Ether is flammable physical or chemical
By the time the American Civil War broke out inboth ether and chloroform had been in use for several years as methods of surgical anesthesia. Though both anesthetic agents were developed around the same time the schloroform soon emerged as the more widely used, as it took action faster and was non-flammable. During the Civil War, ether and particularly chloroform became indispensable tools for military doctors, who performed tens of thousands of amputations and other types of procedures for wounded Union and Confederate soldiers.
Before its development as a surgical anesthetic, ether was used throughout the history of medicine, including as a treatment for ailments such as scurvy or pulmonary inflammation.
A pleasant-smelling, colorless and highly flammable liquid, ether can be vaporized into a gas that numbs pain but leaves patients conscious.
InGeorgia physician Crawford Williamson Long became the first doctor to use ether as a general anesthetic during surgery, when he used it to remove a tumor from the neck of his patient James M. Long did not publish the results of his experiments untiland by that time Boston dentist William T.
Morton had already gained fame with the first publicly demonstrated use of ether as an effective surgical anesthetic. After watching his colleague Horace Wells unsuccessfully promote nitrous oxide as an anesthetic, Morton concentrated on the possibility of ether. Also called trichloromethane, chloroform is prepared through the chlorination of methane gas. It was first prepared in by the American chemist Dr. Samuel Guthrie, who combined whiskey with chlorinated lime in an attempt to produce a cheap pesticide.
Inthe Scottish physician Sir James Young Simpson first used the sweet-smelling, colorless, non-flammable liquid as an anesthetic. When administered by dripping the liquid onto a sponge or cloth held so that the patient inhaled the vapors, chloroform was seen to have narcotic effects on the central nervous system, and produced these effects relatively quickly.
On the other hand, there were higher risks associated with chloroform than with ether, and its administration required greater physician skill. There were early reports of fatalities due to chloroform, beginning with a year-old girl in Skill and care were required to differentiate between an effective dose enough to make patient insensible during surgery and one that paralyzed the lungs, causing death. Fatalities were widely publicized, and the risks involved led some patients facing surgery to decline anesthesia and brave the pain.
American military doctors began using ether as an anesthetic on the battlefield during the Mexican-American Warand by it was officially issued by the U. Though many army doctors and nurses had experience with using ether by the time of the Civil Warchloroform became more popular during that conflict, due to its faster-acting nature and a large number of positive reports of its usage during the Crimean War in the s.What is this information?

Instability 2 Readily undergoes violent chemical changes at elevated temperatures and pressures. A clear colorless liquid. May polymerize if contaminated or subjected to heat.
If polymerization take place inside a container, the container may violently rupture. Vapors are heavier than air. The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. Highly Flammable Polymerizable Peroxidizable Compound.

When ethers containing peroxides are heated distilled they can detonate [Lewis, 3rd ed. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back.
Most vapors are heavier than air. They will spread along ground and collect in low or confined areas sewers, basements, tanks. Vapor explosion hazard indoors, outdoors or in sewers.
Those substances designated with a P may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. ERG, Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution. A very dangerous fire hazard when exposed to heat, flame or strong oxidizing agents. Highly explosive in the form of vapor when exposed to open flame or sparks.Use caution: Liquids with this reactive group classification have been known to react with the absorbent listed below.

What is this information? Department of Transportation hazard labels, and a general description of the chemical. A colorless gas. Heavier than air. Easily liquefied. Contact with the unconfined liquid may cause frost bite by evaporative cooling. May asphyxiate by displacing air. A flame may flash back from a point of ignition to source of a leak.
Under prolonged exposure to fire or heat containers may rupture violently and rocket. The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents.
Highly Flammable Peroxidizable Compound. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame.
Use an alternate method of detection thermal camera, broom handle, etc. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. ERG, Some may be irritating if inhaled at high concentrations.
Response Recommendations. The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid.

Excerpt from ERG Guide [Gases - Flammable Including Refrigerated Liquids ]: As an immediate precautionary measure, isolate spill or leak area for at least meters feet in all directions. Hydrogen and Methane mixture, compressed UN may burn with an invisible flame. Move containers from fire area if you can do it without risk. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur.Don't have a profile?Cukur season 1 full cast

Combustion is a chemical process.
Flammability is a property, not a change. But it is a chemical property. No it is a chemical property, because burning is a chemical reaction.
Evaporation of ether or any other substance is a physical change as the identity of the substance remains the same. It is not a change of any sort. It is a physical property. Petroleum ether or pet ether as it's commonly called does not have any particular chemical formula. All you can be relatively sure of is that there are ethers in it. There could be diethyl ether, butylpropyl ether, dipentyl ether Pet ether is a solvent, and as such it's not necessary to know its chemical formula.
It's simply a medium, not a reactant. Chemically, butyl ether is an ether. It may also be called a butoxy compound. Ether is the common name for the compound, diethyl ether.

There is little doubt, however, that it was William Thomas Green Morton who, on October 16,at Massachusetts General Hospital in Boston, first demonstrated before a gathering of physicians the use of ether as a general anesthetic.
The news…. Diethyl ether, for example, is a by-product of the large-scale synthesis of ethanol ethyl alcohol from ethylene. Both the alcohol and ether are valuable and can be separated easily. Codeine, a potent pain-relieving drug, is the methyl ether of morphine. Because ether is highly flammable, it has largely been replaced by less-flammable anesthetics, including nitrous oxide N 2 ….
