MSDS Information

• 2-Bromoethylamine hydrobromide

2-ブロモエチルアミン臭化水素酸塩 化学特性,用途語,生産方法

• 外観

  白色～わずかにうすい褐色, 結晶～粉末又は塊

• 溶解性

  水に溶けやすく、エタノール及びアセトンに溶けにくい。

• 化学的特性

  slight yellow to white crystalline powder. Soluble in water and methanol, insoluble in ether. Hygroscopic and moisture sensitive. Incompatible with strong oxidizing agents.

• 使用

  2-Bromoethylamine hydrobromide is used to construct C2-symmetric imidazolidinylidene ligands with a dioxolane backbone. It acts as a building block which is used for proteomics research. It is also used as organic and pharmaceutical intermediates for the preparation of first-aid medicines.

• 主な応用

  2-Bromoethylamine hydrobromide (BEA-HBr) can be used as a reactant in the preparation of:
  Amino-functionalized ionic liquid, 1-aminoethyl-3-methylimidazolium hexafluorophosphate ([2-aemim][PF6]). [2-aemim][PF6] is employed as a catalyst in the synthesis of 4H-pyrans derivatives by treating with aromatic aldehydes, malononitrile, ethyl acetoacetate via Knoevenagel condensation reaction.
  2-(N-aryl-N-aroyl)amino-4,5-dihydrothiazole derivatives via cyclocondensation reaction.
  It can be also employed as an alkylating agent for the surface modification of nylon to obtain primary/secondary/tertiary amine groups.

• 製造方法

  2-Bromoethylamine hydrobromide was synthesized by bromination of ethanolamine. Drop into hydrobromic acid in the reaction pot, cool, add ethanolamine dropwise under stirring, and finish adding dropwise within half an hour, then steam the hydrobromic acid of 85% of the input quantity (the feed quantity of hydrobromic acid is 8.89 times the weight of ethanolamine) , about 20h steamed. After the concentrated solution is cooled to 70-80°C, it is put into pre-chilled acetone, cooled to below 5°C, and the crystallized 2-bromoethylamine hydrobromide is filtered out. Yield 70%.

• 一般的な説明

  Crystals.

• 空気と水の反応

  Water soluble.

• 反応プロフィール

  The acidic organic salt (HBr) of the amine. Acidic salts are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

• 健康ハザード

  ACUTE/CHRONIC HAZARDS: When heated to decomposition 2-Bromoethylamine hydrobromide emits very toxic fumes of bromide ion, NOx and hydrogen bromide.

• 火災危険

  Flash point data for 2-Bromoethylamine hydrobromide are not available; however, 2-Bromoethylamine hydrobromide is probably combustible.
