Title (EN) ODORANT ADSORBENT
(FR) ADSORBANT DE SUBSTANCES ODORANTES
(JA) 臭気物質の吸着剤
Abstract: front page image
(EN)An odorant adsorbent which comprises an acid hydrazide compound and silica, wherein the silica has a surface silanol group density of 5.0/nm2 or less. This odorant adsorbent can improve storage stability even in the case where a hydrazine compound is mixed with silica.
(FR)L’adsorbant de substances odorantes de l’invention comprend un composé hydrazide acide et une silice. Ladite silice présente une densité de groupe silanol en surface inférieure ou égale à 5.0/nm2. Cet adsorbant de substances peut présenter une amélioration de stabilité de conservation, y compris dans le cas où un composé hydrazine et la silice sont mélangés.
(JA)酸ヒドラジド化合物及びシリカを含有し、且つ、前記シリカは、表面のシラノール基密度が5.0個/nm2以下である、臭気物質の吸着剤は、ヒドラジン化合物とシリカとを混合した場合にも、貯蔵安定性を向上することができる。
