Señores, hice este experimento, y lo calenté a 125 grados, porque el ácido fosfórico se calienta a 130 grados, habrá gas hidrógeno de fosfato (tóxico). ¿Hay alguna forma de evitarlos?

se puede utilizar la absorción de PH3 con NaClO y NaOH
H3PO2 se destruye a 170 C

You want a molar equivalent , these are hypothetical amounts, but say the the 6g of ephedrine is 20mmol of one mol of ephedrine then you'd want 20mmol equivalent of pseudo.im by no mean a pro and have never even looked up the molecular weight of either of them put that's the idea .
There's a post on here somewhere I believe from patten that is very detailed and informative about the subject definitely look it up because this is something that is very important in all reactions.
Sincerely B

hola, tengo una pregunta: ¿en lugar de yodo se podría utilizar yodo potásico? Porque el yodo potásico se compra mucho más fácilmente.

Se puede utilizar yodo potásico para fabricar yodo. Se puede hacer en una perezosa tarde de domingo.

Pida respuestas a expertos porque yo he fracasado y he gastado mucho dinero y materiales.

Profesor, ¿puedo utilizar DCM en su lugar sin destilación y pasar directamente al cloruro de hidrógeno con sobrepeso?

You can do this, but it is better to extract into the water layer when acidification and evaporate part of the water. You can use aq. HCl

You must control the boiling to avoid problems with the volcano. Use boiling chips. Change the weight you need according to the specified proportions.
