Phosphonium, tetrabutyl-, hydroxide (1:1) → HCID 86626713, compound

Participants

Reaction Steps

At 0° C., 3.54 g of N-acetylglycinate (by Tokyo Chemical) was added to 20.0 g of tetrabutylphosphonium hydroxide (aqueous 41.4% solution, by Hokko Chemical), and stirred for 10 minutes. Using an evaporator, the pressure was reduced to 40 to 50 mmHg, and this was concentrated at 60 to 80° C. for 2 hours, and then at 90° C. for 5 hours. At room temperature, this was again dissolved in 14.2 ml of ethyl acetate (Junsei Chemical). Using an evaporator, the pressure was reduced to 40 to 50 mmHg, and this was concentrated at 70 to 90° C. for 3 hours. Thus, 11.7 g of tetrabutylphosphonium N-acetylglycinate (purity: 96.9%) was obtained as an oily compound. The obtained ionic liquid had the same properties as in Production Example 16.
