ESTUDO DA REAÇÃO DE TRANSESTERIFICAÇÃO DO ÓLEO DE GIRASSOL USANDO EXTRAÇÃO COM SOLVENTE EM DUAS FASES
Bibliographic record
Abstract
Neste projeto estudou-se a extração de óleo de sementes de girassol com hexano, obtendo-se uma mistura de óleo e solvente que foi posteriormente transesterificada com metanol e KOH, em batelada. A reação foi conduzida com temperatura constante de 45 ºC, por 1 hora, tendo o hexano papel de co-solvente no meio reacional. Foi analisada nessa reação a influência da relação molar metanol / óleo e da quantidade de catalisador em relação à massa de óleo. O rendimento reacional foi analisado por cromatografia gasosa. Determinou-se que o teor de umidade da semente é de 8,45% e que o teor de óleo contido na oleaginosa é de 26,5%, sendo necessárias 3,5 horas para se atingir a máxima extração. Fez-se um planejamento fatorial 2

How this classification was reachedexpand
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.
