行するものと思われる。[Detailed Description of the Invention] Furfural obtained from corn and other raw materials, and furfuryl alcohol obtained from it, are excellent and effective solvents for organic substances, but the drawback is that they do not release water for several days after distillation. It also turns black. Therefore, the field of its use is severely limited. The inventors of the present invention have kept this point in mind and have conducted repeated research. As a result, in the presence of an appropriate amount of alkali in furfuryl alcohol, ethylene oxide is added to 1 mole of furfuryl alcohol on an average of 1 to 1.
The compound obtained by adding 2 moles was found to be pale yellow and transparent. Moreover, its color does not change for several years, even under direct sunlight. Of course, its effectiveness as a solvent is not inferior to that of furfural or furfuryl alcohol per mole. The reaction in this case is thought to proceed as follows.

ある。回収時の条件の一例を平均１５モルのエチレンオ
キソード付加物で示すと次のようである。Although it varies depending on the purpose of use, it seems appropriate for n to be 1 to 2. This is because as n increases, the boiling point during distillation increases. It is more advantageous to use vacuum distillation for solvent recovery. An example of the conditions during recovery based on an average of 15 moles of ethylene oxide adduct is as follows.
沸点８０〜１２５℃ 減圧５龍Ｈ１
エテレンオキンード付加の反応温度は１８０〜１８５°
Ｃである。付加モル数は増量によって定める。Boiling point: 80-125°C Reduced pressure 5 Dragon H1 Ethelene Oquine addition reaction temperature is 180-185°
It is C. The number of moles added is determined by increasing the amount.

The temperature shall be 185°C. Since this is an exothermic reaction, be careful not to raise the temperature. The reaction was stopped when the reaction content increased by 185 parts. Next, it is distilled under reduced pressure. The freezing point of the pale yellow liquid is below -15°C, the yield is 98%, and the product does not change color even when left in a bright place.
