It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The oxidative alkoxylation of zinc phosphide to tributyl phosphate occurred at a high rate and with high selectivity in a solution of FeCl 3 -I 2 in butanol at 50–70°C. The kinetic characteristics and optimum conditions of the process were determined. The experimental and literature data were used to identify key stages of the formation of tributyl phosphate in the presence of the mixed catalytic system.
