Abstract

PURPOSE:To separate water from the mixture of organic solvent and water by using a compound which is precipitated through forming complex crystal with water. CONSTITUTION:A low alkyl group in the formula is 1-6C straight chain or branched alkyl group and cis-terpin is an easily obtainable compound. This compound is thrown in water-contg. organic solvent soluble in water as a solid or if necessary, it is effectively heated to dissolve or to melt. Since a complex is formed with one molecule of water per one molecule of said compound, suitable amount is added as its usage in accordance with the water content. Contact time of more than one hour is necessary. Anhydrous organic solvent can be obtained by filtration because the complex is precipitated at room temp. or by cooling.

As a method for contacting with a water-containing organic solvent, it is possible to simply drop the material into a solid water-containing organic solvent, but it is generally more efficient to dissolve or melt the material by heating as necessary.

Since one molecule of compound (I) forms a complex with one molecule of water, an appropriate range may be determined based on the water content in the water-containing organic solvent.

The temperature during contact is not particularly limited and may usually be room temperature, but may be heated to maintain the solid in a dissolved or molten state.

通常1時間以上行なうのが適当である。
The contact time is also not particularly limited, but it is usually appropriate to carry out the contact for one hour or more in order to complete the complex formation.

Since the complex usually precipitates as a solid at room temperature or upon cooling, it can be separated to obtain a concentrated water-containing organic solvent or anhydrous organic solvent as a P solution. If necessary, a pure product can be obtained by purification such as distillation. On the other hand, complexes with water can be reused because water is easily released by heating, usually above the boiling point of water.
