Title (EN) POWDERY COMPOSITION FOR HEXAVALENT CHROMIUM TREATMENT, TABLET, AND METHOD FOR PRODUCING LEATHER
(FR) COMPOSITION PULVÉRULENTE POUR TRAITEMENT DU CHROME HEXAVALENT, COMPRIMÉ, ET PROCÉDÉ DE PRODUCTION DE CUIR
(JA) 6価クロム処理用の粉末状組成物、錠剤および革の製造方法
Abstract:
(EN) A powdery composition for hexavalent chromium treatment includes a hexavalent-chromium-reducing compound component capable of reducing hexavalent chromium to trivalent chromium, and a component capable of trapping the moisture in air and capable of dissolving in water, the hexavalent-chromium-reducing compound component including an organic compound (A) that has a structure represented by chemical formula (1) having the property of acting on hexavalent chromium to reduce the same to trivalent chromium and also has a hydroxyphenyl group, and does not have an aldehyde group or a carboxyl group.
(FR) L'invention concerne une composition pulvérulente pour traitement du chrome hexavalent qui comprend un composant de composé réducteur de chrome hexavalent capable de réduire le chrome hexavalent en chrome trivalent, et un composant capable de piéger l'humidité dans l'air et capable de se dissoudre dans l'eau, le composant de composé réducteur de chrome hexavalent comprenant un composé organique (A) qui a une structure représentée par la formule chimique (1) ayant la propriété d'agir sur du chrome hexavalent pour réduire celui-ci en chrome trivalent, et a également un groupe hydroxyphényle, et ne possède pas de groupe aldéhyde ou de groupe carboxyle.
(JA) 6価クロム処理用の粉末状組成物は、6価クロムを3価クロムに還元し得る6価クロム還元化合物成分と、空気中の水分をトラップできるとともに、水に溶解できる成分とを含み、前記6価クロム還元化合物成分が、6価クロムと作用して3価に還元性を有する化学式(1)に示される構造およびヒドロキシフェニル基を有し、かつ、アルデヒド基およびカルボキシル基を有さない、有機化合物(A)を含む。
