1-Bromobutane Chemical Properties,Usage,Production

Description

Butyl bromide is a highly flammable, colorlessliquid with a pleasant odor. Molecular weight = 137.04.Boiling point =101.6℃; Specific gravity (H2O:1) = 1.276at 20℃; Freezing/Melting point = 2112.4; Vapor density(air 5 1) = 4.68; Flash point =18℃ (21℃ for sec-isomer).Autoigniton temperature = 265℃. Explosive limits:LEL =2.6% at 100℃; UEL =6.6% at 100℃. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 3, Reactivity 0. Insoluble in water.

Chemical Properties

1-bromobutane appears as a clear colorless to slightly yellow liquid with aroma. Flash point 65°F. Denser than water and insoluble in water, soluble in organic solvents such as alcohol, ether and chloroform.Vapors heavier than air.

Uses

1-Bromobutane is used as an intermediate in organic synthesis and as a solvent for cleaning and degreasing. It acts as an alkylating agent as well as to prepare organometallic compounds such as n-butyllithium. It is also involved in the synthesis of procaine and tetracaine. It reacts with magnesium metal to prepare the Grignard reagent, which is used to form carbon-carbon bonds.

Application

1-Bromobutane may be used as a derivatization reagent for multiple functional groups (amino, carboxyl, and phenolic hydroxyl groups) of amino acids to improve hydrophobicities and basicities of the amino acids. It may also be used as an internal standard for the quantification of 1- and 2-bromopropane in human urine by headspace gas chromatography.

General Description

1-Bromobutane, an alkyl halide, is an alkylating agent. Its rotational constants, nuclear quadrupole constants and centrifugal distortion constants have been stated based on microwave spectral data. The rate coefficient for the reaction of 1-bromobutane with hydrogen atoms has been reported to be 2.4±1.2x1010cm3mol-1s-1.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

1-Bromobutane is incompatible with strong bases and oxidizers [USCG, 1999].

Hazard

Flammable, dangerous fire risk.

Health Hazard

Irritating to the eyes, nose, throat, and upper respiratory tract. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Irritating to the skin.

Safety Profile

Moderately toxic by intraperitoneal route. Mddly toxic by inhalation. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Violent reaction with bromobenzene + sodium above 30℃. Can react with oxidizing materials. To fight fire, use CO2, dry chemical, mist or spray. See also BROMIDES.

Synthesis

1-bromobutane is a primary alkyl halide (primary alkyl) and therefore it is produced from bimolecular nucleophilic substitution reactions (Sn2).
The preparation method of 1-bromobutane is as follows: stirring n-butanol, sodium bromide, water and sulfuric acid evenly, heating under reflux for 3 hours, steaming out the crude bromobutane, washing with water, treating with cold concentrated sulfuric acid, and distilling to obtain the finished product.
Reaction equation: CH3CH2CH2CH2OH+NaBr+H2SO4→CH3CH2CH2CH2Br+Na2SO4+H2O
This halide is easily prepared by reacting butan-1-ol (primary alcohol) with sodium bromide solution and excess of concentrated sulfuric acid. The reaction between sodium bromide and sulphuric acid origins hydrobromic acid.

Potential Exposure

Butyl bromide is used to make otherchemicals and in making pharmaceuticals.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

storage

Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with Butyl bromide you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area. Sources of ignition, such as smoking and open flames, are prohibitedwhere Butyl bromide is handled, used, or stored. Metal containers involving the transfer of 5 gallons or more of Butylbromide should be grounded and bonded. Drums must beequipped with self-closing valves, pressure vacuum bungs,and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers ofButyl bromide.

Shipping

UN1126 & UN23391- & 2-Bromobutane, Hazard Class: 3; Labels: 3—Flammable liquid.

Purification Methods

Wash the bromide with conc H2SO4, water, 10% Na2CO3 and again with H2O. Dry it over CaCl2, CaSO4 or K2CO3, and distil it. Redistil it after drying with P2O5, or pass it through two columns containing 5:1 silica gel/Celite mixture and store it with freshly activated alumina. [Beilstein 1 IV 258.]

Incompatibilities

Vapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May accumulate static electrical charges and cause ignition of its vapors.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed
