텔루르 헥사플루오르화물 화학적 특성, 용도, 생산

화학적 성질
Tellurium hexafluoride is a colorless gas with a repulsive odor.
생산 방법
Tellurium hexafluoride (TeF6) is prepared by the direct fluorination of tellurium metal. It is a by-product of ore refining.
일반 설명
TELLURIUM HEXAFLUORIDE is a colorless gas with a repulsive odor. TELLURIUM HEXAFLUORIDE is very toxic by inhalation and skin absorption. When heated to high temperatures, TELLURIUM HEXAFLUORIDE may emit toxic fluoride and tellurium fumes. TELLURIUM HEXAFLUORIDE is heavier than air. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket. TELLURIUM HEXAFLUORIDE reacts with water to yield toxic vapors.
공기와 물의 반응
TELLURIUM HEXAFLUORIDE reacts with water to yield toxic hydrogen fluoride vapors. TELLURIUM HEXAFLUORIDE emits very toxic fumes of fluoride and tellurium. Decomposes in water, acid, and alkali. [EPA, 1998].
반응 프로필
TELLURIUM HEXAFLUORIDE is a colorless, toxic gas, when heated to decomposition TELLURIUM HEXAFLUORIDE emits very toxic fumes containing metallic tellurium and tellurium fluorides [Lewis, 3rd ed., 1993, p. 1207].
건강위험
Capable of causing death or permanent injury. Acute -- the material is highly toxic by inhalation exposure and a strong irritant to skin, eyes, the lungs, the throat, and stomach. Death can occur from filling of the lungs with fluid (pulmonary edema) or from asphyxiation due to spasm of the throat (larynx) or bronchi. Those with impaired pulmonary function, especially obstructive airway diseases are at a greater risk.
화재위험
Container may explode in heat of fire. When heated to decomposition, TELLURIUM HEXAFLUORIDE emits very toxic fumes of fluoride and tellurium. Decomposes in water, acid, and alkali.
잠재적 노출
Tellurium hexafluoride is stated to be a by-product of ore refining.
운송 방법
UN2195 Tellurium hexafluoride, Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 8-Corrosive material, inhalation hazard zone A. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
비 호환성
Hydrolyzes slowly in water forming telluric acid. Emits highly toxic fumes when heated or on contact with acid or acid fumes.
폐기물 처리
Return refillable compressed gas cylinders to supplier. Nonrefillable cylinders should be disposed of in accordance with local, state and federal regulations. Allow remaining gas to vent slowly into atmosphere in an unconfined area or exhaust hood. Refillabletype cylinders should be returned to original supplier with any valve caps and outlet plugs secured and valve protection caps in place.
