The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Only chloroform has significant applications of the haloforms. In the predominant application, chloroform is required for the production of tetrafluoroethylene (TFE), precursor to teflon . [ 1 ] Chloroform is fluorinated by reaction with hydrogen fluoride to produce chlorodifluoromethane (R-22).
Incapacitating agent is a chemical or biological agent which renders a person unable to harm themselves or others, regardless of consciousness. [1]Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios.
In addition, a variety of simple chlorinated hydrocarbons including dichloromethane, chloroform, and carbon tetrachloride have been isolated from marine algae. [7] A majority of the chloromethane in the environment is produced naturally by biological decomposition, forest fires, and volcanoes.
Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value.Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation.
‘I watched him put his chloroform on my hamster and kill him in front of me,’ Perry recalled ... Deadly Eaton and Palisades fires 100% contained after 24 days. Advertisement.
A diagram of a killing jar, with potassium cyanide at the bottom covered by plaster of Paris. The most common killing agents are ether, chloroform and ethyl acetate.Ethyl acetate has many advantages and is very widely used.
