用途
レシプロ式冷凍機用冷媒
化学的特性
Dichlorofluoromethane is a heavy, colorless
gas or liquid (below 9C) with a slight ethereal odor.
使用
Fire extinguishers; solvent; refrigerant.
一般的な説明
Dichloromonofluoromethane is a colorless, odorless gas. Dichloromonofluoromethane is shipped as a liquid under its own vapor pressure. Contact with the liquid may cause frostbite to unprotected skin. Dichloromonofluoromethane can asphyxiate by displacement of air. Exposure of the container to prolonged heat or fire may cause Dichloromonofluoromethane to rupture violently and rocket.
空気と水の反応
Slightly soluble in water.
反応プロフィール
Dichloromonofluoromethane is incompatible with the following: Chemically-active metals such as sodium, potassium, calcium, powdered aluminum, zinc & magnesium; acid; acid fumes .
健康ハザード
INHALATION: May cause giddiness, light-headedness, disorientation, nausea, vomiting, narcosis, cardiac dysrhythmias, hypotension, and death. SKIN: May cause frostbite or irritation. EYES: May cause irritation or cold injury.
火災危険
Special Hazards of Combustion Products: Toxic fumes of chlorine and fluorine may be produced in fire.
安全性プロファイル
Mildly toxic by
inhalation. Experimental reproductive
effects. When heated to decomposition it
emits very toxic fumes of Cl and F-.
職業ばく露
This material is used as a refrigerant
and a propellant gas.
環境運命予測
Chemical/Physical. The experimental hydrolysis half-life of dichlorofluoromethane in water at
25 °C and pH 7 is 234 yr (Jeffers and Wolfe, 1996).
輸送方法
UN1029 Dichlorofluoromethane or Refrigerant
gas R-21 Hazard Class: 2.2; Labels: 2.2-Nonflammable
compressed gas. 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.
不和合性
Reacts violently with chemically active
metals: sodium, potassium, calcium, powdered aluminum;
zinc, magnesium, alkali, alkaline earth. Reacts with acids or
acid fumes producing highly toxic chlorine and fluorine
fumes. Attacks some forms of plastics, rubber, and coatings.
廃棄物の処理
Return refillable compressed
gas cylinders to supplier. Incineration, preferably after mixing with another combustible fuel. Care must be exercised
to assure complete combustion to prevent the formation of
phosgene. An acid scrubber is necessary to remove the halo
acids produced. Because of recent discovery of potential
ozone decomposition in the stratosphere, this material
should be released to the atmosphere only as a last resort
