| Hazard Information | Back Directory | [Chemical Properties]
1-Butyne is a clear, colorless gas with a characteristic acetylenic odor. It is an extremely
flammable and reactive alkyune and may cause frostbite. It is insoluble in water. It is a
specialty gas mixture used in organic synthesis of compounds and instrument calibration;
it has no specifi c or signifi cant industrial application. On combustion, 1-butyne releases
carbon monoxide. | [General Description]
A colorless gas. Denser than air. Prolonged exposure to intense heat may cause the containers to rupture violently and rocket. | [Reactivity Profile]
ETHYL ACETYLENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic polymerization. | [Air & Water Reactions]
Highly flammable. | [Hazard]
Flammable, dangerous fire risk. | [Health Hazard]
1-Butyne probably has some anesthetic activity and can act as a simple asphyxiant. The
symptoms of poisoning include rapid respiration, muscular incoordination, fatigue, dizzi ness, nausea, vomiting, unconsciousness, and death. The toxicity of 1-butyne has not been
thoroughly investigated and the published information is very scanty | [Health Hazard]
Vapors may cause dizziness or asphyxiation without warning. Some may be toxic if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. | [Potential Exposure]
A simple asphyxiant. Ethyl acetylene
is used as a fuel and as a chemical intermediate. | [Fire Hazard]
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Silane will ignite spontaneously in air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. 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. | [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 if
heart 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. If
frostbite has occurred, seek medical attention immediately;
do NOT rub the affected areas or flush them with water. In
order to prevent further tissue damage, do NOT attempt to
remove frozen clothing from frostbitten areas. If frostbite
has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water. | [Shipping]
UN2452 Ethylacetylene, stabilized, Hazard
Class: 2.1; Labels: 2.1-Flammable gas. Cylinders must be
transported in a secure upright position, in a well-ventilated
truck. Protect cylinder and labels from physical damage.
The owner of the compressed gas cylinder is the only entity
allowed by federal law (49CFR) to transport and refill
them. It is a violation of transportation regulations to refill
compressed gas cylinders without the express written
permission of the owner | [Incompatibilities]
Extremely flammable; forms 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, copper and its alloys, and
various plastics including Teflon. May undergo violent
polymerization when subjected to heat, direct sunlight, or
contamination | [Description]
Ethyl acetylene is a colorless, compressed gasor liquid. Molecular weight = 54.0; Boiling point = 8.1℃;Freezing/Melting point = -130℃; Flash point = -7℃.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 4, Reactivity 2. Insolublein water. | [Waste Disposal]

2901230000 | [storage]
Cylinders of 1-butyne should be stored in well-ventilated areas, away from heat, flame,
and sparks and with proper valve protection caps on the cylinders when not in use.
Non-refi llable cylinders must be disposed of in accordance with federal, state, and local
regulations. | [Precautions]
Occupational workers should be very careful during handling/using 1-butyne cylinders,
which may rupture under fi re conditions, thereby forming an explosive mixture in air.
Also, the vapors of 1-butyne may travel a considerable distance to the source of ignition
and fl ash back. Workers should secure the cylinder when using to protect them from fall ing and a suitable hand truck should be used to move the cylinders. The workplace should
have adequate general and local exhaust ventilation to maintain concentrations below
flammable limits and to avoid asphyxiation. Workers should have proper protective gloves
and safety shoes to prevent contact with cold equipment. Workers should be cautious to
protect 1-butyne containers from physical damage, avoid defacing the cylinders or labels,
and the cylinders should be refi lled by qualifi ed producers of compressed gas. | [Safety Profile]
Probably an asphpant.
A very dangerous fire hazard when exposed
to heat, open flame, or powerful oxidzers.
A dangerous explosion hazard. To fight fire,
stop flow of gas. See also ACETYLENE
and ACETYLENE COMPOUNDS. |
