Carbon Tetrabromide Preparation

This compound can be prepared by the bromination that methane (CH4). The reaction also uses hydrogen bromide (HBr) or bromine (Br2). The reaction in between methane and bromine wake up in the complying with way:


*
snapshot 1 – Carbon Tetrabromide

CH4 + 2Br2 = CBr4 (Carbon Tetrabromide) + 2H2

It can additionally be prepared in a more economic means using tetrachloromethane v aluminum bromide. This reaction takes ar in 100 °C temperature.

Carbon Tetrabromide Formula

The molecule formula because that Carbon Tetrabromide is CBr4.

Carbon Tetrabromide physical and Chemical Properties

Appearance: This compound has actually a colorless crystalline appearance.

Odor: It has a slim distinctive odor.

Density: It has actually a thickness of 3.42 g /cm3 in its solid state. Liquid Carbon Tetrabromide has a density of 2.961 g/cm3 in ~ 100 °C temperature.

Solubility: it is insoluble in water.

Melting Point: The melting point of this product is 91.0 °C.

Boiling Point: Its boiling point is 189.5 °C.

Vapor Pressure: It has actually a vapor push of 5.33 kPa at 96.3 °C temperature.

Carbon Tetrabromide Structure

This crystalline compound has a monoclinic decision structure. The molecules of Carbon Tetrabromide are tetrahedral. It method the atoms room arranged in a tetrahedral manner within each molecule that this compound.

Carbon Tetrabromide Plastic Crystallinity

The high temperature alpha (α) step of the Carbon Tetrabromide molecules is called a plastic crystal phase. This molecules space positioned top top the corners and the facility of the encounters of the cubic unit cell in one fcc arrangement. Earlier it was believed that the molecule of this link were able to rotate virtually freely (a ‘rotor phase’), which might make them look choose spheres after an median time. However, resent studies present them come be minimal to 6 possible orientations (Frankel disorder). In addition, this molecular orientations do not occur totally independently. Sometimes the bromine atom of various neighboring molecule come very close come each various other leaving tiny space for independent orientation. This prevents certain orientational combinations in between two surrounding molecules. These difficulties cause significant amounts the disorder within the crystals of this carbon bromide compound resulting in high-structured sheets of diffusive intensity in X ray diffraction. The defense intensity framework provides in-depth information about this structure.

Carbon Tetrabromide Reactions

This crystalline link is used in the Appel reaction in addition to triphenylphosphine. Appel reaction is an essential reaction in i beg your pardon alcohols are converted to alkyl bromides. Carbon Tetrabromide is provided for this purpose as it reflects much much less stability 보다 lighter tetrahalomethanes.

Carbon Tetrabromide Uses

There are countless industrial applications that this carbon bromide such as:

It is frequently used together a solvent because that waxes, greases and also oils.Carbon Tetrabromide is used for the purpose of blowing and vulcanization in rubber and also plastic industries.This link is supplied as a polymerizing agent.It additionally has intermediate applications in agrochemical manufacturing.It is offered as sedative.This non-flammable product is often used for producing fire resistant chemicals and various photochemical compounds.Due to its high density, it is offered for separating various minerals.

Carbon Tetrabromide MSDS

This crystalline link can reason serious health and wellness hazards in situation of end exposure. It is vital to take appropriate precautions while dealing with this material.

Toxicology

This substance have the right to have hazardous health impacts in situation of eye contact, inhalation and also ingestion. It can also cause skin irritation if involves direct contact. This material deserve to be toxic to different human guts such as lungs, kidney, liver and upper respiratory tract.

First help Measures

Eye Contact: In situation of direct eye contact, one should immediately remove any type of contact lenses. The is essential to do the washing up the eyes through plenty of lukewarm water at the very least for 15 minutes. Immediate medical help is required.

Skin Contact: The victim have to wash the influenced skin area v a disinfectant soap and plenty the water. Applying an Emollient can aid in reduce the irritation. One should get medical help if the wake up persists.

Inhalation: The victim must be eliminated to fresh air. One must loosen any kind of tight clothes such as collar, belt and tie. Oxygen or synthetic respiration must be provided if the victim is enduring breathing difficulty. Performing mouth-to-mouth resuscitation deserve to be hazardous because that the person giving the aid. Prompt medical fist is required.

Ingestion: It is not advisable come induce vomiting in situation of inadvertently ingestion of this material. Tight clothes should be removed. One should never provide anything through mouth if the victim is unconscious. The is essential to achieve medical help as quickly as feasible in case large amounts of this material have been ingested.

Personal safety Measures

NIOSH approved dust respirator, rap coats, security goggles and also protective gloves must be provided for proper personal protection.

Fire Fighting Measures

Carbon Tetrabromide is a non-flammable substance. However, the containers save on computer this substance might explode when concerns contact v heat. Because of this reason, fire fighters need to use proper fire fighting gear and also protective clothes when extinguishing a fire around it.

Accidental relax Measure

One can use a shovel to clean this product in situation of huge spillage. Proper waste disposal containers need to be supplied for getting rid of of the spilled material.

Storage Instruction

It should be save in strict sealed containers in a cool and also well ventilated area.

Carbon Tetrabromide Price and also Availability

This colorless crystalline compound is obtainable in miscellaneous purity grades. Countless companies roughly the people supply this material. The price for 100 gm that this material ranges in between $130 and $ 160 depending upon the top quality of the product.
