Abstract
본 발명은 고수율로 비스(벤질리덴)솔비톨류를 제조하는 방법을 제공하며, 이 방법은 솔비톨 수용액과 벤즈알데히드를 산 촉매의 존재하에서 유기용매중에서 반응시켜 비스(벤질리덴)솔비톨류를 제조하는 방법에 있어서, 상기 방법이 솔비톨 수용액과 솔비톨 1몰에 대해 약 2몰의 벤즈알데히드와의 혼합물을 용기용매 및 산 촉매와 혼합하는 단계; 상기 혼합물에 음이온 또는 비이온 계면활성제를 첨가하여 가열하는 단계; 및 유기용매를 물과 함께 끓는 혼합물로서 증류 제거하고 생성된(벤질리덴)솔비톨류를 분리하는 단계를 포함함을 특징으로 한다.The present invention provides a method for preparing bis (benzylidene) sorbitol in high yield, the method for producing bis (benzylidene) sorbitol by reacting aqueous solution of sorbitol and benzaldehyde in an organic solvent in the presence of an acid catalyst. The process according to claim 1, further comprising the steps of: mixing a mixture of an aqueous sorbitol solution with about 2 moles of benzaldehyde per mole of sorbitol with a vessel solvent and an acid catalyst; Heating by adding an anionic or nonionic surfactant to the mixture; And distilling off the organic solvent as a boiling mixture with water and separating the resulting (benzylidene) sorbitols.
