본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 당 및 색체에 대한 흡착제의 체류를 도식적으로 표현한 것이다. 제 2 도는 흡착제에 의해 상대 체류를 도식적으로 표현한 것이다. 제 3 도는 X형 흡착제에 의해 당의 체류를 도식적으로 표현한 것이다.1 is a graphical representation of the retention of adsorbent on sugar and color. 2 is a schematic representation of relative retention by an adsorbent. 3 is a schematic representation of the retention of sugars by an X-type adsorbent.

Claims (7)

아라비노오스 및 적어도 하나의 다른 모노세커라이드를 함유한 수성급성혼합물로부터 아라비노오스를 분리하고, 그것은 흡착조건하에 양이온 교환 자리에서 칼슘양이온을 가진 Y형 또는 X형 제올라이트로 구성된 바륨-유리흡착제와 상기 혼합물을 접촉하여 알도펜토오스 및 알도헥소오스로 구성되는 기로부터 선택되고, 다른 모노세커라이드를 실제로 제거하여 상기 아라비노오스를 선택적으로 흡착하고, 흡착제와 접촉으로부터 비흡착된 부분의 급송혼합물을 제거한후, 탈착조건에서 탈착에 의해 고순도의 아라비노오스를 회수하는 것을 특징으로 하는 방법.Separating arabinose from a water-soluble mixture containing arabinose and at least one other monosaccharide, it contains a barium-glass adsorbent composed of Y or X zeolites with calcium cations at cation exchange sites under adsorption conditions. Contacting the mixture and selecting from the group consisting of aldopentose and aldohexose, and actually removing other monosaccharides to selectively adsorb the arabinose and adsorbing the feed mixture of the nonadsorbed portion from contact with the adsorbent. After removal, recovering high purity arabinose by desorption under desorption conditions. 제 1 항에 있어서, 상기 급성혼합물이 크실로오스, 글루코오스, 갈락토오스, 만노오스 및 람노오스로 구성된 기로부터 선택되는 아라비노오스 및 적어도 하나의 다른 모노세커라이드를 함유하는 것을 특징으로 하는 방법.2. The method of claim 1, wherein said acute mixture contains arabinose and at least one other monosaccharide selected from the group consisting of xylose, glucose, galactose, mannose and rhamnose. 제 1 항에 있어서, 상기 탈착제가 물로 구성되는 것을 특징으로 하는 방법.The method of claim 1 wherein the desorbent is comprised of water. 제 3 항에 있어서, 상기 탈착제가 양이온교환 자리에서 칼슘 양이온을 가진 Y형 제올라이트로 구성되는 것을 특징으로 하는 방법.4. The method of claim 3 wherein said desorbent consists of a Y-type zeolite having a calcium cation at the cation exchange site. 제 1 항에 있어서, 상기 분리가 가상유동상 흐름공정도의 장치에 의해 영향을 받는 것을 특징으로 하는 방법.The method of claim 1 wherein said separation is effected by an apparatus of a virtual fluidized bed flow chart. 제 1 항에 있어서, 상기 가상유동상 공정도가 향류흐름을 사용하는 것을 특징으로 하는 방법.The method of claim 1, wherein the virtual fluidized bed process flow uses countercurrent flow. 제 5 항에 있어서, 상기 가상유동상 공정도가 병류흐름을 사용하는 것을 특징으로 하는 방법.6. The method of claim 5, wherein the virtual fluidized bed flow chart uses cocurrent flow. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
