Butyl chloride is used as a solvent; as
a medicine to control worms, and to make other chemicals | [Fire Hazard]
Special Hazards of Combustion Products: May produce phosgene gas in fire | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this 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 medical
facility.
When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting.
Do not make an unconscious person vomit | [Shipping]
UN1127 Chlorobutanes require, Hazard Class: 3;
Labels: 3—Flammable liquid | [Incompatibilities]
Vapor may form explosive mixture with
air. May accumulate static electrical charges, and may
cause ignition of its vapors. Water contact slowly forms
hydrochloric acid. 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, alkaline earth, and alkali
metals; finely divided metal. Attacks metals in presence of
moisture. Attacks some plastics, rubber, or coatings | [Description]
Butyl chloride is a highly flammable, clear,colorless liquid. Molecular weight = 92.6 (n- and sec-isomers); Boiling point = 77℃; 69℃ (sec-isomer); Specificgravity (H2O:1) = 0.89; Freezing/Melting point =-123℃; Flash point = 9℃; - 10℃ (sec-isomer);Relative vapor density (air =1) = 3.2 (n- and sec-isomers);Vapor pressure = 81 mmHg at 20℃; Autoignitiontemperature = 240℃. Explosive limits: LEL = 1.8%;UEL = 10.1%. Insoluble in water. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 3, Reactivity 0; (sec-) Health 2, Flammability4, Reactivity 0. Practically insoluble in water;solubility = 0.7% at 12℃. | [Chemical Properties]
1-Chlorobutane is a highly flammable, clear, colorless liquid at standard temperature and pressure. The density is 0.886 g/cm3, which is lower than that of water. It does not react with water, is classified as highly flammable, but it is neither an oxidizer nor an explosive. However, vapors can form explosive mixtures with air. The substance self-ignites at 245℃. | [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. | [Uses]
1-Chlorobutane is used as an intermediate for the production of other chemicals in the chemical industry.
1-chlorobutane is a common extraction solvent in the forensic toxicology arena. A benefit of 1-chlorobutane is that it is less dense than water and therefore settles above the aqueous layer.
As butylating agent in organic synthesis, e.g., in the manufacture of butyl cellulose.
1-chlorobutane will be halogenated to produce dichlorobutane using sulfuryl chloride via a free-radical chain reaction mechanism.
| [Preparation]
1-Chlorobutane is obtained by esterification of n-butanol with hydrogen chloride or hydrochloric acid at 100℃ either without a catalyst or utilizing the accelerating effect of zinc chloride, tripentylamine hydrochloride, or phosphorus pentachloride. n-Butyl chloride is also obtained, along with 2-chlorobutane, by the chlorination of butane over aluminum oxide at 200℃. | [Synthesis Reference(s)]

Flammable | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Butyl chloride is incompatible with oxidizers (such as perchlorates, peroxides, permanganates, chlorates and nitrates).Store in tightly closed containers in a cool, well-ventilatedarea. Sources of ignition, such as smoking and open flames,are prohibited where Butyl chloride is handled, used, orstored. Metal containers involving the transfer of 5 gallonsor more of Butyl chloride should be grounded and bonded.Drums must be equipped with self-closing valves, pressurevacuum bungs, and flame arresters. Use only nonsparkingtools and equipment, especially when opening and closingcontainers of Butyl chloride. | [Purification Methods]
Shake it repeatedly with conc H2SO4 (until no further colour develops in the acid), then wash it with water, aqueous NaHCO3 or Na2CO3, and more water. Dry it with CaCl2, or MgSO4 (then with P2O5 if desired), decant and fractionally distil it. Alternatively, a stream of oxygen continuing ca three times as long as is necessary to obtain the first coloration of starch iodide paper by the exit gas. After washing with NaHCO3 solution to hydrolyse ozonides and to remove the resulting organic acid, the liquid is dried and distilled [Chien & Willard J Am Chem Soc 75 6160 1953].
