翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrogen odorant ： ウィキペディア英語版 Hydrogen odorant A hydrogen odorant in any form, is a minute amount of odorant such as ethyl isobutyrate, with a rotting-cabbage-like smell, that is added to the otherwise colorless and almost odorless hydrogen gas, so that leaks can be detected before a fire or explosion occurs. Odorants are considered non-toxic in the extremely low concentrations occurring in hydrogen gas delivered to the end user. The approach is not new, for the same safety reasons the odorant ''tert''-butyl mercaptan is used in natural gas. ==See also== *Odor detection threshold 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrogen odorant」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
