Cellulose dissolution with polar ionic liquids under mild conditions: required factors for anions

Fukaya, Yukinobu, Hayashi, Kensaku, Wada, Masahisa, Ohno, Hiroyuki·2008·Green Chem.

Abstract

A series of alkylimidazolium salts containing dimethyl phosphate, methyl methylphosphonate, or methyl phosphonate prepared by a facile, one-pot procedure were obtained as room temperature ionic liquids, which have the potential to solubilize cellulose under mild conditions. Especially, N-ethyl-N′-methylimidazolium methylphosphonate enables the preparation of 10 wt% cellulose solution by keeping it at 45 °C for 30 min with stirring and rendered soluble 2–4 wt% cellulose without pretreatments and heating.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
