Claims (7)

락토오즈 및 보렉스의 알카리성 수용액을 제조하고 80℃이상의 온도에서 가열하고, 생성된 전환생성물로부터 락톨로오즈를 분리하는 방법에 있어서, 보렉스와는 별도로, 실질적으로 알카리성 물질을 용액에 전혀 가하지 않음을 특징으로 하는 방법.A process for preparing an alkaline aqueous solution of lactose and borex, heating at a temperature of at least 80 ° C., and separating lactoloose from the resulting conversion product, substantially free from addition of borex, substantially no alkaline substance to the solution. Characterized by the above. 제1항에 있어서, 보렉스가 붕산 수용액내에서, 바람직하게는 락토오즈와 함께 동시에 제조하며, 나트륨이온을 전환 생성물 용액으로 부터 전기 투석에 의해 봉산용액으로 이동시킴을 특징으로 하는 방법.Process according to claim 1, characterized in that borex is prepared simultaneously in aqueous boric acid solution, preferably together with lactose, and transfers sodium ions from the conversion product solution to the sealing acid solution by electrodialysis. 제1항에 있어서, 나트륨 이온을 약산 이온교환기 및 그후보다 강한 산 이온 교환기에 의해 실질적으로 가능한한 신속히 전환생성을 용액으로부터 제거시킴을 특징으로 하는 방법.The method of claim 1, wherein the sodium ions are removed from the solution substantially as quickly as possible by a weak acid ion exchanger and then a stronger acid ion exchanger. 제3항에 있어서, 약산 이온교환기가 붕산과 함께 적어도 부분적으로 재생되며, 상기 재생중 형성된 보렉스를 제1항의 방법에서 적어도 부분적으로 사용함을 특징으로 하는 방법.4. A method according to claim 3, wherein the weak acid ion exchanger is at least partially regenerated with boric acid and the borex formed during the regeneration is at least partially used in the method of claim 1. 제1 내지 4항중 어느 한항에 있어서, 락툴로오즈의 분리를 위해, 반응 생성물 용액을 나트륨이온의 분리후, 보레이트 이온의 분리전, 바람직하게는 15 내지 20% 무수 물질로 증발시킨 후, 바람직하게 30 내지 60℃에서, 물을 용출제로서 사용하여 약염기성 이온교환기로 충진된 긴 크로마토그래피 컬럼을 통과시킴을 특징으로 하는 방법.5. The method according to claim 1, wherein for the separation of lactulose, the reaction product solution is separated after sodium ions, before evaporation of borate ions, preferably with 15-20% anhydrous material, and preferably At 30 to 60 ° C., characterized in that water is passed through a long chromatography column packed with a weakly basic ion exchanger using eluent. 제1 내지 5항중 어느 한항에 있어서, 락툴로오즈의 분말의 제조를 위하여, 무수물질을 기준으로 하여 적어도 90%의 순도를 갖는 농축 락툴로오즈 용액을 바람직하게는 교반시키면서 락툴로오즈 분말에 매우 서서히 첨가, 바람직하게는 분무시키고, 매우 급속히, 미세하게 분배시켜, 락툴로오즈 용액이 항상 분말 입자의 표면상에서 박막을 형성하도록 하고, 분말 입자상에 고체 물질을 생성시킴을 특징으로 하는 방법.The method according to any one of claims 1 to 5, characterized in that for the preparation of the powder of lactulose, concentrated lactulose solutions having a purity of at least 90% based on anhydrous substances are preferably added to the lactulose powder, preferably with stirring. Adding slowly, preferably nebulizing, very rapidly and finely dispensing so that the lactulose solution always forms a thin film on the surface of the powder particles, producing a solid material on the powder particles. 제1항 내지 6항의 방법에 따라 제조된 락툴로오즈.Lactulose prepared according to the method of claims 1 to 6. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
