Synthesis of TRIP and Analysis of Phosphate Salt Impurities
Open accessAbstract
The chiral phosphoric acid TRIP, a useful Brønsted acid catalyst, easily becomes contaminated with metal impurities in the form of phosphate salts during synthesis.This significantly reduces the content of free acid in the product which can hamper the catalytic activity.Methods to easily judge whether TRIP contains mainly the free acid or phosphate salts are presented, using 1 H NMR spectroscopy or a simple pH test.An improved synthetic protocol for TRIP was established that reliably produces the free acid.

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.
