• 化学的特性

  1,2-Butylene oxide is a colorless mobile liquid with an unpleasant smell. This low boiling liquid has but limited water solubility, yet is miscible with most common organic solvents. It undergoes the usual reactions of epoxides with compounds having labile hydrogen atoms. Some of these are acids, amines, ammonia, alcohols, phenols, polyols, thiols, etc. Butylene oxide can be polymerized or copolymerized with other alkylene oxides to yield polyethers. The resulting polymers are less water soluble than the polymers made from ethylene and propylene oxide, of equivalent chain length.

• 使用

  Intermediate for various polymers, stabilizer for chlorinated solvents.

• 一般的な説明

  A clear colorless volatile liquid with an ethereal odor. Flash point near 0°F. Density about 6.9 lb / gal. Soluble in water. Boiling point near 140°F. Flammable over a wide range of vapor-air concentrations. May polymerize with the evolution of heat and possible rupture of container if contaminated. Vapors irritate eyes, skin and respiratory system. Prolonged contact with skin may cause in delayed burns. Vapors are heavier than air. Used as an intermediate to make various polymers. Chemicals that polymerize are often stabilized by refrigeration.

• 空気と水の反応

  Highly flammable. Soluble in water and may decompose upon contact with water.

• 反応プロフィール

  Epoxides, such as 1,2-EPOXYBUTANE, are highly reactive. They polymerize in the presence of catalysts or when heated. Contact with anhydrous metal halides; amino, hydroxyl and carboxyl functions; inorganic acids and charcoal may cause polymerization. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.

• 危険性

  Toxic concentration of vapors occurs at room temperature. Highly flammable, dangerous fire risk. Possible carcinogen.

• 健康ハザード

  Inhalation: intolerable odor and irritation; respiratory injury may occur at higher levels. Ingestion causes irritation of mouth and stomach. Contact with either liquid or vapor may cause burns of eyes. Liquid produces frostbite-type of skin burn if free to evaporate; if confined to skin, burn may cause skin sensitization; not readily absorbed in toxic amounts.

• 火災危険

  Behavior in Fire: Containers may explode in fire. Use water to cool container from safe distance.

• 安全性プロファイル

  Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by ingestion and skin contact. Mtldly toxic by inhalation. Experimental reproductive effects. Mutation data reported. Dangerous fire hazard when exposed to heat, flame, or powerful oxidizers. To fight fire, use dry chemical, water spray, mist or fog, alcohol foam. When heated to decomposition it emits acrid smoke and fumes.

• 職業ばく露

  It is used as a stabilizer in chlorinated solvents, and to make other chemicals, such as gasoline additives.

• 発がん性

  Exposure to 1000 ppm before and during gestation did not cause any teratogenic effects in rats; fetal growth and viability were not affected despite depressed maternal body weight gain.6 Rabbits exposed at 250 or 1000ppm 7 hours/day during gestational days 0 to 24 had maternal deaths at both exposure concentrations. No teratogenic effects were observed, although the pregnancy rate was reduced in the high-dose group. 1,2-Epoxybutane is a direct-acting alkylating agent, and it is genotoxic in a wide range of assays.
  Instilled in the eyes of rabbits, 1,2- epoxybutane caused corneal injury.
  A threshold limit value (TLV) has not been established for 1,2-epoxybutane, although US manufacturers have recommended a voluntary time-weighted average-threshold limit value of 40ppm.

• 輸送方法

  UN3022 1,2-Butylene oxide, stabilized, Hazard Class: 3; Labels: 3—Flammable liquid

• 純化方法

  Dry it with CaSO4, and fractionally distil it through a long (126cm) glass helices-packed column. The first fraction contains a water azeotrope. [Beilstein 17 II 17.]

• 不和合性

  May form explosive mixture with air. Unless inhibited, can form unstable and explosive peroxides. Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Polymerization will occur in the presence of acids, strong bases and chlorides of tin, iron and aluminum. Storage tanks and other equipment should be absolutely dry and free from air, ammonia, acetylene, hydrogen sulfide, rust and other contaminants. 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. Attacks some plastics. May accumulate static electric charges that can result in ignition of its vapors. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045.
