Title
(EN) POROUS CELLULOSE BEADS AND METHOD FOR PRODUCING ADSORBENT
(FR) PERLES POREUSES DE CELLULOSE ET PROCÉDÉ DE PRODUCTION D'ADSORBANT
(JA) 多孔質セルロースビーズおよび吸着体の製造方法
Abstract
(EN) The present invention relates to a method for producing porous cellulose beads which comprises dispersing a phase, which is to be a dispersed phase and comprises either cellulose or a cellulose derivative, in a highly safe, continuous phase to obtain a W/O type emulsion and bringing the emulsion into contact with a coagulant. The method for producing porous cellulose beads is characterized by using a compound having an HLB value of 0.1 or higher but less than 1.8 as a surfactant. The problem was thus able to be solved.
(FR) La présente invention concerne un procédé de production de perles poreuses de cellulose, qui consiste à disperser une phase, qui doit être une phase dispersée et qui comprend soit de la cellulose, soit un dérivé de cellulose, dans une phase continue hautement sûre pour obtenir une émulsion de type E/H et à amener l'émulsion en contact avec un coagulant. Le procédé de production de perles poreuses de cellulose est caractérisé par l'utilisation d'un composé possédant une valeur BHL de 0,1 ou plus mais inférieure à 1,8 en tant que tensioactif. Le problème a ainsi pu être résolu.
(JA) 本発明はセルロースまたはセルロース誘導体を含有する分散相を安全性の高い連続相に分散させてW/O型エマルションとし、凝固剤と接触させて多孔質セルロースビーズを得るためのものである。HLB値が0.1以上1.8未満の化合物を界面活性剤として使用することを特徴とする、多孔質セルロースビーズの製造方法により、上記課題を解決することができた。
