요오드포름 C화학적 특성, 용도, 생산

개요

Iodoform is a stable, pale yellow crystalline solid. It is volatile with a characteristic pungent, unpleasant and penetrating odour, but with a sweetish taste. It is incompatible with strong oxidising agents, reducing agents, lithium, and metallic salts such as mercuric oxide, silver nitrate, strong bases, calomel, and tannin. Reports indicate that earlier iodoform was in use as a disinfectant and as an antiseptic or dressing and healing of wounds and sores for pets. Iodoform is the active ingredient in many antiseptic or dressing powders used for dogs and cats to prevent infection.

화학적 성질

Iodoform is a yellow or greenish-yellow powder or crystalline solid that is volatile with steam and contains 96.69% iodine. It has a very characteristic pungent odor. An odor threshold of 0.005 ppm has been reported.

용도

Iodoform has limited use as a chemical intermediate and for medicinal purposes as disinfectant and antiseptic and has been used in veterinary medicine.

정의

A yellow crystalline compound made by warming ethanal with an alkaline solution of an iodide:
CH₃CHO + 3I^– + 4OH^– → CHI₃ +
HCOO^– + 3H₂O
The reaction also occurs with all ketones of general formula CH₃COR (R is an alkyl group) and with secondary alcohols CH₃CH(OH)R. Iodoform is used as a test for such reactions (the iodoform reaction).

일반 설명

Bright yellow or yellow powder or crystals. Penetrating odor. Unctuous touch. Odor threshold 0.4 ppb.

공기와 물의 반응

Insoluble in water.

반응 프로필

Iodoform decomposes at high temperatures. Decomposes slowly in light at room temperature. Reacts violently with lithium. Is incompatible with mercuric oxide, calomel, silver nitrate, tannin, and balsam Peru. Is also incompatible with strong bases, strong oxidizing agents and magnesium. Vigorous reactions occur with acetone in the presence of solid potassium hydroxide or calcium hydroxide, hexamethylenetetramine at 352° F, mercury(I) fluoride and finely divided reduced silver.

위험도

Irritant. Decomposes violently at 400F (204C).

건강위험

Iodoform causes central nervous system depression and damage to the kidneys, liver, and heart.

화재위험

Literature sources indicate that Iodoform is nonflammable.

Carcinogenicity

Iodoform has been included in the NCI daily bioassay program. According to their summary: the high and low time-weighted average daily dosages of iodoform were, respectively, 142 and 71 mg/kg for male rats, 55 and 27 mg/kg for female rats, and 93 and 47 mg/kg for male and female mice. A significant positive association between dosage and mortality was observed in male rats but not in female rats or in mice of either sex. Adequate numbers of animals in all groups survived sufficiently long to be at risk from late-developing tumors. No statistical significance could be attributed to the incidences of any neoplasms in rats or mice of either sex when compared to their respective controls. Under the conditions of this bioassay, no convincing evidence was provided for the carcinogenicity of iodoform in Osborne–Mendel rats or B6C3F1 mice.

Purification Methods

Crystallise it from MeOH, EtOH or EtOH/EtOAc. It is steam volatile. It is a disinfectant. [Beilstein 1 IV 97.]
