摘要:
The present invention relates to a method for producing and purifying an anhydrous sugar alcohol in high yield and to a high degree of purity by means of a simple process and device, the invention comprising: a step in which a sugar alcohol and an acid catalyst are reacted in a reactor while at the same time evaporating the product therefrom; a step in which the evaporated product is cooled so as to remove water and obtain a crude anhydrous sugar alcohol; and a step in which the crude anhydrous sugar alcohol is introduced into a melt-crystallization process, thereby obtaining a high purity anhydrous sugar alcohol.

The present invention relates to a method for continuously producing an anhydrous sugar alcohol in high yield and to a high degree of purity by means of a simple process and device in which a sugar alcohol and an acid catalyst are reacted in a reactor while at the same time evaporating the product therefrom, and the product that has been evaporated to the upper part of the reactor is cooled so as to remove water and obtain a crude anhydrous sugar alcohol while at the same recycling, to the reactor, the residue obtained in the lower part of the reactor.
摘要:
The present invention relates to bicyclic tetrahydrofuran lactone derivatives and a preparation method thereof. Particularly, the present invention relates to a process of preparing the above compounds by performing an intramolecular cyclization of tetrahydrofuran-allenic acid derivatives in the presence of a phenyl halide, a palladium catalyst and a base.
