It is also called Kipp's gas generator. It is a device invented by Petrus Jacobus Kipp (1808-1864), a Dutch chemist and physicochemical instrument maker, and is used to continuously generate gas by reacting a liquid reagent with a solid lump. It is suitable for obtaining small amounts of gas as needed in laboratories. As shown in , it is a glass apparatus consisting of a large funnel A and a narrowed container. Solid reagent is placed in the bulb B without dropping to the bottom C, and funnel A is attached. When liquid reagent is poured from A, it reaches B via C and the gas generating reaction begins. Tap D is opened to extract the required amount of gas. When D is closed, the pressure of the generated gas pushes down the liquid level, and the gas generating reaction stops. Tap E is the waste liquid outlet. It is used to generate hydrogen sulfide from iron sulfide and sulfuric acid, hydrogen from zinc and hydrochloric acid, carbon dioxide from marble and hydrochloric acid, and oxygen from manganese dioxide and hydrogen peroxide.[Iwamoto Shinbu] ©Shogakukan "> Kip's device (Diagram) Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
キップガス発生器ともよばれる。オランダの化学者・理化学器械製作者キップPetrus Jacobus Kipp(1808―1864)が発明した装置で、塊状の固体試薬に液体試薬を作用させて気体を連続的に発生させるのに用いる。実験室で、必要に応じて少量の気体を得るのに適している。 のように、大形の漏斗(ろうと)Aと、くびれのある容器からなるガラス器具で、球部Bに底部Cへ落とさないよう固体試薬を入れ、漏斗Aを装着する。Aから液体試薬を注ぐと、Cを経てBに達し、気体発生反応が始まる。コックDを開いて気体を必要量だけ取り出す。Dを閉めると、発生した気体の圧力によって液面が押し下げられ、気体発生反応がやむ。コックEは廃液排出口である。硫化鉄と硫酸による硫化水素、亜鉛と塩酸による水素、大理石と塩酸による二酸化炭素、二酸化マンガンと過酸化水素による酸素などの発生に利用される。[岩本振武] ©Shogakukan"> キップの装置〔図〕 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
