.

Carcinogenicity

Catechol has been extensively studied for its role in carcinogenesis of the rat glandular stomach; it was concluded that pyrocatechol is carcinogenic. When rats and mice were administered 0.8% pyrocatechol in their feed for life, there was an increase in glandular stomach adenocarcinoma in both male and female rats. Pyrocatechol also caused hyperplasia of the glandular stomach in both rats and mice, a mechanism that could cause promotion of carcinogen-initiated cells; no effects on the esophagus or urinary bladder were reported. There were no cutaneous neoplasms when pyrocatechol was applied in dermal studies. Catechol may be classified as a cocarcinogen because it enhanced the number and/or incidence of lesions in the stomach induced by several carcinogenic nitrosamines and cutaneous neoplasms when administered dermally together with several carcinogens.

운송 방법

UN 2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Crystallise catechol from *benzene or toluene and sublime it in vacuo. [Rozo et al. Anal Chem 58 2988 1986, Beilstein 6 IV 5557.]

비 호환성

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
