Chloroform?

Question

I am doing a chemistry project on chloroform and my questions are: what is the First Aid information if ingested? And what are the uses of this chemical? Also, anyone have any pictures of it?

Answer 1

Chloroform is a halogenoalkane (When CH4 (methane) is mixed with Cl2 and UV light). When this happens, hydrogen atoms are broken off CH4 and a number of chlorine atoms are bonded. In this process, CH3Cl, CH2Cl2, CHCl3, and CCl4 are formed in different random quantities. These are later distilled and you can get pure chloroform (CHCl3). Impress your teacher.

The First Aid information of using chloroform is that it can make you nauseous and can have other serious problems with your lungs. This chemical is used to make people fall asleep (as far as I know). It might also be a good solvent...don't trust this. I don't have pics. Sorry.

Answer 2

Chloroform is a liquid that evaporates quickly. The chemical formula of chloroform is CH(Cl)3. The gas used to be used as an anesthetic in the 1800s, but is no longer used in medicine. If ingested induce vomiting and seek medical treatment immediately. Today the chemical is primarily used as a solvent in organic chemistry reactions. You would be hard pressed to find pictures of chloroform. But you could find a picture of its chemical structure on any chemical distribution website such as Sigma-Aldrich. The molecule is centered on the carbon atom with a hydrogen and three chlorines attached to the central carbon.

Answer 3

Chloroform, a relitively simple hydrocarbon, is composed of three chlorines, a carbon and a hydrogen atom. Because chlorine is hazardous chloroform can act as a pesticide. However chloroform as an anesthetic is no longer used because it can cause cancer, cardiac problems and even miscarriage. The most important first aid i can recomend is calling an ambulance however if is accidentally inhaled from freon leaks, water chlorination, cleaning product byproduct etc.. perhapes medical persons should be consulted even if there are no imediate effects. As to your last question, chloroform is colorless as a liquid and a gas so it maybe difficult to find images of it.

Answer 4

I don't know if you could knock out Kong like they did in the movie, but Chloroform will definitely make people unconcious. For decades, it was the anesthetic of choice for surgery.

Answer 5

Ingestion:
Aspiration hazard. May cause central nervous system depression, kidney damage, and liver damage. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause cardiac disturbances. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal.

Uses -
In the late 19th and early 20th centuries, chloroform was used as an inhaled anesthetic during surgery. However, safer, more flexible drugs have entirely replaced it in this role. The major use of chloroform today is in the production of the freon refrigerant R-22. However, as the Montreal Protocol takes effect, this use can be expected to decline as R-22 is replaced by refrigerants that are less liable to result in ozone depletion.

Smaller amounts of chloroform are used as a solvent in the pharmaceutical industry and for producing dyes and pesticides. It is used as a solvent for research in academic chemistry laboratories, also. As a solvent it can be used to bond pieces of acrylic glass (which is also known under the trade name 'Perspex'). Chloroform is one of the most effective known solvents for alkaloids in base form, and may be used to extract nitrogenous chemicals from plant material for pharmaceutical processing. It is commercially used to extract morphine from poppies, scopolamine from Datura plants, and so on.

Chloroform reacts with aqueous sodium hydroxide (preferably in the presence of a phase transfer catalyst) to produce dichlorocarbene. This is used to effect ortho-formylation of activated aromatic rings such as phenols, producing aryl aldehydes in a reaction known as the Reimer-Tiemann reaction. Alternatively the carbene may be trapped by an alkene to form a cyclopropane derivative.

Chloroform containing deuterium (heavy hydrogen), CDCl3, is the most common solvent used in NMR spectroscopy.

Safety -
As might be expected from its use as an anesthetic, inhaling chloroform vapors depresses the central nervous system.

Breathing about 900 parts of chloroform per million parts air (900 parts per million) for a short time can cause dizziness, fatigue, and headache.

Chronic chloroform exposure may cause damage to the liver (where chloroform is metabolized to phosgene) and to the kidneys, and some people develop sores when the skin is immersed in chloroform. Approximately 10% of the population has an allergic reaction to chloroform that produces a fever of around 40°C (104°F) upon exposure.

Animal studies have shown that miscarriages occur in rats and mice that have breathed air containing 30 to 300 ppm chloroform during pregnancy and also in rats that have ingested chloroform during pregnancy. Offspring of rats and mice that breathed chloroform during pregnancy have a higher incidence of birth defects, and abnormal sperm have been found in male mice that have breathed air containing 400 ppm chloroform for a few days. The effect of chloroform on reproduction in humans is unknown.

Chloroform once appeared in toothpastes, cough syrups, ointments, and other pharmaceuticals, but it has been banned in consumer products in the United States since 1976.

The NTP's eleventh report on carcinogens implicates it as reasonably anticipated to be a human carcinogen, a designation equivalent to IARC class 2A. It has been most readily associated with hepatocellular carcinoma.

Caution is mandated during its handling in order to minimize unnecessary exposure; safer alternatives, such as dichloromethane, have resulted in a substantial reduction of its use as a solvent.

During prolonged storage hazardous amounts of phosgene can accumulate in the presence of oxygen and ultraviolet light. To prevent accidents commercial material is stabilized with ethanol or amylene, but samples that have been recovered or dried no longer contain any stabilizer and caution must be taken with those. Suspicious bottles should be tested for phosgene. Filter paper strips, wetted with 5% diphenylamine, 5% dimethylaminobenzaldehyde, and then dried, turn yellow in phosgene vapor.

Due to its volatile nature, laboratory work with chloroform should be performed under a fume hood to avoid inhaling its fumes. Another problem with its volatility is that it can be difficult to pipette.

Was that was the RAGGED allusion of that "jack flack" film, that all the kids liked... or was that ETHER? What does the CHLORO FORM? ~ lies or real info? what is the ACID TEST? ALTERNATE PATH LESSONS
