Efficient method for the synthesis of fatty acid amide from soybean oil methyl ester catalysed by modified CaO
Bibliographic record
Abstract
A new method for the heterogeneous synthesis of ethanolamide from soybean oil methyl ester and monoethanolamine/diethanolamine has been established by using CaO and modified CaO as the solid basic catalyst. As the results show, the commercial CaO catalyst gives a high yield (80.2%) of monoethanolamide with high purity at a ratio of methyl ester to amine of 1: 2 after 3 h under the reaction temperature of 130°C over modified CaO. The yield was greatly enhanced to 96.3% after commercial CaO was modified by benzyl bromide in a simple way. Moreover, this catalyst shows a promising future in providing an environmentally clean process for the industrial applications. The effects of modification and reaction conditions on yields as well as the possible reaction mechanism were discussed. Further investigation indicated that the structure of ethanolamine has a great effect on the yield of monoethanolamide.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
