액화석유가스 C화학적 특성, 용도, 생산
화학적 성질
LPG is a colorless, noncorrosive, odorless
mixture of gases when pure. A foul-smelling odorant is
usually added. Shipped as a liquefied compressed gas (a
mixture of propane, butanes, propylene, and butylenes)
용도
As fuel; in production of chemicals
일반 설명
A mixture of butane, isobutane, propane, propylene, butylenes and other hydrocarbons of low molecular weight that is refined from petroleum. Maintained as a liquid under pressure. Leaking vessels can release either the liquid, which quickly vaporizes, or the gaseous mixture. The gas is heavier than air-- a flame can flash back to the source of the leak very easily. Under prolonged exposure to heat the containers may rupture violently and rocket. Used as a fuel, an aerosol propellant, in cigarette lighters, and to make other chemicals.
공기와 물의 반응
Highly flammable. No reaction with water.
반응 프로필
Saturated aliphatic hydrocarbons, contained in LPG, may be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
건강위험
Concentrations in air greater than 10%; cause dizziness in a few minutes, 1% concentrations give the same symptom in 10 min. High concentrations cause asphyxiation.
화재위험
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) 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.
잠재적 노출
LPG is used as a fuel propellant; in
metal cutting; and in the production of petrochemicals.
Incompatibilities: 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 awayfrom alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Contact with chlorine dioxide may
cause fire and explosions. Attacks some plastics, rubber
and coatings
운송 방법
UN1075 Petroleum gases, liquefied or Liquefied
petroleum gas; 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
